R-7K / R-7K-U is a compact mechanical seal with a wave spring, suitable for any direction of shaft rotation. Can be mounted both outside and inside the medium. Ideal for operation in viscous and sticky (prone to crystallization) liquids, with high or pulsating back pressure. Often used in food and chemical pumps (in particular Mengin, Omac rotary vane pumps). Available size range for shaft diameter: d = 20 ... 100 mm. Operates at temperatures from -35 to +180°C. Pressure: ≤ 1.2 MPa, speed: ≤15 m/sec. Fixed ring options: type CC (with shortened length) and CL (with extended tail and pin slot). Type: ROTEN 7K-7KH, UNITEN 7K- 7KH, Lidering LWS71, Vulcan 1688L, AESSEAL N-W02 (AES® N-W02).
