Horizontal centrifugal pumps JP-840

These horizontal centrifugal pumps are operated by a direct-drive motor (max. 3.000 rpm). They are especially suitable for a fast transfer of chemicals when emptying containers or tanks as well as for applications when a
medium has to be pumped in circulation.

The JP-840 series offers several pump sizes with flow rates from 6 to 75 m³/h and head from 7,2 to 38 m. Their special construction with an open-impeller allows even the pumping of extremely dirty liquids or media containing small solids.

The maximum viscosity for these centrifugal pumps is 500 mPas (at 20°C) and the maximum temperature of the medium 65°C at PP or 95°C at PVDF. Depending on the application there are two versions available with different internal seals (lip seal or bellow-type seal).

The availability of different materials of construction – depending on chemical and thermal resistance of medium or environment – guarantees an absolute reliability of operation and a long life time of pump.

The flow rate refers to water at 18°C and was measured at the pump pressure port.

Pump principle


The impeller is connected over the shaft with the direct-drive electric motor. It rotates at a preset speed and produces a centrifugal effect (suction on the inlet and discharge on the outlet).



High chemical and thermal resistance.

Space saving and robust construction.

Suitability for continuous operation.

Weldless construction and therefore absolute reliability of operation.

Sealing via lip seal or bellow type seal.

Applicability even with extremely dirty liquids or media containing small solids.

Quick and easy maintenance.

Inexpensive spare parts.
