  Series / Parallel Pumps / PC

  The Pump Test Rig was developed for the serial and parallel operation of 2 centrifugal pumps. It is used predominantly for determining pump and system characteristic curves. The measured data is recorded electronically during the experiments. This makes it possible to display and process the data on a PC. At the same time, the measured data is displayed on easy to read digital displays. This allows operation without a PC connected. The test rig basically comprises 2 identical centrifugal pumps that are driven using DC shunt wound motors of adjustable speed. Proximity switches measure the speed of the motors, force transducers on the motor shafts determine the output torque. At all key points on the unit, the pressure is determined using absolute pressure transducers, the flow rate is measured using a magnetic-inductive sensor.

  Pump and Turbine Trainer

  Using the Basic Unit, Pump and Turbine Trainer, an extendable experimental concept for basic experiments in the area of hydraulic fluid-flow machines has been realised. Here the forms the basic unit. Equipped with a powerful centrifugal pump and a sealed water circuit with an own supply tank, the module can be used to perform experiments on pumps. Rotational speed, flow rate and back-pressure can be adjusted. The drive power of the pump is determined using the rotational speed and the torque. Modern electronic measuring instruments and digital displays for pressure, flow rate, torque and rotational speed are integrated into the basic unit. Easy to interchange sets with various types of water turbines enable the range of experiments to be expanded to include experiments on turbines

  Series / Parallel Pumps

  The series and parallel pump test rig is system that has been designed for instructional and experimental use in vocational schools, special colleges and universities. The series and parallel pump test rig can be used, for example, to clarify the differences between serial and parallel operation of two pumps. The test stand includes two identical centrifugal pumps that are driven by speed-controlled DC shunt motors. The speed of the motors is clearly shown on the switch box, together with the current and voltage. The motors are suspended. The driving torque is determined with a torque wrench. The pressure is measured on the intake and delivery side of the pump with manometers. The flow rate in the system is displayed by a water meter. It can also be determined by measuring the differential pressure at a nozzle or orifice.

  Multi-Pump Trainer

  The represents a closed system for training and experiments that is equipped with all the necessary measuring devices. The test rig is equipped with 4 pumps, provision is made for the installation of an additional pump of any type. The pumps fitted comprise 2 identical centrifugal pumps with adjustable speed DC shunt wound motors, a self-priming side channel pump with single phase AC motor, and a reciprocating pump with a single phase AC motor. Manometers on the suction and delivery side of the pumps indicate the relevant pressures in the system. The flow is indicated by a water meter. Volumetric flow rate measurement can be made using the stop watch included. The rotational speed of the drive motors is determined using a handheld tachometer. Current and voltage to the drive motors are indicated in easy to read form on the switch box associated with the test rig. The power regulator for controlling the speed of the DC motors is also to be found there. Torque is determined using a torque wrench with gauge; with the aid of the wrench a counter torque is placed on the shafts of the motors installed as pendulum mechanisms, the torque can then be read off. In this way the provides a wide range of measured data that makes it possible to address key problem areas in pump technology. Due to the closed water circuit and supply from an own
  tank, the test rig is independent of the water mains.
