Rotor Seals and Stators
The rotor seal is the polymeric disc that makes a high pressure seal against the stator or stator face seal. The seal wears with use and is one of the only parts that may need routine replacement. Stators are available in 316 stainless steel, PEEK™ and proprietary materials. Stators need replacement only if the ports or sealing surfaces become damaged. Avoid damage from use of improper injection needles by referring to the “Using Proper Syringe Needles” Application Note.
Please Note: Rotor seals for MX Series II™ Modules are available in RheBuild Kits. Stators for MX Series II Modules are available, MX (Series I) Module rotor seals are available in RheBuild Kits and stators are available at www.idex-hs.com.
Application NOTE:
How to Select the Right Rotor Seal -
The standard rotor seal in many RheodyneR manual valves is made from a VespelR blend. This polyimide has low wear and high chemical resistance. Vespel tolerates a pH range of 0 to 10. Solutions more basic than pH 10 dissolve Vespel which damages the rotor seal. If you use any solutions above pH 10, Rheodyne recommends a PEEK blend rotor seal. PEEK offers a high chemical resistance and versatility, and will tolerate the entire pH range from 0 to 14. ETFE blend rotor seals are appropriate for use in applications where PEEK is not generally acceptable, such as when methylene chloride or DMSO in higher concentrations is being used.
