Motor Division - Vertical Submersible Pumps

Salient Features

• High grade engineering plastic components are used, which resists corrosion and abstraction. The smooth finish of these plastic components results in high operating efficiency.
• Light Weight and hence easy to transport and install.
• Motor and pump body of stainless steel to resist corrosion and for longer life.
• Higher discharge and operating efficiency as compared to jet pumps.
• All rotating parts of motor and pump are dynamically balanced to ensure noiseless, vibration free operation and long bearing life.
• Pumps available for three phase and single phase.

Pumps Features

• Diffuser with free flow vanes reduces friction and minimises resistance to water passage and thus increases the efficiency of the pump.
• Floating impeller provides larger thrust bearing life by reducing down thrust on motor bearing.
  The Noryl material of the diffuser and impeller resists abrasive well conditions. All these factors add more years to the life of the pump.
• Non return valve is used to protect the pump components from downward hydraulic thrust during switch off.
• Sand stinger prevents sand from entering the suction sleeve and thus minimises wearout even in sandy well conditions.
• Stainless steel shaft is roll formed for increased strength and uniform load distribution.
• The tough polished stainless steel pump shell resists corrosion and serves as permanent housing for the noryl pump staging.

Motor Features (Water filled)

• Fully rewindable stator with special P.V.C. insulated winding wire with overhang and for better heat dissipation.
• The use of unique stress free shaft minimises rotor deflection, resulting in longer life. Copper rotor offers high electrical conducting for smoother & more efficient operation.
• The thrust bearing assembly absorbs axial thrust under all adverse conditions.
• Bearing bushes are made from lead bronze grade LTB - 2 as per IS 319

Motor Features (Oil filled)

• Motor are simple in construction and maintainance in case of rewinding.
• High efficiency, comparatively low power consumption.
• Can run at extremely low voltages.
• Chances of burning of motor is less as thermal overload protector is provided.
• Ball bearings are used due to which mechanical losses are negligible.
