Rotor Screw Pump Technical Facts & Performance Descriptions
What are the key manufacturing tolerances required for a high-quality Rotor screw pump?
To maintain optimal volumetric efficiency and prevent internal fluid slip, our CNC machining processes ensure micron-level clearances between the helical rotor and the elastomeric stator. This precise engineering is fundamental to the reliable operation of any Variable Speed Screw Pump subjected to fluctuating discharge pressures.
How does the rotor surface treatment process extend the lifespan of a Rotor screw pump?
During manufacturing, the metallic rotors undergo specialized heat treatment and surface hardening, such as hard chrome plating or vacuum ion coating. This creates a highly wear-resistant surface that protects the core rotor pump components against severe abrasion when handling industrial slurries or particulate-laden fluids.
What factors determine the stator material selection during the production of a Rotor screw pump?
Stator material is strictly chosen based on the pumped fluid’s chemical compatibility, operating temperature, and abrasiveness. We mold stators from premium elastomers like NBR, EPDM, or FKM, ensuring chemical resistance comparable to a specialized Fluoroplastic Pump while maintaining the necessary flexibility for the progressing cavity sealing mechanism.
How does the internal cavity design of a Rotor screw pump prevent fluid degradation?
Unlike high-speed impellers, the engineered internal geometry of a Rotor screw pump forms sealed, continuous cavities that progress linearly. This generates a smooth, non-pulsating flow with ultra-low shear, making it vastly superior to a standard High Efficiency Split Case Pump for transferring fragile polymers, flocculants, or shear-sensitive emulsions.
What factory performance tests are conducted on a KOLEBURG Rotor screw pump prior to shipment?
Every unit undergoes rigorous factory acceptance testing (FAT) directly on our manufacturing line. This includes hydrostatic casing pressure tests, mechanical seal leak detection, and full-curve flow rate verification, ensuring the equipment meets strict mechanical integrity standards before it arrives at your facility.
