These pumps find wide applications in water transfer, water supply, irrigation, agriculture, farms, sprinkler, domestic house hold requirements, building and construction and general industry. High efficiency, robust case construction of cast iron, impeller construction of bronze makes these pumps an ideal selection for applications that require easy-to-maintain, reliable, long lasting pumps.

Constructional features:

End suction, volute type with top centerline discharge. Suction and discharge nozzles as well as the supporting feet are cast integral with the casing.

Enclosed type dynamically balanced. Hydraulic balance is achieved either by back vanes for smaller impellers and by balancing hole with back wear rings for large impellers.

Three driving units cover complete range. The high tensile steel shaft accurately machined and ground is supported by anti-friction bearings. The shaft is protected by shaft sleeve from wear in stuffing box area.

Stuffing Box:
The stuffing box can be sealed by gland packing or by mechanical seal.

Deep groove ball bearings are provided. Standard lubrication is grease for smaller sizes.
Oil lubrication for higher sizes of pumps.

Direction of Rotation:
Clockwise viewed from driving end.

Suitable for coupling with electric motors, engines directly or through belt drive.

Standard: Drilling as per BS EN 1092-2 (DIN 2533 ND 16)

Drilling as per IS/BS/ASA/DIN available with suitable pressure rating.

The WN+/WNL+ is also available in a close coupled execution the WNC+ (OH1)
