The rotor of Netzsch NM021BY02S12B screw pump is a key component. It promotes the flow of liquid efficiently, ensures smooth delivery under low pulsation and low shear stress conditions, and provides reliable driving force and efficiency for fluid delivery.

Netzsch NM021BY02S12B Rotor

Material

The rotor is made of high-quality stainless steel. Stainless steel has excellent mechanical strength, corrosion resistance and wear resistance, which can ensure that the rotor maintains excellent performance and reliability in long-term use.

Surface accuracy

The surface of the rotor is precisely machined to achieve a very high finish. This can minimize the friction and leakage between the rotor and the stator, and improve the efficiency and sealing of the pump.

Matching with the stator

The rotor is spiral-shaped and forms a closed pump cavity by matching with the stator to achieve fluid delivery. The rotor and the stator maintain a very small gap match. This precise match ensures a good seal between the rotor and the stator, avoiding unnecessary leakage and energy loss.

People also ask

A screw pump is a type of rotary pump which is equipped with screws that mesh together and rotate within a cylindrical cavity or liner. The fluid enters from the suction side of the pump and moves linearly along with these intermeshing screws to the discharge side of the pump.

Screw pumps are more helpful in pumping heavy oil. They even have the ability to pump higher flow rates and higher viscosity fluids. These pumps are capable of pumping both liquids and gases. For this reason, these pumps are used in many pumping industries.
