Stainless Steel Submersible Pumps


Stainless Steel Submersible Pumps

Naigra Sheet Metal Stainless Steel Submersible pump are specially designed, with the use of latest manufacturing techniques. Years of experience, superior design and better manufacturing techniques have resulted into development of this range of pumps, which are efficient and reliable in operation. Strict quality assurance standards during the total process assure trouble free and reliability in operation requiring minimum maintenance. The pump range consist of many pump sizes is available with an optional number of stages to match any duty point.

  •     Starting Per hour : Max 15 to 20
  •     Normal Outlet Size : 2”, 2.5” , 3” & 4”
  •     Immersion : 1 Mtr minimum
  •     Pumped liquid : Clean Free from solid chemically natural and close to the characteristics of wate

  • Low weight high efficiency
  • Suitable to 4” , 6 “ & 8” Submersible Motor.
  • All bearings are water- lubricated and have a square shape, enabling sand particles, if any, to leave the pump together with the pumped liquid.
  • Bearing bush is made of anti friction rubber to withstand wear resistance.
  • Non return Valve made in stainless steel (AISI 304 Grade). The valve casing is designed for optimum hydraulic properties to minimize the pressure loss across the valve and, thus, contributes to the high efficiency of the pump.
  • Pump motor coupling is according to NEMA standard.
  • Redial flow and mixed flow impellers & bowl made from stainless steel (AISI 304 Grade).
  • Stop Ring which is designed as thrust bearings limits axial movements of pump shaft.
  • Suction Case , stage casing and discharge chambers are made by stainless steel (AISI 304 Grade)from sheet metal so rust free and long service life
  • The inlet strainer prevents particles over a certain size from entering the pump.
