CombiBloc Centrifugal Pump- Brochure

CombiBlocClose-coupled centrifugal pumpsCombiBlocCombiBloc is the premier solution for pumping clean thin liquids in a very cost-effective way. The pump is part of Johnson Pump’s Combi-system, a modular programme of single stage centrifugal pumps with a high degree of interchangeablility of parts between the different pump constructions.CombiBloc represents a range of horizontal centrifugal pumps close-coupled to electric motors. The pump is suitable for handling low-viscositty, clean or slightly contaminated and aggressive liquids. Characteristic of the CombiBloc is the compact configuration of the pump and the electric motor assembly. The use of a stub shaft allows standard IEC electric motors to be used. Thanks to the small number of components and the use of a mechanical seal, the CombiBloc requires little maintenance. This is further supported by Back Pull Out of the rotating assembly. The CombiBloc has applications in crop farming and market gardening, on board ships and in handling various chemicals.Technical dataMax. capacity 850 m3/hMax. head 105 mMax. working pressure 10 barMax. temperature 120 °CMax. speed 3600 rpmTest bed SPX Process Equipment NL in AssenFrom know-how to finding solutionsThe CombiBloc can be applied as a general duty pump in many industrial applications. Because of its economic features and ease of construction this pump is also ideally suited for space saving OEM skid mounting. General industry ShipbuildingCombiBloc pumps can handle both clean and slightly contaminated fresh water and sea water. Their compact, space saving build makes them ideal pumps for engine rooms and general duty.UtilityApplications of the CombiBloc within utility buildings are as general duty pumps, circulation pumps in heating and air-conditioning systems and pumps in water purification plants.HorticultureIn horticulture the CombiBloc is used as a transport pump for hot water heating systems.
