Multi-Pump Test Rig

The rig can integrate both rotodynamic and positive displacement pumps, and is supplied with the most common example of each type as standard.

This totally new system benefits from electronic instrumentation, optional data logging and the use of a state of the art sensorless vector drive to accurately determine the torque provided by the drive motors.

As an option the unit can be fitted with two identical centrifugal pumps to allow simple series/parallel pump configurations to be demonstrated.

Specification

• A self contained multi-pump test rig, containing all the services and instrumentation for determining the characteristic curves of different pumps at different speeds
• Contains five different pump positions (4 active)
• Centrifugal pump and gear pump supplied as standard.
• Axial pump, flexible impellor pump, turbine pump, diaphragm pump, piston pump and a second centrifugal pump are all available as accessories
• Series/parallel pump demonstations can be performed with the second centrifugal pump option
• Control valve incorporated upstream of each pump (except axial pump) to demonstrate the effect of suction loss on performance
• Electronic torque measurement using a state of the art sensorless vector drive
• Electronic measurement of flow, pressure head and suction
• Optional volumetric flow measurement system for reciprocating pumps
• Optional data logging and educational software.
