Computerized Reciprocating Pump Test Apparatus
Product Code : EL-TMLE-10688
Computerized Reciprocating Pump Test Apparatus (code EL-TMLE-10688) is an experimental unit for demonstrating the operating behaviour and important characteristic variables of piston pumps. A piston pump with variable speed of 30–180 min-1 via frequency converter, delivering up to 135 L/h at a maximum head of 40 m, works in a closed water circuit with an air vessel, and its sensors send data via USB to a PC with the included software.

What Is the Computerized Reciprocating Pump Test Apparatus Used For?
A reciprocating pump draws water into its cylinder as the piston moves back and pushes it out as the piston moves forward, so the delivery pulsates with each stroke. Students run the pump at speeds from 30 to 180 min-1, set the flow and head with the needle valve and overflow valve, and watch the piston through the transparent housing while the cylinder and outlet pressures and the crank angle are recorded. The software draws the p-V diagram of the intake and discharge cycle, the delivery and cylinder pressure curves and the pump characteristics, and the influence of the air vessel on pulsation damping can be studied.
What to Specify When Ordering
- Quantity — the number of reciprocating pump units required.
- Power supply — 230 V, 50 Hz, 1 phase, or the 230 V, 60 Hz or 120 V, 60 Hz, 1 phase version.
Frequently Asked Questions
What is the p-V diagram used for here?
Pressure inside the cylinder is plotted against cylinder volume, found from the piston rod angle sensor, so the intake and discharge of water in each cycle can be seen clearly.
What are the pump and drive ratings?
The piston pump runs at 30–180 min-1 through a gear transmission ratio of 1:7.5 from a 180 W drive motor, with a maximum flow rate of 135 L/h and a maximum head of 40 m.
How is the pulsating delivery damped?
An air vessel in the circuit damps the pulsating pressure curve of the pump, and the influence of this pulsation damping is one of the experiments.
Which sensors are fitted?
One pressure sensor measures at the pump outlet and another inside the cylinder, both over 0–5 bar, and an angle sensor follows the piston rod over 0–360° of crank angle.
How is the data recorded?
Microprocessor-based measuring technique, protected in the housing, transmits the measured values directly via USB to a PC, where they are analysed with the included software.
Which supply versions exist?
The unit runs on 230 V, 50 Hz, 1 phase, and versions for 230 V, 60 Hz, 1 phase and 120 V, 60 Hz, 1 phase are also listed.
