Horizontal centrifugal pumps
Centrifugal pump for highly aggressive media.
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.
Functional principle of horizontal centrifugal pumps
• 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).
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.
Advantages of horizontal centrifugal pumps
• 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.
