Key Features of Vertical Deepwell Turbine Pump

• Bowl made of close-grained cast iron. Houses bronze bowl bearing, S.S. impeller shaft & impeller. Has hydraulically profiled guide vanes for higher efficiency.
• Impeller is made of close-grained cast iron or bronze. Single suction, enclosed or semi-enclosed type. Dynamically balanced. Clamped by draw-out type collet and locknut to stainless steel shaft.
• Discharge case is made of close-grained cast iron. Houses bronze bearing. Guided water flow into column assembly. The discharge case in oil lubricated turbine pumps has intermediate bearing, lantern ring, asbestos-plated yarn seal [gland packing] and discharge case bearing for line shaft tube. Prevents water from entering the line shaft tube as the high pressure water is bypassed through relief ports in the lantern ring.
• The discharge case in water lubricated turbine pumps has a sand collar which prevents entry of sand into the discharge case bearing.
• For oil lubricated turbine pumps, manual lubricator or automatic electric oil lubricator available. Separate pre lubricating tank is available for water lubricated turbine pump.
• Irrigation in agriculture and horticulture from deep tubewell, openwell, canal and river water
• Lift irrigation
• Municipal water supply
