The LORENTZ (HR) helical rotor pumps are designed to be both efficient and robust. The HR helical rotor pumps are a positive displacement pump, the rotor has an eccentric movement which when rotating inside the stator effectively squeezes water through the pump on every rotation.

Helical rotor submersible pumps are ideal for handling high-viscosity fluids, liquids containing solid particles, and abrasive materials. They are commonly used in wastewater treatment, oil extraction, and agricultural irrigation.

The helical rotor pump is a class of positive displacement pump that works by the rotation of a helical rotor pushing discrete quantities of liquids through the pump. A corkscrew-like action provides a pulse free flow where an accurate flow rate is determined by the rotor speed allowing for the helical rotor pump to also be used as a dosing pump.

Roto Helical rotor pumps are used in more than 25 industries such as paint, paper, chemical, marine, navy, biogas, oil & gas, waste water etc. for transfer of liquids with different properties like viscosity, shear sensitiveness, abrasiveness, corrosive etc.

Helical Rotor Pumps are a sturdy and robust category of Positive Displacement Pumps. These pumps comprise of a helix rubber stator and a helical rotor. The rotor is fitted inside the stator which is lined with rubber. The rotor rotating inside the stator forms cavities via which media is pumped from suction to the discharge end of the pump.

The progressing cavity working principle in particular consists of a spiralled helical rotor (like a cork screw, hence their names eccentric screw pump) that sits tightly inside a rubber stator/sleeve.

Helical Rotor Pumps are non-shearing pumps, and can transfer a variety of liquids without causing any change or harm to their quality. Moreover, these pumps are considered to cab be used for semi hygienic food and beverages applications such …

HR DC pumps (Helical Rotor) have been developed to meet the low cost pumping system needs without sacrificing quality, reliability or performance. The positive displacement Helical Rotor (HR) AC-DC pumps can be powered by AC or DC power ranging from 120-400 VDC or 120-265 VAC.
