As an enhancement to the EcoPump HPE the Pressure Relief Valve prevents possible damages caused by unpredictable excess pressure. It is simply connected directly to the outlet of the pump. Protection against pressure peaks and improper use- e.g. closing ball valves is guaranteed. By using the optionally available sensor in the relevant port, the pressure relief valve is the perfect interface to allow full closed-loop functionality. Typical fluids include water and solvent borne paints, varnishes, enamels and lacquers.
