The verification of test for pumps include pressure test across the pump, pressure test in the air or water distribution system, and flow readings at the air or water terminal. Pump performance is plotted on its respective performance curve and an analysis of system operation is made. Pump performance testing is used for individual pumps, pump stations, or entire pumping systems. Performance testing can identify the hydraulic issues that are causing repeat failures.
A pump protector is an air release valve mounted in parallel with a liquid level sensing device. It protects submersible pumps from large debris while keeping pump intake clear.
