RCS-S Cartridge mechanical seals

Cartridge mechanical seals manufactured to meet API 682 (ISO21049) are meant for use in the petroleum, natural gas and chemical industries.

During processing of crude oil various chemical compounds are being released, and designers should count on sealing fluids which could be:

- under the very high pressure;

- under very high or very low temperatures;

- on very high or low pH value;

- very high or very low viscosity;

- abrasive;

- harmful, polluting and potentially explosive.

API 682 (ISO21049) specifies requirements and gives recommendations for sealing systems with aim to secure that the fluids with characteristics above could be transported:

- with minimum waste;

- with maximum environmental protection;

- with minimum mechanical failure;

- with best price-quality ratio.

Do not require any adaptation of the pump

When ordering the seal, it is necessary to specify the pump brand, shaft diameter, working conditions (pumped working medium, temperature) and the type of fixed connection (seats, rings)
