Pump Size Table

The Pump Size Table houses the individual pump information for the product lines. The table is designed to capture data specific for each pump size thus allowing each pump's behavior to be controlled. The table also provides functionality to control what pumps are available in the Selector, this allows the database to be populated regardless if pumps are in production or still in development. See below to learn how to populate the table and about the information it houses.

How do I populate the Pump Size Table?

• To populate the Pump Size Table:

1. In the navigational tree, open the Product line data folder.

2. Click on the product line to populate.

This image shows the B8 (Standard) product line is selected.

3. The data manager pane will display the Pump Size Table.

   

   This example shows the Pump Size Table displayed for the B8 (Standard) product line.

4. Enter a pump size and type then populate the remaining fields in the table. To learn more about each field, click on the column names below.

• Pump size and type Enter a unique pump size and type for each pump in the product line. This information will be visible in the Selector to identify the different pumps.

• Order Enter a numerical value representing the order placement for which the pump size are to be displayed. Pumps are displayed in ascending order. (1,2,3,4, etc.).

• Supplier ID Enter a specific ID for each pump size. ID's must be unique for every pump size in an organization. Pump ID's will be displayed in the Selector's pump size list table.

• Speed, minimum limit [rpm] Enter the minimum speed range for the pump. Remember a pump can be represented by more than one curve, the speed range must take this into account when applicable. Below show a typical example of a pump using three separate curves.
  
  Curve1: 1800 to 3600RPM (2 pole).
  Curve2: 1200 to 1800RPM (4 pole).
  Curve3: 900 to 1200RPM (6 pole).
  
  Pump's, speed range: 901 to 3600RPM.
  
  Rule: The rated speed > curve minimum limit and the rated speed <= curve max limit.

• Speed, maximum limit [rpm] Enter the maximum speed range for the pump. Remember a pump can be represented by more than one curve, the speed range must take this into account when applicable. Below show a typical example of a pump using three separate curves.
  
  Curve1: 1800 to 3600RPM (2 pole).
  Curve2: 1200 to 1800RPM (4 pole).
  Curve3: 900 to 1200RPM (6 pole).
  
  Pump's, speed range: 901 to 3600RPM.
  
  Rule: The rated speed > curve minimum limit and the rated speed <= curve max limit.

• Speed increment [rpm] Enter the increment be used to round any speed which is calculated
  as a result of the user's Hz or the Selector performing a speed reduction calculation.

• Stages, minimum Enter the minimum number of stages supported by the pump. The minimum
  must be greater than zero.

• Stages, maximum Enter the maximum number of stages supported by the pump.

• Allowable stages If applicable, enter the allowable stages that a pump can be selected between the minimum and maximum stage limits. The Selector will evaluate to the stages specified en lieu of any stage between the minimum and maximum values.
  
  Example: A multistage pump has a stage range from 1-10, however it's only manufactured in 1,2,4,6,8,& 10 stages. Therefore to limit the stages the allowable stage field is populated as follows: 1:2:4:6:8:10

• Shaft power limit [kW/1000rpm] Enter a value that represents the strongest shaft material that can be supplied with the pump.

• Solids diameter limit [mm] Enter the maximum solids diameter that can be handled by the pump.

• Cutwater diameter [mm] The cutwater diameter ratio (shown in search results and the performance datasheet) = Rated diameter / cutwater diameter.

• Variable speed, minimum limit [rpm] This field is only applicable when using the "Multi-Speed Curve" page in the Selector. If applicable, populate the minimum speed limit that is acceptable for the pump size when using the multi-speed page. If set to zero, the curve minimum speed will be used. This limit can also be set at the curve level. If both are in use (not zero), the curve boundary level will take precedence.

Important: When defining the margins below, keep in mind that when using the"Search Using Conditions of Service" option in the Selector, pumps which fall within the margins are designated  as a "near miss” and are displayed on the search results page. Pumps falling outside the margins are considered full rejects and will not be displayed.

• Reject margin, minimum speed [%] Enter a percent value for the allowable margin for minimum speed that a "near miss" will result. Any selection within the margin will be considered a  "near miss", any selection below the margin will be considered a full reject and discarded. For example: a pump's minimum speed is 500 rpm with a designated reject margin for minimum speed of 10%, as a result for any speed >= 450 rpm and <500 rpm the Selector will return a "near miss" and for any speed < 450 rpm a full reject will occur.
  Note: Regardless of the margin defined, if the curve's minimum speed is exceeded a full reject will occur.
   

• Reject margin, maximum speed [%] Enter a percent value for the allowable margin for maximum speed that a "near miss" will result. Any selection within the margin will be considered a  "near miss", any selection above the margin will be considered a full reject and discarded. For example: a pump's maximum speed is 1800 rpm with a designated reject margin for minimum speed of 10%, as a result for any speed >1800 rpm and < = 1980 rpm the Selector will return a "near miss" and for any speed > 1980 rpm a full reject will occur.
  Note: Regardless of the margin, if the curve's maximum speed is exceeded the pump will be considered a full reject and discarded.
   

• Reject margin, maximum flow [%] Enter a percent value for the allowable margin for maximum flow that a "near miss" will result. The maximum flow value is determined by the end of curve point. Any selection within the margin will be considered a  "near miss", any selection outside the margin will be considered a full reject and discarded.

• Reject margin, minimum head [%] Enter a percent value for the allowable margin for minimum head that a "near miss" will result. Any selection within the margin will be considered a  "near miss", any selection outside the margin will be considered a full reject and discarded. Click the below links to see examples on how margins are applied.
  
  - Pump using fixed trim curve with no "head margin for fixed diameter" values.
  - Pump using fixed trim curve with "head margin for fixed diameter" values.
  - Pump using fixed trim curve with "head margin and corrections.
  -Pump using curve with diameters that can be trimmed.

• Reject margin, maximum head [%] Enter a percent value for the allowable margin for maximum head that a "near miss" will result. Any selection within the margin will be considered a  "near miss", any selection outside the margin will be considered a full reject and discarded. Click the below links to see examples on how margins are applied.
  
  - Pump using fixed trim curve with no "head margin for fixed diameter" values.
  - Pump using fixed trim curve with "head margin for fixed diameter" values.
  - Pump using fixed trim curve with "head margin and corrections.
  -Pump using curve with diameters that can be trimmed.

• Reject margin, MCSF [%] Enter a percent value for the allowable margin for minimum continuos staple flow (MCSF) that a "Near Miss" will result. Any selections outside the margin will be discarded. MCSF values are defined at the curve level in the General Curve Table.

• Reject margin, shaft power [%] Enter a percent value for the allowable margin for shaft power that a "Near Miss" will result. Any selections outside the margin will be discarded. Shaft power limits are defined in the Shaft power limit [kW/1000rpm] field.

• Reject margin, NPSH [%] Enter a percent value for the allowable margin for NSPH that a "near miss" will result. Any selection within the margin will be considered a  "near miss", any selection below the margin will be considered a full reject and discarded. NPSH values are determined at the curve level in NPSH point data tables.

• Viscous CE limit for near miss If necessary, enter a value for the allowable limit for the viscous coefficient for efficiency that a "Near Miss" will result. Any selections outside the margin will be considered a full reject.

• Viscous CE limit for full reject If necessary, enter a value for the allowable limit for the viscous coefficient for efficiency that a "Full reject" will result. Any selections outside the margin will be discarded.

• Compatibility rule

• Status This selection box contains selections to activate, disable, or conceal a pump in the Selector.
  
  Select ”Active” to enable a pump. An "active" pump will be available in the Selector after the next successful deployment sequence.
  
  Select ”Redundant” to disable a pump. A "redundant" pump will not be available in the Selector after a deployment sequence or be removed from the Selector if its status was "active" in a prior deployment. This feature allows the database to be populated with pumps in production or under development eliminating the need for two separate databases.
  
  Select "Conceal" to hide a pump in the search results and size list pages in the Selector. It will be displayed in the Selector's performance datasheet mixed stage performance section when using mixed stage compatibility table.

5. Enter additional pump sizes by inserting rows using the append function.

6. Populate the fields as describe above.

Hint: To avoid "keying in" repetitive data for each pump size, insert multiple rows then use copy and paste to populated the data. (i.e. suction size, reject margins). Large amounts of data can also be copied from excel and pasted into the table.
