Screw Pumps Dealers in Salem

The unique pumping principle applied, employs a highly precision manufactured Metalic single helical rotor turning inside a double internal helical resilent stator. Thereby forming cavities confined by a "Sealing Line" which is maintained at stand still and during rotation. Whilst the rotor rotates in the stator, the cavity formed between them progresses from suction to delivery side, gently carrying the medium.        Good self priming properties even with air or gas inclusion in the liquid upto 8.5 MWC.        Handles solids in suspension or mixture containing high percentage of solids. Bigger size pumps upto 40mm dia.        Steady and smooth flow with little pulsation makes it suitable for dosing and metering duties.        Direction of the flow through the pump is reversible by merely changing direction of rotation of the prime mover.        The pressure head is independent of speed and capacity is propotional to speed.        Gate and check valves are not necessary.        The metal bonded high precision moulded stator ensures high efficiency pressure and increases life.
