API 610 VS4 Vertical Turbine Long-shaft Under-water Liquid Chemical Pump
Single stage, single suction vertical pump. Absorbed advanced overseas technology, according to market demands, the new type energy conservation and environmental protection products were designed and developed independently. Pump shaft is supported by casing and sliding bearing. The submergence can be 6m, chart can cover the whole range of pump with capacity up to 400m3/h, and head up to 100m. Liquid can be available for various clean or contaminated fluids.
Submergence Up to 6 m
Widely used for
neutral or erosive liquid, liquid clean or with solid
Especially for Sewage treatment, cement plant, power plant, petrochemical and so on.
Why choose it?
√ New hydraulic mould improves pump efficiency
√ New and reliable shaft connection method
√ Particular balance cavity structure
√ Packing seal and flush pipe structure
√ New material and new crafts, improves reliability of pump
√ Prolongs maintenance and operation period

Packing Seal:
Although there is no pressure at suction and discharge, in case of overpressure of flush fluid to splash to the air from the base, soft packing must be used.
Shaft connections:
Long shaft is machined in two sections or more, end of one shaft screwed rod, the other one is machined with inner screw, two shafts are connected with screws, outside fixed with joint key and shaft bush. Torque is transferred by joint key, thrust force is transferred by screwed rod, this improves coaxiality of the pump shaft, at the same time, make it more easier of machining the long shaft.
Support type:
LY series pumps are adopted multiple points support, angle-contact ball bearing is used above the liquid, every short shaft under liquid is supported by sliding bearing, sliding bearing is fixed on the middle supporter, with which supporting pipes are connected.
Balance housing structure:
Balance housing is made up of pump casing and middle supporter, there is balance
pipe at the bottom of the housing to connected to the air, for releasing pressure and
reducing thrust force of the pump set. At the same time, solid liquid can be passed through the balance pipe to prevent solid liquid leakage up from entering sliding bearing. Under the lower sliding bearing, there is packing seal to prevent solid liquid leakage up again.
