1. Pump Curve Accuracy
   Introduction What are the attributes that make one pump selection software package superior to another? Aside from all the bells and whistles, the key to a superior pump selection program is the ability to accurately reproduce the manufacturers’ performance curves and to place the pumps th ...
2. Changes to the Automatic System Resistance Curve Generation Feature on PUMP-FLO Desktop 10.6
   You asked for it! Changes to the Automatic System Resistance Curve Generation Feature on PUMP-FLO Desktop With the release of PUMP-FLO 10 we introduced a new feature: the ability to quickly and easily generate a System Resistance Curve (SRC) that runs through your design point (without having to ...
3. How to Share Selection Lists in PUMP-FLO Premium
   You can share a PUMP-FLO Premium selection list with anyone who has an email account. Share recipients don’t need a Premium subscription to view the list, but will need to create a user account if they don’t have one. Share recipients who have Premium subscriptions will be able to ma ...
4. Pump Sizing
   Selecting the proper pump is the most important step in the development of a piping system. The pump must be sized to handle the desired flow rate at the required pressure from the supply to the destination. In order to size a pump, you must take into account the change in elevation and pressur ...
5. Manual Selection in PUMP-FLO Premium
   If you’d like to add additional pumps that weren’t returned by a search, or add additional pumps to a previously saved list, you can accomplish it easily using the new Manual Selection tool in PUMP-FLO Premium. While viewing a list, click the Manual Selection link in the blue bar at ...
6. Customizing Pump Catalogs
   This article is intended for Manufacturers who want to add custom elements to their Pump Curve Catalog. The attached document describes items that can be distributed with your pump curve catalog to customize the operation of PUMP-FLO and all OEM versions of the Pump Selection software. Engineere ...
7. Specifying a Preferred Operating Region in PUMP-FLO
   It’s easy to specify a preferred operating region on a curve using PUMP-FLO. The steps are primarily the same on both our web-based selection tool at www.pump-flo.com and when using the desktop PUMP-FLO software. Figure 1. From the Design Point Search screen, go to the Advanced Cri ...
8. Formats for Centrifugal Pump Curves
   When displaying pump curves in PIPE-FLO or PUMP-FLO, the amount of information displayed on the curve varies based on the way the pump performance data was entered. In this article we will discuss both of the ways in which pump performance data can be entered in PIPE-FLO using the PUMP-FLO selec ...
9. Reading a Pump Curve
   Pump Name and Speed The customary naming of a pump provides the discharge diameter, suction diameter, and maximum impeller diameter. In figure 1 we see the pump curve for a 4x6-13 pump. That means the pump discharge nozzle diameter is 4 inches, the pump suction nozzle diameter is 6 inches, and ...
10. Pump Curve Landmarks
    Pump manufacturers provide pump head curves showing the head, and efficiency as a function of the flow rate through the pump. This knowledge base article describes the various landmarks found on a pump curve, and describes why it is so important to operate any centrifugal pump within the manufa ...
11. NPSH & Pump Selection
    Pump Net Positive Suction Head (NPSH) is one of the most misunderstood aspects of pump hydraulics and can be one of the most damaging. Many technical articles and papers have been written on the subject, but little has been written on how this damage is done. The best material on the subject is ...
12. Change in Viscosity Correction Formulas
    For viscosity corrections, previous versions of PUMP-FLO used a set of equations that were derived from Figures 71 and 72 of the Hydraulic Institute Standards (14th edition, Hydraulic Institute, 1983). Two sets of equations were used: the equations based on Figure 71 were for pumps with a best ...
13. PUMP-FLO Atmospheric Pressure Calculator
    The atmospheric pressure calculator feature in PUMP-FLO can be used to calculate the atmospheric pressure at any elevation ranging from -10,000 ft to 15,000 ft. Since the atmospheric pressure is used in the calculation of NPSHa, it is important to use the correct value for a particular elevatio ...
14. How to Generate a System Resistance Curve on PUMP-FLO.com
    There are three ways to specify a System Resistance Curve (SRC) on www.PUMP-FLO.com. A. The first method is to use the automatic system curve generator that draws a 2nd order curve from zero flow / zero head through your design point. To use this feature, simply check the 'Generate SRC' box bef ...
