The Bench VP-P/EV is a table-top educational unit for the study of the technical characteristics of volumetric piston pump.
The measurements, which can be performed varying the operation conditions, can be easily compared with data resulting from the theory.
The group is supplied with a manual which describe all parts of the unit, the installation and utilisation procedures, as well as many exercises with their results.
Measurement of flow rate and pressure at different operation conditions
Regulation of the flow rate at the variation of the volume
Efficiency of the pump
Verification of the employment of a vibration damper
Verification of the safety system with calibrated valve
The reciprocating pump fitted with the bench is micrometrically regulated by the piston upstroke; this allows to change the volume of the pumping chamber and consequently to modify the delivered capacity without reducing the delivery pressure. The unit is completely self-sufficient and it is fitted with a wheeled frame; the working liquid is oil. The unit includes:
Trolley mounted frame
Feeding and collecting tank: capacity 50 l
Piston pump: max flow rate 62 l/h, power 0.18 kW (0.25 HP)
Manometer (0 to 10 bar)
Simple calibrated tank to measure the delivered capacity
