Constructional features:

Pump Casing:
Horizontal axially spilt volute type, suction and discharge nozzles and supporting feet are cast integral with lower half casing.

Double or single suction type accurately balanced. In case of double suction impellers, the hydraulic thrust is balanced automatically because of pressure equalization on both sides of the impeller.

The high tensile steel shaft accurately machined and ground is supported by antifriction bearings. The shaft is protected by shaft sleeves from wear in stuffing box area.

Stuffing Box:
Can be sealed by gland packing or by mechanical seal and is suitable for liquids having temperature from -10°C up to 90°C.

Grease Lubricated deep groove ball / roller bearings are provided. Large pumps can be provided with Oil Lubricated / Oil ring bearings.

Direction of Rotation:
– Standard: Anticlockwise (ACW) when viewed from driving end.
– Optional: Clockwise (CW) when viewed from driving end.

Suitable for coupling with electric motors, engines or steam turbines either directly or through belt drives, gear boxes etc.
