Unit designed to demonstrate the operational advantages of parallel or series operation, depending on the required duty.
This unit consists of two centrifugal pumps, a water tank and circulation pipes with valves at the inlet and outlet of the pumps, three pressure meters and a flow meter. The centrifugal pumps can operate: alone, coupled in series or in parallel. A three-phase motor activates a pump with possibility of adjustment and measurement of the turn speed as well as of the transmitted mechanic torque.
The pumps are installed in a pipes system, which, as it is a closed circuit, avoids the permanent waste of water during the operation. By the appropiate positioning of the valves it is possible to connect the pumps individually, in series or in parallel, depending on which test is going to be performed.

2 Centrifugal pumps:
One is a three-phase pump of 0.37 KW with continuous speed adjustment with inverter of frequency/voltage and the other one is singlephase.
3 valves that allow connecting the pumps separately in series or in parallel by the appropiate positioning of the valves and 2 regulating valves.
Discharge pressure meter (0 to 2.5 bar).
Discharge pressure meter (0 to 6 bar).
Admission pressure meter (-1 to 0 bar).
Flow meter, range:0 - 150 l./min.
The speed of one pump is adjustable from speed controller.
Water tank, capacity: 60 l.
