CombiBloc is the premier solution for pumping clean thin liquids in a very
cost-effective way. The pump is part of SPX 's Johnson Pump 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.

General industry
The 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.
shipbuildinG
CombiBloc 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.
utility
Applications 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.
horticulture
In horticulture the CombiBloc is used as a transport pump for hot water heating systems.
From know-how to
finding solutions
Typical product applications
CombiBlocHorti is an End Suction close coupled pump with
extended shaft as an modulair variant within the combi range for
horticulture applications.
