Description of Series and Parallel Pump Test Set Unit:
The apparatus consists of a Hydraulics Bench, complete with Auxiliary Pump and Speed Control Unit and a Pump Speed Display Unit, enabling each pump to be run over its full speed range. The pumps concerned are identical centrifugal units and are mounted on the baseplate of the Hydraulics Bench and driven by individual motors, both of which have their own variable speed controller. The speed of the selected pump can be displayed individually on Pump Speed Display. Suitable associated pipework and valving arrangements are supplied to allow easy operation of both pumps in either series or parallel configurations. This allows the approximate doubling of discharge flow and head when operating in parallel and series modes respectively. Suction and delivery pressures can be varied by means of the inlet and outlet valves on the Hydraulics Bench and displayed on a bourdon pressure gauge. Flow measurement is measured via calibrated weir or stepped volumetric measuring tank supplied with Hydraulics Bench. A Wattmeter is included to measure the electrical input to the pumps.
