Sale, selection, development, production of mechanical seals for pumps

Mechanical end seals is an effective sealing device used in rotating equipment such as pumps, agitators and mixers.

Due to their use, the loss of the pumped liquid through the end seal.

In mechanical seals, tightness is achieved due to the tight compression of two parts along the end planes - a rotating and a stationary one.

The main node is a pair of friction. The following materials are mainly used: silicon carbide-ceramic, silicon carbide-silicon carbide. Other high-quality materials are also used.

Benefits:

Reliable sealing of the shaft;
reducing operating costs;
exclusion of additional finishing of sealing parts during installation;
the ability to work in various environments, including aggressive and abrasive;
interchangeable with most domestic seals.

Our experts will help you choose a high-quality cost-effective replacement for mechanical seals of well-known manufacturers Burgmann, John Crane, Roten, AESSEAL, Anga, Vulcan and more.
