Rotor and Stator Set for Progressing Cavity Pumps
Original price was: $ 160,00.$ 150,00Current price is: $ 150,00.
High-performance Rotor and Stator replacement kit designed for progressing cavity pumps. Engineered for durability and precision, this set ensures efficient fluid transfer and consistent pressure for industrial and construction applications.
Description
This professional-grade Rotor and Stator assembly is the heart of a progressing cavity (PC) pump system, specifically designed to handle viscous, abrasive, or shear-sensitive materials.
The Rotor (black) is precision-machined from high-strength wear-resistant steel, featuring a smooth, helical profile to minimize friction. The Stator (red) is molded with a high-quality elastomer sleeve, providing the necessary interference fit to create sealed cavities that move material forward as the rotor turns.
This combination is ideal for plastering machines, grout pumps, and industrial wastewater applications. Its robust design ensures a long service life, reduced maintenance downtime, and steady flow rates even under high-pressure conditions.
Key Features:
-
Precision Engineering: Optimized geometry for maximum volumetric efficiency.
-
Durable Materials: High-grade steel rotor and abrasion-resistant elastomer stator.
-
Versatile Application: Compatible with a wide range of mortar, screed, and industrial sludges.
-
Easy Installation: Standardized fitting for quick replacement in existing pump housings.
