Q: Can the pump efficiency be gauged without a pump test? A: Pump test is the best way to gauge pump performance. Pump output is usually a function of it’s efficiency. By diligent record keeping of flow and pressure developed by pumps, pump performance can be gauged on a real time basis. This is not a substitute for a pump test, however, it is usually an indication of pump performance at a very high level. It is always a good idea to keep track of flow rate and pressure developed by pumps using properly calibrated meters. SCADA systems can automatically track this and many other variables encountered in a pumping system.
