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.
