The VS1 type, vertical turbine pumps with single or multistage impellers, consisting of bowl assembly. Variety of models is available to operate at 50Hz and 60Hz with wet and dry pit arrangement. Theses pumps are constructed rigidly to ensure low vibration operation. Hydraulic design is being updated with our continuous R&D efforts to meet requirements of higher efficiency and lower submergence, taking care of other parameters such as, high reliability and optimum system design.

Features: (vertical turbine pump VS1)
Constructional features (vertical turbine pump VS1):
Bowl which functions as diffuser consists vanes which are cast integrally.
These are of Francis (BHR), mixed flow (BHQ, BHM, BHK), Semi-axial (BHMa) type. Enclosed or semi-open type of impeller is offered depending upon model.
Suction bell/Impeller guide piece:
Designed for smooth inflow of water with minimum losses.
The shaft is of high tensile strength steel suitable designed considering the loads.
Either cast or fabricated, it houses line shaft bearings and directs water from bowl assembly to discharge head/elbow.
Transmission bearings: Cutless bearings are of natural/synthetic rubber / Elastomeric with outer shell of brass or suitable material. Lubrication by self/external clear water. Oil lubrication with bronze bearing is also available upon request.
Mitchell Tilting pad type or antifriction type for taking hydraulics axial thrust and weight of rotor assembly. Lubrication is with oil or grease. Thrust bearing arrangement is available either independently in pump and drive or combined thrust arrangement in drive.
Discharge head/Discharge Tee:
To direct flow from column pipe to discharge pipe located above or below ground level with single floor ir two-floor arrangement as per requirement.
To prevent reverse rotation, available on request
Rigid construction to ensure vibration-free operation of pump set.
For pump and prime mover flexible or rigid as per requirement. For line shaft threaded barrel or muff type as per requirement.
Direction of rotation:
Clockwise when viewed from driving end.
Electric motor with vertical solid/ hollow shaft is a standard arrangement.
Diesel engine / steam turbine available with a right angle gear unit upon request.
High efficiency and low submergence:
The vertical turbine pump VS1 hydraulic design is being updated with our continuous R&D efforts to meet requirements of high efficiency and low submergence, taking care of other parameters, such as high reliability and optimum system design.
