HANGZHOU, China - s4story -- Hangzhou SEALCON Fluid Machinery Co., Ltd. provides reliable mechanical seal solutions for pump manufacturers, maintenance service providers, distributors and industrial users. With increasing demand for leakage control, equipment reliability and replacement, SEALCON focuses on mechanical seal selection, pump seal replacement and OEM customization for rotating equipment.

Mechanical seal is designed to control leakage between a rotating shaft and the equipment housing. It consists of sealing faces, auxiliary seals and spring elements. Under fluid pressure and spring force, the sealing faces remain in contact and slide relative to each other, helping prevent leakage during equipment operation. It is commonly used in rotating fluid machinery such as pumps, compressors, mixers and agitators.

Mechanical Seal Types for Pump Applications

SEALCON supplies a wide range of mechanical seals, including rubber bellows mechanical seals, metal bellows mechanical seals, O-ring mechanical seals, PTFE bellows mechanical seals, PTFE wedge ring mechanical seals, cartridge mechanical seals and OEM custom mechanical seals.

Replacement Selection and OEM Custom Mechanical Seals

One of SEALCON's advantages is replacement selection for mechanical seals. Customers can provide operating parameters such as medium, working pressure, working temperature, equipment speed, pump model, drawing or nameplate. Based on these details, SEALCON can recommend suitable mechanical seal types for reference.

SEALCON mechanical seals can support replacement selection for conventional models of many domestic and international brands, including John Crane, Burgmann, AES, Roten, Depac, Flowserve, Chesterton and Vulcan. The company also provides OEM mechanical seals for different water pump brands and industrial equipment, including FLYGT, SULZER, GRUNDFOS, ALFA LAVAL, FRISTAM, GORMAN, LOWARA, IMO and others.

For many water pump applications, customers only need to provide the pump nameplate, and SEALCON can help identify the required mechanical seal type. With product variety, replacement experience and OEM customization capability, SEALCON continues to support global customers with practical mechanical seal solutions.
