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 ow backwards. In case pumps are
placed in parallel, the non-return valve also
prevents that 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.
3. Technical data
