NiYo Engineers’ Gear Pump Test Rig is a training equipment that helps understand design and operation concepts of positive displacement oil pump, especially a gear pump.
This is a recirculating type pump test rig. Since this is a positive displacement pump, a special relief valve arrangement helps varying flowrate of the pump without compromising on safety aspect. Pump study is carried out by varying discharge flow rate, pressure and pump speed. Pressure, flow rate, power input to the pump and pump speed are measured. Based on these data performance characteristics of the pump is plotted.
