Multiâ€Pump Test Rig Description and Specifications for Lab Tenders
Multiâ€Pump Test Rig.
1] Selfâ€contained mobile unit consisting of four different pumps and measurement instrumentation. [2] Supplied with a DC dynamometer, sump tank, volumetric tank and interconnecting pipework and valves. [3] Instrumentation includes torque measurement, tachometer with analogue readâ€out. [4] Bourdon gauges to measure delivery pressures. [5] Bourdon vacuum gauge to measure suction at pump inlet. [6] GRP volumetric tank with low and high flow ranges. [7] Knife edge weirs for flow measurement. [8] Basic unit includes the following four pumps: centrifugal pump, turbine pump, axial flow pump, gear pump. [9] Speed range 0 to 3000 rpm [10] Torque measurement 0 to 1Nm and 0.5 to 3.5Nm dual range. [11] Variable speed control by DC thyristor controller.
