Brand reference:78558

C. Otto Gehrckens GmbH & Co. KG (COG) was founded in 1867, and 1919 acquired the leather processing company C. Otto Gehrckens, and continued operations under this name. Starting in 1955, it transitioned from leather processing to rubber processing, producing V-belts and elastomeric seals since then. COG has the world's largest inventory of O-ring bearings, with tooling for approximately 22000 different sizes of O rings.

German COG seals, COG models, COG prices
COG seals refer to devices that prevent fluid leakage, formed by at least one pair of end faces perpendicular to the axis of rotation. These faces remain in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, along with the assistance of auxiliary seals. When the auxiliary seal of the compensation ring is a metal bellows, it is called a bellows mechanical seal. There are mainly the following four types of components: a. Primary sealing elements: rotating ring and stationary ring. b. Auxiliary sealing elements: O-rings. c. Clamping elements: springs, thrust rings. d. Drive elements: spring seats and keys or fixing screws. The function of COG seals is to prevent high-pressure liquid

COG seals are a type of friction seal or stuffing box used to prevent liquid leakage between the shaft and bearing of compressors or other fluid handling equipment. They are also sealing devices designed to prevent leakage at the pump shaft and housing. Common types of shaft seals include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is typically a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals for rotary pumps (including vane pumps, rotor pumps, etc.) mainly consist of packing seals, mechanical seals, and dynamic seals. Features of COG seals: 1) No need to measure the seal working length during installation;
