Standard Design Features Of The Vertical Turbine Pump(VTP)

The bowl assembly is the heart of the Vertical Turbine Pump(VTP) . The impeller and diffuser type casing are designed to

deliver the head and capacity that your system requires in the most efficient way possible. The fact

that the Vertical Turbine Pump(VTP) can be multi-staged allows maximum flexibility both in the initial pump selection and in

the event that future system modifications require a change in the pump rating. Submerged

impellers allow pump to be started without priming.

A variety material options allows the selection of a pump best suited for even the most severe

services. The many bowl assembly options available assure that the Vertical Turbine Pump(VTP) satisfies the user's need

for safe, efficient, reliable and maintenance-free operation.

1. Strainers

316SS Basket strainers to provide protection from large solids.

2. Suction bell

Allows smooth entry of liquid into impeller eye, minimizes vortex formation.

Scotchkote custom fusion bonded epoxy coating inside.

3. Suction bell bearing

Provided for shaft stability.

4. Sand collar

Prevents solids from entering suction bearing.

5. Impeller

Hydraulic balancing to reduce axial down thrust and achieve long thrust bearing life.

Dynamic balancing of impellers are available.

6. Pump shaft

Heavy duty, 416SS standard, other alloys for strength and corrosion resistance.

Hollow pump shaft with flushing hole special for bearing flushing on corrosive/abrasive services.

7. Diffuser bowl

Available in variety of cast material. Scotchkote custom fusion bonded epoxy coating inside to

improved the efficiency and longer life. Registered fits assure positive alignment, ease of

maintenance.

8. Sleeve type bearing

Provided at each stage to assure stable operation away from critical speed.

9. Wear rings

Dual wear rings for enclosed impellers and bowls, permits re-establishing initial running

clearances and efficiency at lower cost. Hard facing of wear surface available for longer life.

Wear ring can be flushed when solids are present in the pumping liquid.

10. Keyed impeller

Keyed impeller for all the pumps, suitable for pumping liquid in high temperatures. Keyed

impellers provide ease if maintenance and positive locking under fluctuating load and

temperature conditions.

11. Flanged column

Heavy duty seamless column pipe sections are provided with flanged ends incorporating

registered fits for ease of alignment during assembly.

12. Lineshaft and coupling

a. Open lineshaft

Flanges column/product lubricated lineshaft is recommended for ease of maintenance or

whenever a special bearing material is required. Precision keyed lineshaft coupling available in

all sizes for ease of maintenance. Various bearing material available. Renewable shaft sleeve

or hard facing of shaft available for longer life.

b. Enclosed lineshaft

The lineshaft is protected by water flushing tube, flushing water for bearing and wear ring on

corrosive/abrasive services.

13. Bearing retainer and lineshaft bearing

Ductile cast iron bearing retainer for size smaller that 24” . Various bearing material available.

14. Discharge head and motor riser

Discharge head and motor riser designed for all modes of drivers including hollow shaft or

solid shaft motors, right angle gears, vertical steam turbines, etc. Fabricated elbow discharge

head engineered to minimize losses. Large access holes provide easy access to coupling and

stuffing box. Above ground and below ground discharge head for requirement.

15. Thrust bearing

Oil lubricated thrust bearing assembly set with water cooling system make the pumps running

safely in longer life.

16. Packing box

Whenever packing lubrication leakage can be tolerated and the discharge pressure does not

exceed 300psi, a packed box may be used. Optional headshaft sleeve available to protect shaft.

17. Coupling for pump and motor

Flexible coupling for pump and motor when pump with thrust bearing, impeller adjustment by

the nut on the top shaft.
