Stainless Steel Submersible Pump

الوصف

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.
Special Features of Pumps

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