FEATURES
- The back pull-out design enables removal of the motor, coupling, bearing housing and impeller without disturbing the pump housing or pipe work.
- These are single stage, single suction, and horizontal shaft type pumps. The pumps are available to operate at 1450 rpm and 2900 rpm at 50 Hz.
- The pump casing is end suction, volute type with top centerline discharge. Suction and discharge nozzles as well as the supporting feet are cast integral with the casing.
- Impeller is 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.
- Shaft is made of high tensile steel accurately machined and ground is supported by anti friction bearings. The shaft is protected by shaft sleeve from wear in stuffing box area.
- The stuffing housing can be sealed by gland packing or by mechanical seal.
- Deep groove ball bearings are provided. Standard lubrication is grease.
- Direction of rotation is clockwise viewed from driving end.
- The pumps are suitable for coupling with electric motors, engines directly or through belt drives.
- Available in bare shaft pump, motor coupled pump and close coupling z type pump design.
APPLICATIONS
- Circulation of water in industries, air conditioning plants, power stations, mine water, lift irrigation, sprinkler systems, booster services, pumping brines, oils etc.
- Drip irrigation, water supply and building services.
- Condensate handling, fire fighting systems, environmental.
- Hot and cold water circulation, cooling water circulation.
- Thermic fluid, jet dyeing, volatile fluids.
- Corrosive and abrasive process chemicals like acids, alkalis, solvents, slurries, hydrocarbons, crystallizing liquids, nitric, ammonia, phosphate, chemical effluents etc.
- Chemicals, petrochemicals, refineries, sugar, paper, laminates.
- Industries, rubber, handling of hydrocarbons, organic and inorganic chemicals, dm water, food industries, salt, textiles etc.
