Self-Priming Pump KGE Series

KGE Series

Self-Priming Centrifugal Pumps.

System Characteristics

The KGE is a self-priming centrifugal pump with radial (semi-open or closed) impeller, overhung mounted on a bearing pedestal. If a spacer type coupling is used, the pump can easily be dismantled without it being necessary to disturb the pipings or to move the motor.

The KGE series is available in different drive possibilities:

• KGE: pump with bare shaft for clockwise rotation.
• KGEL: pump with bare shaft for counter-clockwise rotation.
• KGEF: pump with flanged motor (close coupled)

Applications

The KGE is suitable for clean and polluted liquids, which are non-corrosive to cast iron, including water, oils, petrol and all kind of chemicals. Draining building excavations, emptying ponds, ditches and swimming-pools, water extraction for irrigation and watering, aboard ships as bilge, deck wash and general service pumps. Emptying pits and throughs containing wastewater, handling fuels, condensate extraction pumps.

Technical data –

• Casing : Cast iron Max. liquid temp: 95°C
• Impeller : Cast iron, Bronze
• Max. capacity : 100 m3/h
• Max. speed : 3 600 rpm
• Max. pressure : 8000 kPa (8 bar)
