Multi-Pump Test Set
TecQuipment's Multi-Pump Test Set unit consists of a water tank, pipework, suction and delivery throttle valves, AC dynamometer and quick-release couplings to support a wide range of pump types.
VDAS® Onboard provides data acquisition including:
• Suction and delivery pressure
• Flow rate
• Dynamometer torque and speed
Detailed investigation of rotodynamic and positive displacement pumps may be performed with this multi-purpose yet hydraulically self-contained test bench. It requires a single-phase electrical supply and a source of water.
The following pumps can be tested on this unit and are available as optional extras:
• Positive displacement gear pump (H85a)
• Positive displacement piston pump (H85b)
• Rotodynamic centrifugal pump (H85c)
• Rotodynamic axial pump (H85d)
• Positive displacement vane pump (H85e)
• Positive displacement lobe pump (H85f)
• Rotodynamic channel impeller (H85g)
The testing of such a wide range of pumps on a single test unit is made possible by the provision of quick-release hose and drive couplings, enabling changeover to be made easily and efficiently.
Torque measurement for the dynamometer is by load cell, whilst speed measurement uses a magnetic-type pick-up. Pump suction and delivery heads are monitored by pressure transducers and the flow rate in the circuit can be determined using the built-in flow meter.
The H85V test set features VDAS® Onboard for data acquisition
