HELIC’s pumping principle is unique, it 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 standstill and during rotation. Whilst the rotor rotates in the stator, the cavity formed between them progress from suction to delivery side, gently carrying the medium.

Characteristics & Features

• Good self priming properties even with air or gas inclusion in the liquid upto 8.5 MWC.
• Handles any liquid from water to solids in suspension or mixture containing high percentage of solids, compressible solids upto 40mm size, viscous and non-newtonian pastes.
• Steady and smooth flow through with a 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.
• The metal bonded high precision moulded stator ensures, high efficiency, pressure and increased life.
