Vertical Turbine Pump

Vertical turbine pumps are adapted for use in cased wells or where the water surface is below the practical limits, where

other pumps cannot do the same job.

Vertical turbine pump efficiencies are comparable to or greater than most centrifugal pumps.

The vertical turbine pumps have three main parts: the head assembly, column assembly and the pump bowl assembly.

The shaft and column assembly provides a connection between the head and pump bowls. The line shaft transfers the

power from the motor to the impellers and the column carries the water to the surface. The line shaft of a turbine pump may

be either water lubricated or oil lubricated.

The oil lubricated pump has an enclosed tube in which oil is lubricating the bearings. The water-lubricated pump has an

open shaft. The bearings are lubricated by the pumped water. If there is a possibility of fine sand being pumped, select the

oil lubricated pump because it will keep the sand out of the bearings. If the water is for domestic or livestock use, it must be

free of oil and a water lubricated pump must be used.

Permits the axial positioning of the impellers in thebowls at the end of the installation.

2. Head Shaft

The upper shaft, that transfers the power fromthe motor to the lineshafts.

3. Thrust Assembly

The axial loads are taken by bearings fittedin this assembly. VHS motors have this in itselfbut for VSS motors, a special assembly isused which is designed by VERSA.

4. VHS / VSS Electric Motor

Electric motor supplies the needed power, andhas various speeds and protection classes.

5.1 Intermediate Part

It is used with VSS motors only for the thrust assembly.

5.2 Elastic Coupling Pair

To transfer the power from the motor to the head shaft, couplin gs areused for VSS motor applications.

6. Discharge Head

The discharge head dimensions are directly related to pump capacityand column pipe.

7. Prelube Pipe

To avoid the dry working of the lineshafts in the first run, pre-lubricationcan be done through this pipe from an outer source.

31. Adjusting Nut

In the pump assembly, bowls, suction and discharge caseshave slide bearings. Bearings are sized according to the shaft diameter,speed and the pumped fluid. Metal-Rubber, only metal or onlyrubber designs can be applied.

Threaded or flanged discharge cases connect the pump assemblyto the column assembly.
