Submersible Pump Comprehensive Performance Testing System Submersible Pump test

Overview

The submersible pump test bench is a hardware and software system primarily used for factory and type testing of submersible pumps. The testing system consists of a flow rate and speed tester, a pressure and head tester, a single/three-phase electrical parameter measuring instrument, a live winding temperature rise tester, and flow sensors, pressure transmitters, pressure gauges, etc.

Test Items

Flow rate, pressure (head), speed, voltage, current, power, efficiency, temperature rise, etc.

Test Functions

No-load test, load/performance test, cavitation test, temperature rise test, locked rotor test, noise test, vibration test, leakage test

Applications

Submersible pumps, deep well pumps, centrifugal pumps, pipeline pumps, self-priming pumps, chemical pumps, screw pumps, household booster pumps, sewage pumps, mixed-flow pumps, axial-flow pumps, vortex pumps, automotive washing pumps, automotive circulation pumps, automotive cooling pumps, etc.
