Openwell Monoset Pumps


  • Compactly designed pump set for easy handling and installation.
  • High-grade cast iron for a better life even in heavy and contaminated water.
  • Front side carbon bearing with Stainless Steel Thrust Plate and Backside SG Iron Plate with Gunmetal Bush for longer life under various conditions.
  • Stamping is done with Electrical Grade Silicon Steel for lower power consumption and higher product life.
  • Advanced Hydraulic Design for highest energy efficiency in the pump set.
  • Dynamically Balancing Rotating part to ensure minimum noise and vibration-free operation.
  • No Foundation Required
  • Pump always Operates under water hence
    • No suction or Priming Problem.
    • No Possibility of burning of motor.
    • No water level gaurd required
    • Noise Free, Leak Proof
    • No galnd Leakage
    • No regular maintenance required in has compared to monoblock or couple
  • Motor designed to withstand wider voltage fluctuation.
  • Monoset pumps are generally installed at the bottom of tank/well , its performance do not affect due to change in water level.
  • Foot valve and elaborate suction piping are not required as pump set is fully submerged in water and hence no priming problem.


  • Irrigation from open wells, specially where there is a wide fluctuation in water levels
  • Community water supply from open wells
  • Canals and rivers
  • Agriculture
  • Pumping of water in multistroied building.
  • Open well Submersible
  • Water supply for cooling tower
