Application Pumps for : 
 
Irrigation Urban and rural water supply Cooling Tower Fire fighting Flood control Mine dewatering Thermal power stations Condensate extraction General & Process water in industries Oil field water services and host of other needs.
Special Design Features:
Heavy wall cast iron bowls & cast iron / bronze impellers provided for maximum operating life, under arduous conditions. Impeller shafts of stainless steel. Column pipes and line shafts are machined and threaded on double ended special purpose machines in single setting ensuring concentricity. All shaft couplings in water lubricated pumps are made of stainless steel for extra long life.

Construction Features
'JYOTI' VT pumps are offered in Non-pull out construction as a standard design. The pump can be supplied for coupling with Vertical hollow shaft motors or vertical solid shaft motors. Also for surface discharge or underground discharge.

Bowls / Diffusers
Standard bowls are made of close grained cast iron. The diffuser vanes are cast integrally.

Impellers 
Impellers are closed or semi open type, statically and dynamically balanced for vibration-free operation. They are secured to the impeller shaft with tapered lock collets or keys and split rings. The impeller position can be adjusted vertically by means of impeller-adjusting nut provided in the drive.

Impeller Shaft 
Impeller shaft is of stainless steel, accurately ground to close tolerances. The shaft is supported by bearings above and below each impeller.

Column Pipes 
Column pipes are normally supplied in nominal lengths of 3.0 m, 1.5 m, and 0.75 m. Pipes of non-standard lengths also can be supplied on request.

Line Shaft
Line shafts are of high grade carbon steel, ground to close tolerances and threaded concentrically at the ends. Available in nominal lengths of 3.0 m, 1.5 m, 0.75 m and in non-standard lengths to suit specific site conditions. Line shaft in stainless steel and suitable for muff couplings also can be supplied if required.

Line Shaft Bearings
Made of bronze for oil lubricated pumps and Nitrile Rubber for water-lubricated pumps.

Shaft Enclosing Tubes (for oil-lubricated pump) 
These heavy duty steel tubes protect the line shafts from corrosion and foreign materials and support the line shaft bearings. The tubes are threaded concentrically in one setting at both ends. Available in different lengths, as line shafts.

Discharge Head 
Standard construction in cast iron. Fabricated ones also can be supplied on request.

Pump can be supplied with surface or underground discharge to suit specific site conditions.

Drives 
Electrical motors with vertical hollow shaft or vertical solid shaft are normally used. Alternatively right angle gear head with diesel engine also can be used.
