POSITIVE DISPLACEMENT PUMP MODULE

For use with and driven by the Universal Dynamometer (MFP100, available separately), the Positive Displacement Pump Module is part of TecQuipment’s Modular Fluid Power range. When used with one of the optional pumps, the Positive Displacement Pump Support Module is ideal for student experiments, demonstrations and projects. Positive-displacement pumps are common machines, used to move fluids in many applications, and usually at high pressures. They can be rotary pumps or reciprocating pumps and work by moving a fixed volume of fluid from their inlet to their outlet. These pumps are used in lubrication systems, hydraulic systems, automobiles, agriculture, medical equipment, sanitation and many industrial applications.

The module consists of a mobile frame with an oil reservoir, a flow meter, valves and instruments to measure pump performance. The flow meter is a positive displacement unit, so that it still works correctly at any oil viscosity. Any of the optional pumps fit to the module. Two flexible, high-pressure pipes with quick-release, self-sealing connections connect the pump to the oil circuit.

The separate Universal Dynamometer (MFP100) also fixes to the module to drive the pump. The Universal Dynamometer measures and displays the speed and torque of the pump to calculate and display mechanical (shaft) power. Electronic pressure transducers measure the pump inlet and delivery pressures and the fluid flow rate. Speed is fully variable up to the maximum allowable for the pump. Included with the module is the oil to fill the oil reservoir. A thermocouple measures the oil temperature to allow calculation of the oil viscosity. The oil system includes a pressure-relief valve to keep the oil pressure at a safe level.

The optional positive-displacement pumps include rotary and reciprocating types, including a piston pump, a gear pump, a vane pump and a swash-plate (axial piston) pump. The optional pumps fix to the bottom shelf of the pump-support module when not in use.

For quick and reliable tests, TecQuipment can supply the optional Versatile Data Acquisition System (VDAS®). This gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer.
