Rodelta BHA (VS3) Axial vertical turbine

The BHA is a VS3 type, vertical turbine pump with axial single stage impeller, consisting of diffuser (stator) 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.

Constructional features:

The stator which functions as diffuser consists vanes which are casted integrally.

These are of Axial 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.

Column pipe:
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.

–  Thrust bearing:
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.

Non-reverse ratchet:
To prevent reverse rotation, available on request

Motor stool:
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 VS3 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.
