Plunger Pump Demo Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14192

Overview

The Plunger Pump Demonstration Apparatus is a compact and comprehensive unit designed to study the principles, operation, and performance characteristics of a reciprocating plunger-type positive displacement pump.

It features a motor-driven plunger pump mounted on a stainless steel base, complete with a water reservoir, pulsation damper, control valves, and interconnecting pipework — forming a self-contained circulating system.

A transparent acrylic pump head and components allow direct observation of the suction and delivery strokes, fluid displacement, and pulsation effects. The system includes sprung and needle loading valves to demonstrate different flow and pressure characteristics, while a pressure relief valve ensures safe operation.

For advanced study and data analysis, the apparatus is equipped with electronic sensors for measuring cylinder pressure, plunger position, outlet pressure, and cumulative flow, and can be connected to a PC via an interface console (optional). The dedicated software provides tools for data acquisition, processing, and real-time graphical display.
