Type 207A(API 610) is a single seal for most of the uses in the refinery and petrochemical to 220 ?C. It is complete with throttle bush, circulation and quench. The mechanical seal combines the essential elements API for operation with universal deployment options. It is particularly suitable for the standardization, which results in the reduction of maintenance and production shortfalls in minimized.

Features:

• simple
• pre-assembled
• pressured lightweight
• both directions of rotation
• more springs (protected)
• stabile construction

Limit data:

Type 851T (API 610) is a safety tandem mechanical seal specially for sealing easy and selfigniting media, for example. light hydrocarbons, LPG / liquid gases, solvents and etc., and also in conjunction with the two-phase connection and deployment at low temperatures. Due to the special geometry of the surface of the slide ring, use only massive sliding counter-ring, as well as due to the small contact area under thermal stress is achieved by extending the useful life of mechanical seals and increase safety. Mechanical seal fulfills T?V prescription TRB 1801 of liquid gas.

Features:

• double
• pre-assembled
• pressured lightweight
• both directions of rotation
• more springs

Limit data:

Type 875A(API 682) is a mechanical seal for hot pumps (refinery) for example. for sealing a hot oil, hot crack of the products with the catalyst in the FCC equipment etc.It is added by optimize circulation pipe for better cooling of the sliding surfaces.

Other types of seals according to API 610/682 are:

• Type 700SA
• Type 870
• Type 875
• Type 875T
• Types 881D
• Types 881D-A

Features:

• double
• pre-assembled
• pressured lightweight
• both directions of rotation
• metal bellows
