MIXED FLOW - drinking water - sewage water - cooling water A world of pumping experience

The Saturn mixed flow pumps are designed using CAD systems and specially developed computer programs for flow optimisation. This results in high efficiencies, low power consumption and reduced operating costs. Saturn mixed flow pumps are vertical (VMF) models with a variety of mounting arrangements and nozzle positions to suit most pipe configurations and pumping station design. Vertical pumps can be supplied with the motor mounted directly on the pump, or independently on a second floor or as a closed-coupled pump where the impeller is mounted directly onto the extended motorshaft. The pump...

By using oversized shafts and reducing the overhang, shaft deflection is reduced to a minimum. This eliminates shaft failures and increases packing life. The larger sizes of pumps are fitted with a double volute which reduces the radial and axial forces and increases bearing life. If it is necessary to disassemble the pump, the entire rotating assembly can be removed without disturbing the casing or suction and discharge piping. For larger capacities in sewage systems the mixed flow pumps have a specially designed impel- ler with large ball passages. The replacable wear rings carry solid matter...
