TRU2O Vertical Turbine Pumps

the hydraulic design of the pump bowl assembly. Using a new techniques in turbine pump design. It covers a wide range of hydraulic conditions

｡｡｡｡

Model OVTC

Vertical Industrial Turbine Pumps OVTC series is a single or multistage pump with

enclosed type impeller, designed for high pressure services.

High Capacity Vertical Turbine PumpsOVTM series is a single stage pump with

semi-open or enclosed type impeller, designed for high capacity, medium to high head services.

Low Head Vertical Turbine Pumps

VTA series is a single stage pump with axial-�ow impeller, designed for high capacity, low head services.

Right Angle Gear Box Driven Vertical Turbine Pumps VTG series is vertical turbine pump designed for engine driven through a right angle gear box, for the place where electric power is not available services.

The bowl assembly is the heart of the 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 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 VTP satisfies the users need for safe, efficient, reliable and maintenance-free operation.

1. Strainers316SS Basket strainers to provide protection from large solids.

2. Suction bellAllows smooth entry of liquid into impeller eye, minimizes vortex formation. Scotchkote custom fusion bonded epoxy coating inside.

3. Suction bell bearingProvided for shaft stability.

4. Sand collarPrevents solids from entering suction bearing.

5. ImpellerHydraulic balancing to reduce axial down thrust and achieve long thrust bearing life. Dynamic balancing of impellers are available.

6. Pump shaftHeavy duty, 416SS standard, other alloys for strength and corrosion resistance. Hollow pump shaft with �ushing hole special for bearing �ushing on corrosive/abrasive services.

7. Di�user bowlAvailable in variety of cast material. Scotchkote custom fusion bonded epoxy coating inside to improved the e�ciency and longer life. Registered �ts assure positive alignment, ease of maintenance.

8. Sleeve type bearingProvided at each stage to assure stable operation away from critical speed.

9. Wear ringsDual wear rings for enclosed impellers and bowls, permits re-establishing initial running clearances and e�ciency at lower cost. Hard facing of wear surface available for longer life. Wear ring can be �ushed when solids are present in the pumping liquid.

10. Keyed impellerKeyed impeller for all the pumps, suitable for pumping liquid in high temperatures. Keyed impellers provide ease if maintenance and positive locking under �uctuating load and temperature conditions.

Standard Design Features Of VTP

11. Flanged column

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

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 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 motorFlexible coupling for pump and motor when pump with thrust bearing. impeller adjustment by the nut on the top shaft.

Oil Lubricated Thrust Bearing Assembling Sets

When the VTP designed driven by VSS motor, the pump, thrust will be loaded by the thrust bearing on the top of the pump or loaded by the top thrust bearing of the VSS motor. Seoca can supply two kinds of di�erent thrust bearing assembly sets as following, design for the pumps with lower and higher thrust.

Standard thrust bearing assembly set
