Properly sizing systems, utilizing well-trained operators and performing routine maintenance can help overcome day-to-day challenges.

7. Use suction stabilizers and discharge pulsation dampeners.

The pulsation dampeners remove pulsating flows from reciprocating-type positive displacement pumps, ensuring a smooth and continuous fluid flow. The result is reduced pipe vibration and longer gasket and seal life. In the case of diaphragm pumps, suction stabilizers act as accumulators and reduce pressure fluctuations that can increase diaphragm and valve wear. Use suction stabilizers to increase the NPSH value, which will decrease the energy required to draw fluid into the pump.

8. Isolate mechanical vibration

Construct a proper foundation to which the pump can be securely anchored. Install quality vibration-dampening mounts and anchoring hardware.

9. Conduct routine maintenance.

Timely replacement of wear parts results in greater pump efficiency. Pumps work best when valves seat properly or when component clearance is within the manufacturer's specification. In the case of corrosive media, periodically flush pumps with clean water or other acceptable media per the manufacturer's guidelines.

10. Train the operators.

A well-trained operator is vital for efficient operation. Train these key staff members to ensure that system performance is monitored and that routine maintenance is performed to keep the system operating at its most efficient levels. Discourage "knob turning" or ill-advised process control adjustment as a means of keeping a poor-performing system in operation. Instead, train operators to report issues with system pressure or flow rate, and organize the necessary maintenance or remedial action.
