Your choice of any pump should be a well considered act, not to be left to pure chance. Your choice of a DESMI self-priming centrifugal pump holds out the advantages of versatility and sturdiness. Once the pump casing has been filled with water, the pump will be self-priming, i.e. it will automatically remove the air in the suction pipe using the diffuser principle. Another feature is the ability of the pump to carry impurities and solids along with the actual fluid. This is due to the open impeller design including a replaceable wear plate, as distinct from closed impeller design of other centrifugal pumps. The pumps is used for many applications, for example: • Bilge pumps • Ballast pumps • Fire pumps • Cooling water pumps • Wash-deck pumps • Fuel pumps • Wellpoint pumps • Irrigation pumps • Circulation pumps • Etc.

Open impeller design Semi-open, non clogging high efficiency impeller allowing the pump to operate on dirty water. Replaceable wear plate To keep the pump at max. capacity even after working with abrasive fluids for a long time, the tolerance between impeller and wear plate may be adjusted by way of shims behind the replaceable wear plate. Mechanical shaft seal A reliable, spring-loaded, mechanical shaft seal ensures rapid suction, and shaft wear and stuffing box tightening are avoided. Check valve mounted at a high level The pump check valve is mounted well above the impeller inlet. Consequently,...
