HM 283

Centrifugal Pump Demonstrator

Technical Description

The centrifugal pump demonstration unit / PC HM 283 is designed for instructional and experimental use at vocational schools, special colleges and universities. The model is part of a series of units that permit experiments to fluid-flow machines. The unit is set up on a stable base plate and includes a pump, tank, all required fittings and recording devices for flow rate, temperature, pump speed, intake and conveying pressure. The signals can be digitised and transferred to a PC via a data acquisition card. The following accessories are required for operation: interface module (HM 280.01), data acquisition card with software (HM 280.03) and set of connecting cable (HM 280.04). The power meter (HM 280.05) is a practical way to expand the unit, as it enables the user to determine the efficiency rate of the pump.

Learning Objectives / Experiments

In conjunction with the accessories the measured values can be processed and shown on a PC. The following experiments can be carried out:

Recording of characteristic pump curves
Determination of pump efficiency
Effect of speed on conveyed quantity and head

Features

Experimental set-up to determine characteristic pump values
Closed water circuit
Electronic recording devices
Data processing on a PC
