-- Capacity
Ranging from 100 to over 12,000 LPM capacity from deep tubewell of 150 mm to 500 mm diameter and up to 92 meters depth. Driven either by oil engine, or electric motor Conforming to IS:1710.
-- 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
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
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.
|
-- Lubrication
For oil lubricated turbine pumps, manual lubricator or automatic electric oil lubricator available. Separate pre lubricating tank is available for water lubricated turbine pump.
-- Suction Case
Made of closed-grained cast iron. Houses bronze bearing and sand collar which prevents entry of sand into suction case
bearing. Guides flow of water into the eye of the lowest impeller.
Casing Pipe / Line Shaft Tube
Made of steel. Concentrically threaded for line shaft bronze bearings provided at intervals of 1.5m.
Column Pipe
Made of steel. Concentrically threaded as per Indian standards.
Line Shaft
Made of high carbon steel. Concentrically threaded at both ends. The line shaft in oil lubricated pumps rotates in bronze bearing fitted at 1.5 m. intervals. The line shaft in water lubricated pumps has a stainless steel sleeve which rotates in cutless rubber bearing fitted in C.I. bearing retainer (spider).
Discharge Head
Robust construction. Has an integral smooth discharge elbow. In water lubricated pumps, the discharge head houses a stuffing box and gland nut. In oil lubricated pumps, it houses a tension nipple and gland nut. Standard discharge outlet flange is drilled as per IS specification.
Pre - Lubrication
For water lubricated turbine pumps, pre-lubrication tank and pipe connections with cock available for Pre-lubrication of pump shaft, bush bearings and stuffing box before starting the pumps.
VERTICAL TURBINE PUMPS with special material of construction can be supplied against specific requirement.
