DEMANDS INFO FORM Kathy.pdf
Vertical shaft turbine (commonly referred to as “vertical turbine”) pumps are unique in that the impellers are intended to be submerged in the water source. They are used for installations where the water source is below the pump impellers.
These pumps have a bowl assembly which contains several impellers on a vertical shaft – where the discharge of one impeller directly feeds the suction of the next impeller, and so on – a column assembly built to a specified length, and a discharge head assembly which holds the motor or right-angle gear drive. In a mechanical room, the discharge head assembly of a typical vertical turbine pump is the only visible part of the pump.
This pump does come with a few disadvantages. Besides the additional initial cost, these pumps can be challenging to service. One must remove the pump or disassemble it, which often requires use of a roof hatch in a room so that a crane can lift it out for examination. Since these pumps are all custom-built, the lead times can also be long – from 8 to 20 weeks depending on the manufacturer and models.
Special care must be made before operating a vertical turbine pump for the first time – the shaft and impellers must be properly adjusted to lift them off of the bowl casings prior to operation.
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.
