 HL 107 Circulating Pumps Training Panel
 Technical Description

The trainer contains a pipe system with two circulating pumps. It is possible to switch between series and parallel operation using ball valves.

Two rotameters with different measuring ranges are provided for the measurement of the flow rate. Manometers indicate the pressure at all relevant points in the system. The temperature can be read on a bimetallic thermometer.

The trainer has a closed water circuit with expansion vessel and is thus independent of the water mains.

Learning Objectives / Experiments

- Pump characteristics at varying speeds
- Determination of pipework characteristics
and operating points
- Series operation of circulating pumps
- Parallel operation of circulating pumps
- Comparison of experiment and calculation

In conjunction with other training panels in the HL 100 series, it is possible to set-up a complete heating system.

 Features

* Trainer on heating systems and plumbing1
* Function of circulating pumps, series and parallel

operation1
* In conjunction with other trainers in the

HL 100 series, assembly of a complete heating

system is possible
