CSW Type

Typical Applications

Closed impeller water pumps for application in municipal water and wastewater, industrial wastewater treatment and food processing

Standard Design

All parts except the casing suction cover and impeller are completely interchangeable within a given frame group. Eighteen pump sizes are built on only five power frames. Maximum interchangeability helps reduce stock holding and assists with maintenance planning.

Stuffing Box Design

A universal stuffing box type is provided which will accept either a packing or mechanical seal.

Wear Plate  

A replaceable suction cover wear plate comes standard.

Tapered Shaft  

The impeller end of the shaft and the impeller bore are designed with a taper for reliability and ease of maintenance.

Impeller Nut

A contoured stainless steel nut is provided to prevent material from hanging up. The nut is secured by a stainless steel set screw.

Rear Pull-out Design

The complete rotating element can be removed from the pump without disturbing the suction or discharge piping. Fewer crafts are required to service the pump.


Either clockwise or counter-clockwise rotation can be supplied. The discharge nozzle can be arranged in any one of five positions for either rotation to suit the piping arrangement.

Engineered for Dependability

Constructed with two vane non-clog impellers with smooth water passages capable of passing soft solids without clogging.

Maximum Shaft and Bearing Life

Large diameter shafts minimise deflection and increase packing life.

Bearings are selected in accordance with the Anti-Friction Bearing Manufacturers Association (AFBMA) to provide for maximum life expectancy.

Simple Impeller Adjustment

Axial clearance between the impeller and suction cover is controlled by adding or removing shims between the outboard bearing cartridge and the frame.

Coupling Guards

Manufactured to NOSA (Occupational Health and Safety) specifications.
