quick overview :
The unit is composed by two centrifugal pumps mounted on a stainless steel basement and connected to a continuous circulation tank. The pumps can be configured for single, in series and in parallel operation by adjusting the valves mounted on the pipes. The front part of the pump is in clear plastic to see inside. The suction and discharge pipes are transparent too and each one has a flow control valve. It has two interchangeable impellers, a forward curved impeller and a backward curved one, in order to compare their
performances. The digital instruments allow to measure suction and discharge pressure to the pump, as well as flow rate and water
temperature. The pump speed is accurately controlled by an industrial inverter within the interface console (necessary accessory) and also indicates torque and power consumption. The interface console also has a data acquisition software (PC not included) to study the values of the parameters measured by the electronic instruments.
