Rheodyne Rotor Seals and StatorsRheodyne Rotor Seals and Stators

Rotor Seals and StatorsThe rotor seal is the polymeric disc that makes a high pressure seal againstthe stator. The seal wears with use and is one of the only parts that may needroutine replacement. Stators need replacement only if the ports or sealingsurfaces become damaged.

Vespel blend rotor seals have an operating pH range from 0 to 10. Tefzel blendand PEEK blend rotor seals have a pH range from 0 to 14. Strong oxidizing acids such as concentrated nitric and sulfuric are not compatiblewith PEEK.

Stators are available in 316 stainless steel and PEEK. Our materials of construction have been researched and selected for their physical and mechanical strength.

The standard rotor seal in many Rheodyne manual valves is madefrom a Vespel blend. This polyimide has low wear and high chemicalresistance. Vespel tolerates a pH range of 0 to 10. Solutions morebasic than pH 10 dissolve Vespel which damages the rotor seal.Ifyou use any solutions above pH 10, Rheodyne recommends aPEEK blend rotor seal. PEEK offers a high chemical resistance andversatility, and will tolerate the entire pH range from 0 to 14. Tefzelblend rotor seals may be appropriate for some applications.Replacement rotor seals are listed on page 20.

Genuine Rheodyne rotor seals are matchless in performance andproduct life. For a quarter of a century they have exceeded theneeds and expectations of chromatographers. Our rotor seals areproducts of rigid manufacturing and quality assurance proceduresbefore they are incorporated into our valves or shipped to our customers. Only genuine Rheodyne parts ensure the continuedprecision performance of Rheodyne valves.

Our engineers develop exacting product specifications anddesigns including the factory-installed rotor seal ring which optimizes rotor seal efficiency. Rheodyne rotor seals must passour tougher-than-real-world standards of performance. Rheodynerotor seals are made from proprietary-blended polymers, formulated specifically for resistance to repetitive chemical andphysical stresses of the entire 0 to 14 pH range.

Tested under actual laboratory conditions, Rheodyne rotor sealsfully meet the demanding requirements of day-to-day manualinstrument use as well as the operating conditions found in today'sautomated laboratories.
