MULTI-PUMP TEST RIG

Multi-Pump Test Rig: MTFM-11

The equipment comprises a water reservoir and five pump positions (four active). Each pump position uses pipe work and sensors optimized to the type of pumps it is intended for. Positions 1, 2a and 2b are optimized for high flows at low heads, such as the rot dynamic pumps, whereas positions 3 and 4 are suitable for lower flows but higher pressures as obtained from the positive displacement pumps. Positions 2a and 2b are mutually exclusive as they share the same motor drive. Switching between any of the four installed active pumps is simple requiring only isolating valve changes and control panel selection.

Changing over an installed pump for one of the other options is still straight forward but requires plumbing changes topping up the tank with water and reprogramming some inverter settings.

A PC is used to set the required speed of the pump(s) on test. A separate mimic diagram for the selected pump(s) on test displays the important measured and calculated variables. The following table defines which types of pumps are available for each position.

Description
