CombiBloc

Close-coupled centrifugal pumps

SPX has many years experience in designing,

manufacturing and maintaining self-priming

centrifugal pumps for contaminated liquids.

CombiBloc is the premier solution for pumping clean thin liquids in a very
On the basis of this experience, the FreFlow cost-effective way. The pump is part of SPX 's Johnson Pump Combi-system,

to the design ensuring easy operation and CombiBloc represents a range of horizontal centrifugal pumps close-coupled
amazing reliability. 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.

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
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.
