Vertical Shaft Turbine Pumps:

Be suitable to be used where a static suction lift is involved, can save pump room space too, but

cost is higher than other pumps, on site job and service is difficult.

Vertical turbine pump is suitable for well or pit or other low water level condition.

How It Works:

The vertical turbine pump is normally driven by an AC electric induction motor or a diesel engine

via a right angle drive. The end of the pump consists of a rotating impeller that is joined to a shaft

and guides the well water into a diffuser casing known as a bowl.

Pumps with multi-stage arrangements use several impellers on a single shaft to generate higher

pressure that would be required for pumping water from deeper wells or where higher pressure

(head) is required at ground level.

A vertical turbine pump works when water comes through the pump from the bottom through a bell

-shaped device known as a suction bell. The water then moves into the first stage impeller, which

increases the velocity of the water. The water then moves into the diffuser casing directly above

the impeller, where the high velocity energy is transformed into high pressure. The diffuser casing

also guides the fluid into the next impeller located directly above the diffuser casing. The process

goes on through all the stages in the pump.

The VTP pump line is normally designed to operate in wells or sumps. Its bowl assembly consists

primarily of a suction case or bell, one or more pump bowls and a discharge case. The pump bowl

assembly is positioned in the sump or well at a depth to provide the proper submergence.
