Mechanical seals in hostile environment
AvtokomTehnolodgy supplies food industry companies with mechanical seals for pumps produced by Hilge, KSB, Grundfos, Packo, Ebara, Wilo, Tuchenhagen, Alfa Laval, APV, Fristam and others.
Our specialists select mechanical seals for any pump operating condition, including hostile environment. The most suitable material for operation in such environment is Kalrez®. This material is characterized by unique resistance to chemical impacts. It is not soluble and does not swell in practically all solvents (alcohol, simple ethers and esters, aromatic amines, phosphorous ethers, etc.). In fact, Kalrez® is not resistant only to some freons and aliphatic amines, for example, hexamethylene-diamine. Kalrez® is used in products which require extremely high chemical resistance, but it is not widely used due to its high cost. If you are experiencing problems with your pumps operating in hostile environment, we can help you.

When you buy mechanical seals with Kalrez® material from us, you get:
- stable operation of equipment;
- elimination of emergency stops;
- reduced product losses;
- reduced equipment repair costs.
