Standard Screw Pumps

Standard Screw Pumps

Heavy-duty RD/RM series pumps are designed for continuous duty or intermittent duty, suitable for efficient handling of demanding tasks in the wastewater treatment, wastewater treatment, liquid transfer industries in chemical and food industries. The pumps are available in monoblock or bare shaft designs.

High-performance, cost-effective pumps of RL series use an extended rotor/stator working pair geometry and are ideal for use in sewage treatment plants. The pumps are available in monoblock or bare shaft designs.

Heavy duty compact RE pumps are designed for high pressures thanks to the use of stators of equal wall thickness (flat profile stators) that are capable of generating 12 bar per cycle.

Operation principle of screw pumps

The pumping element consists of a precision machined single outer spiral metal rotor and a double inner spiral elastomeric stator. Due to a special shape of the rotor and stator, a sealed line is formed along the rotor axis, which is maintained both in a static and dynamic state.

As the rotor rotates inside the stator, these cavities move from the suction port to the pump outlet port.
