Selector Help
This Selector has been designed using the criteria described below.
The need to provide a solution that can completely replace conventional methods. A complete pump selector that encompasses hydraulics, material selection, engineering data such as shaft power limits, working pressure limits, performance corrections and price index calculations for optimum selection, rather than simply a hydraulic selector that only provides hydraulic performance similar to that of pricebook performance curves.
An intuitive balance between user friendliness for the less experienced user (buyer) and functionality for the experienced user (supplier).
The need to cater for an international user base in terms of language translations, units of measure, currencies and standards (power supply, motor ratings, paper size etc.)
To navigate around this Help page, use the BackSpace key on your keyboard to perform "Back" operations.
Start Page
Click on either Search Using Conditions of Service or Select from List of Pumps.
Selecting "Search Using Conditions of Service" will take you to the Conditions of Service page.
Selecting "Select from List of Pumps" will take you to the Product Lines page.
Enter a flow and head as a minimum. Other conditions of service are described in the Advanced Instructions.
Click on the Next>> button (or press <Enter>) to display the Product Lines page. Note: If a product line has already been selected (possibly as a result of you entering the Selector from a pump suppliers website), then the Product Lines page will be skipped, and the Search Results page will be displayed.
Check the box in the first column for the product line(s) you are interested in.
Click on the Next>> button (or press <Enter>). The next page that will be displayed depends on the selection you made at the Start page.
If you selected "Search Using Conditions of Service", the next page will be the Search Results page.
If you selected "Select from List of Pumps", the next page will be the Pump Size List page.
Adjust the Hz drop-down as necessary and click on the Recalculate button.
Adjust the speed, stages and impeller diameter (if permitted) as necessary.
Click on the required pump size. This will present the Performance Datasheet page.
Review the list of possible selections. Note the following:
The Result column indicates whether the selection is an Acceptable selection or a Near miss.
Check multiple checkboxes in the Display Thumbnails column and click on the Thumbnail Curves tab to display the Thumbnail Curves page. From the Thumbnail Curves page you can either:
Click on the preferred curve to display the Performance Datasheet.
Click on the Search Results tab to return to the Search Results page.
From the Search Results page, click on the preferred pump size link to display the Performance Datasheet.
Near miss selections are those that do not fully conform to the conditions of service, but warrant being displayed to the user for consideration. You can click on a near miss selection to display the Performance Datasheet and then experiment with the conditions of service to turn the selection into an acceptable selection.
Review the performance data and the performance curve at the bottom of the page.
Make any necessary adjustments to the conditions of service directly on the datasheet and click the Recalculate button to display updated performance.
Click the Print button to display the datasheet in PDF format.
The Start page is where you can decide how to use the Selector. There are currently two different ways of using the Selector, as described below.
Search Using Conditions of Service
This method is the conventional approach, that allows the user to define conditions of service (flow, head, temperature, pressure etc.) and then have the Selector search for suitable products and pumps that meet those conditions of service.
Select from List of Pumps
This method is useful under the following situations:
When you already know the product and the pump size. For example, in a replacement pump situation.
When you want to investigate why a particular pump size was not included in Search Results.
The Conditions of Service Page contains the following twisties. Clcik on a twistie to toggle between expanded and collapsed modes. Note: The pump supplier can dictate the default mode of twisties and even dictate that they are hidden.
Header Information Twistie
Item number
This is the customer's item number, used to identify each item within a multi-item inquiry or proposal. The data entered here will appear on all output documents such as the Performance Datasheet and the Performance Curve. Example: "P101 A/B"
Service
This is an additional field usually provided by the customer and is used to further identify the item. Example: "Booster Pump".
Quantity of pumps
This is the number of pumps required by the customer for this item. This data will be transferred to the Configurator and will be used as the default quantity for options and to calculate total item and proposal prices.
This field is designed to help a user who is not familiar with your product portfolio. The selected industry will be used to filter the available products in the Product Lines page to only those that are applicable to that industry. This drop-down also appears on the Product Lines page to allow the user to easily determine which products relate to specific industries. The options in this drop-down are defined and controlled by the pump supplier, and can be used to control other performance option lists such as Liquid type. Examples: "Building services", "Chemical process".
This field is designed to help a user who is not familiar with your product portfolio. The selected product classification will be used to filter the available products in the Product Lines page to only those that are applicable to that classification. This drop-down also appears on the Product Lines page to allow the user to easily determine which products relate to specific classifications. The options in this drop-down are defined and controlled by the pump supplier. Example: "Overhung, flexibly coupled".
This field is designed to help a user who is not familiar with your product portfolio. The selected orientation will be used to filter the available products in the Product Lines page to only those that are applicable to that orientation. This drop-down also appears on the Product Lines page to allow the user to easily determine the orientation of each product. The options in this drop-down are defined and controlled by the pump supplier. Example: "Horizontal".
Basic Operating Conditions Twistie
This is the customer's required flowrate and is a required field (highlighted in bold). In addition to sizing the pump, this value is also used to filter the products on the Product Lines page such that if the overall flow limit of a product line is exceeded, the product line will be displayed "greyed out". Changing the unit drop-down will not change any entered value. Changing units by using the Units button will convert any entered value.
This is the customer's required head (TDH) and is a required field (highlighted in bold). In addition to sizing the pump, this value is also used to filter the products on the Product Lines page such that if the overall head limit of a product line is exceeded, the product line will not be displayed. Changing the unit drop-down will not change any entered value. Changing units by using the Units button will convert any entered value.
Frequency
Select the Hz for the country of destination.
Search Criteria
This dicates how product lines are searched and the resultant list of suitable pumps displayed in Search Results. The possible options are described below.
All suitable speeds. Each pump size will be evaluated at all possible synchronous speeds between the minimum and maximum allowable speed. For slow speed pumps this may result in more than one selection for the same pump size.
Set synchronous speed. This option allows you to specify a particular synchronous speed. Each pump will be evaluated at only this synchronous speed.
Set synchronous speed limits. This option allows you to specify synchronous speed limits. Each pump will be evaluated only at synchronous speeds between these limits.
Set actual speed. This option allows you to specify a particular speed, for example a diesel engine speed of 2000 rpm . Each pump will be evaluated at only this speed.
Variable speed, maximum diameter. Each pump will be evaluated at maximum impeller diameter. Each pump will be selected at a speed that coincides with the required flow and head.
Note: The pump supplier can specify that a product line is a "variable speed" product line, and in this case the Variable speed, maximum diameter mode will be used for the All suitable speeds option.
Advanced Operating Conditions Twistie
The default value for these fields is zero. The value entered in this field will be checked with the limits described below.
If the overall suction pressure limit of a product line is exceeded, the product line will be "greyed out" on the Product Lines page.
If the maximum allowed suction pressure limit for a pump size is exceeded, the selection will be displayed as a Near miss on the Search Results page and on the Performance Datasheet page.
If the combination of this value and the pressure at shutoff for the rated impeller diameter exceeds the maximum allowed working pressure, the selection will be displayed as a Near miss on the Search Results page and on the Performance Datasheet page.
NPSHa, rated
The default value for this field is Ample. If a value is entered, it will be checked with the NPSH required by each selection, and if inadequate, the selection will be displayed as a Near miss on the Search Results page and the Performance Datasheet page. If a value has been entered for the NPSH margin in the Selection Constraints section, this value will be added to the NPSH required before comparing it with the NPSH available.
This field allows the user to define a liquid type, that can then be used to control other performance options and configuration options, such as the pump material of construction and the mechanical seal. The options in this drop-down are defined and controlled by the pump supplier. Example: "Sea water".
Additional liquid description
This field allows the user to provide an enhanced description of the liquid, that will appear on all output pages such as the Performance Datasheet and the Performance Curve.
This field is used to check the maximum solids diameter of the product line and individual pump sizes. If the overall product line solids diameter limit is exceeded, it will not be displayed on the Product Lines page. If an individual pump size solids diameter limit is exceeded, it will be displayed as a Near miss, with the reason why, on the Search Results page and on the Performance Datasheet page.
The default value for this field is 20 deg.C. The value entered in this field will be checked with the limits described below.
If the overall temperature limit of a product line is exceeded, the product line will not be displayed on the Product Lines page.
If the maximum temperature limit for a pump size is exceeded, the selection will be displayed as a Near miss on the Search Results page and on the Performance Datasheet page.
The temperature is used to determine the flange pressure limits of a pump, and if the maximum working pressure exceeds this limit, the selection will be displayed as a Near miss on the Search Results page and on the Performance Datasheet page.
Fluid density, rated
This field allows the user to specify the rated fluid density of the liquid. The value is used to convert between TDH and pressure and is used in calculating power (kW) performance data.
This field allows the user to specify the rated viscosity of the liquid. The value is used to correct water pump performance data to viscous pump performance data. The current selection algorithms use the Hydraulic Institute viscosity correction methods. Other supplier defined methods can be incorporated.
This field allows the user to specify how the driver is sized.
Rated power will select a driver rating that is greater than or equal to the power required by the pump at rated flow for the rated impeller diameter, plus any margin specified in the Margin over specification field.
Maximum power will select a driver rating that is greater than or equal to the maximum power required by the pump for the rated impeller diameter, plus any margin specified in the Margin over specification field.
API 610 8th Edition will select a driver rating that is greater than or equal to the criteria specified by API 610 8th Edition, plus any margin specified in the Margin over specification field.
ISO 5199 will select a driver rating that is greater than or equal to the criteria specified by ISO 5199, plus any margin specified in the Margin over specification field.
The driver ratings are selected from a pre-defined list of motor ratings as described in the Motor rating field of the Performance Datasheet page.
This field provides the user the ability to add a margin over the selected Driver sizing specification. This allows for the driver to be sized to specific customer requirements. Example: Rated power + 10%.
This field allows the user to specify whether the driver should have a service factor. A 15.0 kW motor with a service factor of 1.25 is safe to operate up to 18.75 kW.
Use service factor?
This field allows the user to request that any specified Service factor is utilized when sizing the driver. For a pump with a rated power of 18.5 kW, a 15.0 kW motor with a service factor of 1.25 would be adequate for a Driver sizing specification of Rated power if the user specified that the service factor could be used when sizing the driver.
This field allows the user to choose between an IEC motor or a NEMA motor. The choice will affect the list of standard ratings used to determine the Motor rating.
Selection Constraints Twistie
Hydraulic selection specification
This field allows the user to have all selections made in accordance with industry standard selection specifications, such as API 610 or NFPA. Again the options in this list are definable by the supplier and rules can be defined that dictate what specifications are shown basis the selection of other drop-down lists. Selection of a specification will apply all the selection criteria for that specification during the pump selection process, such as minimum head rise to shutoff and preferred operating regions around the best efficiency point. Any pump not in accordance with the specification will be displayed as a Near miss along with the reason(s) for non-conformance.
Minimum head rise to shutoff
This field allows the user to specify any requirement they have in terms of a head rise to shutoff. Any selections not in conformance with the specified value will be displayed as a Near miss along with the reason for non-conformance.
Stable head/flow curve required?
This field allows the user to specify whether selections shall have a stable (continuously falling, non-drooping) head curve. Any selections not in conformance will be displayed as a Near miss along with the reason for non-conformance.
NPSH margin
This field allows the user to specify a margin to be included when evaluating the NPSH required. The equation [NPSHr + NPSHmargin >= NPSHa] must be satisfied before a selection is accepted. Selections with inadequate NPSHr will be displayed as a Near miss along with the reason for non-conformance.
This field is designed to help the user who may not be familiar with your portfolio of products or their compliance with particular pump construction specifications. Examples are API, ANSI, DIN and ISO. The list of specifications is defined by the supplier and the user's selection will only display product lines that are designed to meet that specification on the Product Lines page.
This field is designed to help the user who may not be familiar with your portfolio of products or their available materials. The list contains generic material descriptions such as "Cast iron", "Carbon steel", "Stainless steel" etc. Assuming the user knows what material is suitable for pumping their liquid, they can select a generic material from this list. The selection will eliminate products from the Product Lines page that cannot be supplied in any equivalent material. For products that do have an equivalent material, that material will be selected as the default on the Product Lines page, thereby eliminating the need for the user to understand your products in detail.
System Curves Twistie
This section allows you to define up to 4 different system curves. System curves will only be displayed on the Performance Curve if the Display checkbox is checked.
This page displays the list of product lines suitable for the conditions of service specified. To view only suitable product lines, change the "All" drop-down in the "Product Line" column to "Acceptable" and click the "Recalculate" button or press <Enter>. If possible, the cause for unacceptance will be highlighted in bold red in the other data columns.
The following drop-downs are available for the user to filter the list of product lines to match the specified criteria:
The Material of Construction column displays the available and suitable materials for each product line. The pump supplier can define rules to insure only materials that are compatible with the conditions of service are displayed. For example, if the user selected a Liquid Type of "Hydrocarbon" on the Conditions of Service page, the pump supplier may choose to eliminate "Cast iron" from the list.
The pump supplier also has the capability to set the material to be auto-selected by the Selector. If this is enabled, "Auto" will appear in the list of materials and be the default. Assuming the user leaves "Auto" as the selected option the Selector will upgrade material as defined by the supplier to select a material compatible with the suction and working pressure requirements. For example, the Selector will calculate the maximum working pressure for the conditions of service at the rated diameter, zero flow and compare this to the working pressure limit of the first material, say cast iron. If cast iron was deemed to be inadequate the Selector will upgrade as defined by the supplier to say carbon steel in an attempt to find a material that meets the pressure requirements.
In addition to fully acceptable selections, the Selector presents "Near Miss" selections allowing the user to evaluate potential more optimum selections should the user be prepared to relax the conditions of service slightly or the pump supplier be prepared to stretch their published performance. The criteria for setting Near Miss margins is specified by the pump supplier.
The following functionality can be performed at this page:
Display thumbnail curves by checking multiple pumps and clicking the Thumbnail Curves tab.
By default the Search Results are sorted in descending efficiency order. You can sort on any column by clicking the sort buttons immediately beneath the column headings.
To view the Performance Datasheet for a specific pump, click the pump link in the Pump Size column.
Hide "Near Miss" selections by clicking on the Hide Near Misses checkbox.
Certain specific conditions of service can be directly edited on the Performance Datasheet page. Upon making any edit the "Recalculate" link will become visible, and you can either click this link or press <Enter> to regenerate the current selection to represent the changed conditions.
To evaluate different speeds (or stages for multistage pumps), insure the relevant "Set @" checkbox is checked, specify your required data and recalculate.
Printable versions of the Performance Datasheet as well as a portrait and landscape curve are available by clicking on the Print button.
This field displays the selected motor rating in both kW and hp units. The basis for selecting the motor rating and the reason for displaying the value in both Metric and US units is described below.
There are two primary standards for motor ratings; IEC and NEMA. IEC is based on kW ratings and NEMA is based on hp ratings. The user can specify which type of motor (IEC or NEMA) is required in the Driver design field of the Conditions of Service page.
If an IEC motor type is specified, the motor rating is selected from a list of standard IEC kW ratings. If a NEMA motor type is specified, the motor rating is selected from a list of standard NEMA hp ratings.
If the user requires a NEMA motor, but has selected Metric units, only displaying a kW rating for a NEMA motor would result in an unintelligible value (7.457 kW for a 10.0 hp rating). Therefore, the displayed value in this instance would be "7.46 kW / 10.00 hp". Different permutations of motor type and units result in one of the following displayed values; "7.46 kW / 10.00 hp", "7.50 kW / 10.06 hp", "10.00 hp / 7.46 kW", "10.06 hp / 7.50 kW"
Certain specific conditions of service can be directly edited on the Performance Datasheet page. Upon making any edit the "Recalculate" link will become visible, and you can either click this link or press <Enter> to regenerate the current selection to represent the changed conditions.
The global menu options appear at the very top of each page. Depending on your particular priviliges, some of these may not be visible.
Quote Manager
This will take you to the Quote Manager which allows you to manage your database of customers, quotes and items. If you have the appropriate priviliges, then you can view all customer, quotes and items for your entire organization.
