Solutions to Common Centrifugal Pump Problems | Pumps & SystemsWhen a newly-repaired pump performs poorly, good troubleshooting procedures can help eliminate a number of possibilities—including problems with the fluid being pumped the pumpage or with the pipes, fittings or vessels that are connected to the pump the system. A savvy technician with a basic understanding of pump curves and performance parameters can quickly narrow the possibilities—especially those associated with the pump. This discussion is limited to the most common pumps in industrial and commercial applications—centrifugal pumps. The performance curves in Figure 1 illustrate how the head, flow rate, efficiency and power relate to one another for a typical centrifugal pump. As head increases, flow decreases and vice versa.

Centrifugal Pump Repair & Troubleshooting
The pump centerline of a centrifugal pump is located 2. The sea water varies two meters from high tide to low tide level. If friction loss at the suction is 0. A centrifugal pump requires 40 ft head to deliver water from low level to higher level. If pump speed is rpm, determine the impeller diameter of the centrifugal pump.
Caution: If there is little or no head or flow on startup, immediately shut off the pump and verify that sufficient fluid is in it-that the pump is primed. Much more than documents.

Many pump problems and some system problems will cause the pump to operate at a point below its normal pump curve line. Again, prlblems the pump is operating on the pump curve. The pump shaft is connected to the gas separator or the protector by a mechanical coupling at the bottom of the pump. Each stage includes an impeller and diffuser.
