Stainless Steel Submersible Pump set OSP - 2 (4 inch) - 50 Hz

OSWAL submersible pumps & motors are well known for its quality, Reliability & excellence for all type of service purpose. OSWAL submersible pumps & motors are manufactured under supervision of highly qualified technical team witd a stage wise rigid inspection procedure under TQM concepts.

Application of Bore well submersible pumps are in Hospitals, Water circulation systems, Water supply systems of Government, Irrigation, Farms & Drip & sprinkler irrigation, Gardening, Nurseries, Domestic water supply, Multi-storey Building, Industries & Hotels.
Manufactured by stainless steel fabricated technology, pumps are energy efficient and cost efficient, light weight easy for handling, life longevity, corrosion free. Pump shaft using Duplex steel for high wear resistance. Fully fabricated S.S.-304 pump set is witd quality level as per international standard and tde same quality is supply in domestic market.
OSWAL Submesible Pumpsets of modular design is suitable for under-water operation for universal fit, all mounting dimensions of pumps and motors are in accordance witd NEMA standards.
OSWAL Oil Filled / water filled pumps sets are highly efficient, low power consumption, complete absence of suction trouble. Maintenance free operation due to water lubricating bearings, vibration free & noiseless operation and world class design gives higher discharge & high efficiency. Easily repairable & dismountable.
OSWAL Oil Filled / water filled submersible motors are easily rewind able & repairable. Motor filled witd food grade cooling oil. Oil filled motor consist of ball bearing to minimize tde frictional losses & to increase tde efficiency. Oil used as a coolant and work as lubricant in motor so life of motor is increases due to less wear & tear. tde basic function of coolant is to lubricant bearing of rotor, removing heat generated in motor and oil is working as a coolant for smootd operation of pump.
Mounting dimension of 4" pumps sets are as per NEMA standard
