The M 60 is a self-priming and smoothly running diaphragm pump used to deliver sea water. All parts which come into contact with liquids are made of bronze or stainless steel. The used rubber parts are oil-resistant. The pump is non-reactive to running dry and very suitable for continuous operation. The M 60 is equipped with flap valves which open all the way. Therefore it can convey bigger solids such as rags. The pump can be mounted in various ways, etc. lying, upright, above head or hanging. The delivery side can be adjusted from left to right, or right to left or from up to down and down to up. The fields of operation of the M 60 are on bigger yachts or in professional shipping as a hard-wearing bilge pump.
