Piston Pump Test Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14188

Overview

The Piston Pump Test Apparatus is an advanced training system designed to demonstrate the working principle, performance characteristics, and operating behavior of a positive displacement piston pump. The unit features a closed water circuit equipped with a variable-speed piston pump, a transparent water tank, and an air vessel for pulsation damping.

Piston pumps are characterized by their ability to generate high pressures at low flow rates, with the flow rate being largely independent of the delivery head and dependent only on pump speed. This apparatus allows the study of these characteristics through direct observation and quantitative analysis.

The transparent pump housing enables clear visualization of the piston movement and water flow during both suction and delivery strokes. The cycle of operation can be graphically represented on a p-V (pressure-volume) diagram. The system incorporates a needle valve for flow adjustment and an overflow valve to control the delivery head.

For accurate measurements, the unit is equipped with pressure sensors, a flow sensor, and an angle sensor to determine the piston position and corresponding cylinder volume. Data is captured using a microprocessor-based measuring system, and the results are processed and visualized through dedicated software via USB interface.
