Screw Pumps

The AM / BM - Series Positive Displacement Progressive Cavity Screw Pumps has unique pumping principle applied employs a highly precision manufactured Metallic Single helical rotor turning inside a double internal helical resilient stator. Thereby forming cavities confined by a “Sealing Line” which is maintained at stand still and during rotation. While the rotor rotates in the stator, the cavity formed between them progresses form suction to delivery side, gently carrying the medium.

• Good self priming properties even with air or gas inclusion in the liquid up to 8.5 MWC.
• Handles solids in suspension or mixture containing high percentage of solids. Bigger size pumps up to 40 mm 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 proportional to speed.
• Gate and check valves are not necessary.
• The metal bonded high precision molded stator ensures, high efficiency pressure and increased life.

It is suitable for dosing and metering duties because of its sturdy and smooth flow with slight pulsation. Stator is metal bonded, guarantees high efficiency, pressure and improved life.
