The unit is composed by a piston pump mounted on a stainless steel basement and connected to a continuous circulation tank. The front part of the pump is in clear plastic to see inside. On the discharge pipe there is an adjustable back-pressure valve, a needle valve and a safety valve to protect the system from potential overpressures. An additional valve allows to include a pulsation damper in the circuit. The digital instruments allow to measure head and discharge pressure of 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.
