Non return valves for APP pumps
Products shown: 5
VCM 22
The function of the non-return valve to be mounted directly on the outlet of the APP pump is to protect the pump by allowing flow out of the pump while blocking flow into the pump. The valve incorporates a conical poppet design, which ensures sealing when used with a low viscosity medium such as water. Typically used in connection with APP 21 - 30 and APP 22 pumps.
VCM 92
The non-return valve is designed for use in Seawater Reverse Osmosis (SWRO) membrane systems. In case the high-pressure pump stops momentarily, the volume of water in the membrane vessel may work as an accumulator and will send flow backwards. In case pumps are placed in parallel, the non-return valve also prevents water from one pump runs into the parallel-coupled pumps at start-up. The function of the valve is prepared for easy installation on the high-pressure outlet. Typically used in connection with APP 53 - 92 pumps.
