Series And Parallel Pump Test Bench With Torque And Speed Measurement

Series And Parallel Pump Test Bench With Torque And Speed Measurement

Teaching Objectives of

• Study of the pumps alone, in series and in parallel modes.
• Determination of the characteristic curves (suction and discharge).
• Study of the relation flow/pressure.
• Study of the influence of the suction height.
• Influence of the rotational speed on the flow.
• Measurement of the electric power absorbed by a pump.
• Measurement of the mechanical power absorbed by a pump.
• Calculation of the efficiency of a pump.
• Demonstration of the cavitation phenomenon.

Technical specifications

• A centrifugal pump with stainless steel body, power 0.55 kW
• A second centrifugal pump to study the coupling of the pumps in series or parallel

Five pressures measurements:
