FELUWA check valves in cassette design

Check valves rank among the key components of positive displacement pumps. With FELUWA MULTISAFE® double hose-diaphragm pumps and hose diaphragm piston pumps, the suction and discharge check valves are to be considered as the sole real wearing parts. For this reason, the achievement of utmost lifetime is paramount when designing the valves.

FELUWA check valves are individually adapted to the application, both with regard to flow velocity and the selection of material and flow geometry. They are of modular cassette design, which allows for the utilisation of ball or cone valve trims with the same valve casing.

The cassettes are hinge-mounted between the pump head and suction or discharge manifold, respectively. For maintenance purposes, the complete valve assembly is easily removable like a cassette by means of jacking bolts, without prior dismantling of adjacent elements or piping. Removal neither requires skilled personnel nor special tools. This allows for minimum downtime for service and maximum availability.
FELUWA valve casings are suitable for a great variety of valve trims. Ball valve trims are characterised by a considerably smaller number of parts than cone valves (3 vs. 7).
