Introducing a second pump to the hydraulics bench enables to study two pumps in series and parallel configuration. The module consists of a pump equipped with two pressure gauges and of an inverter. This enables to vary the number of pump rotations and to measure the absorbed power.
TRAINING PROGRAM:
• Drawing of the curve H(Q) for a centrifugal pump
• Plotting the curves of head, power, speed and efficiency versus flow rate
• Series connection of two pumps with same characteristics
• Series connection of two pumps
• Parallel connection of two pumps
