Mechanical seals • Mechanical seals for pumps

No matter seal rings made of high-performance carbon graphite material, slide bearings made of unique SiC-C composite material or components for dry-running pumps - our customized materials impress with low friction, low wear and high chemical and thermal shock resistance.

We mainly provide universal mechanical accessories, dynamic and static rings, springs, and complete sets of components. The product is commonly used for sealing various pumps. In terms of material selection, we provide customized product services based on the actual product usage environment and the special usage requirements of customers.

1. About our products :

  1) Because of using wafer spring, the force acting on the sealing surface is more uniform , the tracking ability performance 

     of water seal is improved significantly

  2) Lower working height. It can improve seal’s working surroundings.

  3) Adhesive structure

2.  About material Chosen Principals:

  Antifreeze Type:  Organic acids series, phosphoric acids series, half-organic acids series.

  Speed:  Max 6000rpm 

  Mating ring code : M

  Silica series : Mating ring code V

  Rubber : NBR

3. Water seals assembly:

  1) To use the following tools (fixture)while fitting water seal by pressure. In addition, axial runout of the retainer’s big end face must be 

within 0.15mm while taking the shaft of bearing as benchmark.

  2) The working height of water seal must be within ±0.1mm around the basic working height .

4.  Seal operating :

   Dry run (dry friction)should be avoided after mounting water seal as possible. This means water seal must be operate in the filled sealing liquid.  If dry run is necessary when testing leakage of water seal, speed should be within 200 rpm.

Advantages:

With the high quality against friction and wear

Self-lubricating, extremely stable, and resistant to heat and corrosion

 Low friction, and extremely reduced wear
