GW GU O-Ring Pusher Cartridge Seal 4610
The GW GU is a robust, general-duty cartridge mechanical seal engineered as a direct replacement for the John Crane® Type 4610 series. Its reliable O-ring pusher construction and unitized format provide a straightforward and effective sealing solution for a wide array of rotating equipment applications.
Product Detail
+
The GW GU cartridge seal employs a proven O-ring pusher design, where elastomeric O-rings provide the primary sealing force and drive mechanism. This compact, single-cartridge configuration is engineered for reliability in general service across industries. It is particularly suited for common rotating shaft equipment such as standard ANSI and DIN process pumps, as well as various mixers and agitators.
As a fully assembled and preset unit, it eliminates complex on-site setting procedures, ensuring correct installation and immediate operational readiness. The design prioritizes ease of maintenance and interchangeability, offering a cost-effective, high-performance alternative to the OEM John Crane 4610 seal without compromising on reliability or sealing integrity. All units are manufactured under an ISO 9001 certified quality management system.
*Installation Note: Verify equipment model and seal cavity dimensions prior to installation. Ensure the shaft and seal chamber are clean and free of damage.
