Non-self-priming, single-stage in-line centrifugal pump with axially split housing and double-sided suction impeller for installation on a base frame.
Sealing between the two parts of the pump housing is achieved by means of a paper gasket.
Shaft sealing is ensured with a flushed mechanical seal or with a cooled stuffing box packing.
The system is optionally delivered as a
– Complete unit, comprising a pump with semi-elastic coupling, coupling guard and motor on a common base frame
– Pump with semi-elastic coupling, coupling guard on a base frame
– Bare shaft pump, without base frame
Utilisation
– Raw water intake, pressure boosting and general transport in power plants, waterworks and municipal drinking water supply networks
– Cooling water and industrial water supply in power plants and industrial facilities
– Irrigation in professional irrigation/agriculture
– Pumping of heating water (in accordance with VDI 2035 Germany) and water-glycol mixtures
Special features/Product advantages
– Reliable continuous duty for an efficient drinking water supply over extensive piping networks – can be tailored to suit your exact requirements
– Reduced energy costs through high overall efficiency
– Simplified and shorter alignment process thanks to tolerant coupling (option) and motor adjusting device
– Increased operational reliability thanks to quiet-running hydraulics with lower vibrations and reduced noise level
– Reduced cavitation tendency through optimised NPSH performances
– Lower space requirements due to compact design
– Also available as certified drinking water version – optionally with Ceram CT coating also approved for drinking water
– Optionally available with Ceram CT coating – for an efficiency increase of up to 3 %
– Maximum volume flow of up to 4500 m³/h
