One-or two-stage, non self-priming centrifugal pump, with axially split pump housing. The pump housing is spiral-shaped and consists of two cast iron parts, which are joined together by means of screws along the pump axis.
Impermeability between the flanges of the two parts of the pump housing is achieved by using a paper gasket.
The system is alternatively delivered as a
- Complete unit, comprising a pump with semi-elastic coupling, coupling guard and motor on a common baseplate
- Pump with semi-elastic coupling, coupling guard on a baseplate
- Pump with bare shaft end, without baseplate
Application
Axially split case pumps are primarily used in areas associated with water supply, water circulation, water injection, spray ponds, air-conditioning, water purification, sprinkler systems, drip irrigation, fire fighting etc.
Special features/product advantages
- Efficient hydraulics for high flow rates up to 17,000 m³/h
- Low NPSH thanks to double suction impeller
- High process reliability and easy maintenance without removing the pressure or suction lines
- Decreased noise level and reduced vibrations
- Options: Drinking water approval (KTW, ACS), innovative Ceram CT coating
