Rigid vertical rotor cum pump shaft dynamically balanced, held between a single row ball bearing at non driving end and double row angular contact ball bearing at driving end which take care of axial and radial forces acting on pump. Impellers are also dynamically balanced. The distance between the bearings and impeller is kept as short as possible, virtually eliminating shaft deflection. This results in low vibration, practically silent operation, as well as longer bearing and seal life of the Sewage Submersible Pump.

APPLICATIONS OF SUBMERSIBLE PUMPS :Tube well irrigation, Industrial & Public Water Supply Schemes, Domestic water supply, Lift Irrigation Schemes, Drip / Sprinkler Irrigation Schemes, Fire fighting, Booster application, Cooling water circulation, Ornamental fountain installations and air conditioning plants. Dewatering of mines, Offshore platforms, etc. CONSTRUCTION OF SUBMERSIBLE PUMPS :Single or multistage, radial or mixed flow impeller pump with NEMA coupling, wet squirrel cage induction type, water cooled, water lubricated motor. All bearings are water lubricated

Stator is wound with ' F ' class insulation wire which is rated upto 155 ºC. Stator and windings are vacuum impregnated to ensure 15 starts per hour. Motors are driven with three phase 415 volts, 50 HZ power supply. Motor incorporates water proof / oil proof EPR insulated double sheated copper conductors flexible cable. HYDRAULICS Specially designed high efficiency volute casing & impeller, Hydrodynamically balanced, smooth flow pattern less risk of clogging with self cleaning abilities, Cutter type impeller suitable for handling high viscous sewage, fibre. DYNAMICSRigid vertical rotor cum pump shaft dynamically balanced, held between a single row ball bearing at non driving end and double row angular contact ball bearing at driving end which take care of axial and radial forces acting on pump. Impellers are also dynamically balanced. The distance between the bearings and impeller is kept as short as possible, virtually eliminating shaft deflection. This results in low vibration, practically silent operation, as well as longer bearing and seal life of the Sewage Submersible Pump. SEALING1) Compact twin seals ( in board TC -TC & outboard  TC - TC ) operating in tandem ensures perfect sealing.2) Cable sealed with special additive to prevent ingress of liquid in the Sewage Submersible Pump set. PROTECTION DEVICES ( OPTIONAL )1 ) Automatic On / Off / On thermal Switches to prevent over heating of motor.2) Moisture sensor that detects progressive seal wear.3) Pump equipped with zinc anodes to prevent corrosion4) Liquid level indicator to prevent dry running of pump. COOLING SYSTEM1) Integrally cast fins on motor body with large surface area provide for good heat dissipation & cooling of Motor.2) In addition to lubrication of bearings, the oil in oil chamber carries away heat from bearings. 

Polder pumpsets are single two stage centrifugal pump with impellers of mixed flow design. The water to be lifted flows through a passage tube and is pumped around the motor and up into the discharge main. The motor is a wet type water filled submersible motor, robust in design and light in weight. Motor cooling is done by delivery liquid ensuring long life by the jacketted construction. Mechanical seal is provided to prevent entry of muddy and sandy water into the motor. Axial thrust is controlled by adequate thrust bearing. Calama Polder pump offers a wide range of models for lifting water from 6-90 mts. and a discharge of 800 to 18000 LPM. These pumps can take turbidity upto 10000 ppm and handle Maximum particale size upto 8 mm.
