5 Key Tips for Specifying a Pump

Industrial pumps and pumping systems have evolved to the level of customization and user-tailoring that pump system designers should no longer settle for standard off-the-shelf products. With this in mind, pump maker KNF Neuberger offers a blueprint of five tips for system architects who are looking for the perfect pumps for their applications.

Written by KNF and housed at the online site of PumpScout, the Tacoma, Wash.-based engineering and industrial equipment web service, 5 Key Tips for Specifying a Pump runs down the basics of diaphragm, peristaltic, and linear pumps. A successful pump design, KNF writes, minimizes cavitation effects, accounts for self-priming capability, takes into account chemical compatibility between the pump and the fluid plus particulates, and has preventative solutions for reverse flow and system leakage.

“Asking the right questions and rooting out the answers will ensure that you get the right pump on your first try,” assures the German-based multinational pump maker (U.S. headquarters in Trenton, N.J.).

What are those five key questions?

1. Have the voltage and performance requirements been defined?

2. What are the system’s electrical considerations?

3. Are vacuum and flow rates within acceptable ranges?

4. Will the temperature fluctuate?

5. How will the duty cycle play out?

KNF’s tip-sheet alludes to variable speed technology in the “new energy-conscious environment” as one critical design parameter for contemporary pump system designers. More details on each of the five considerations can be found here.
