Mechanical seals

Mechanical seal is the type of seal to use in rotating equipment to guarantee sealing of the shaft that transmits mechanical energy to movable operating element of pumps, compressors, chemical reactors, vacuum filters-drying machines, mixing machines etc., i.e. where two operating environments need to be separated to guarantee minimal efflux. Such devices are applied in hydrocarbon process industry, food and pharmaceutical industries. Specifically pumps and mixing machines are used in production of alcoholic and nonalcoholic beverages, mineral water, oil, milk products, food supplements, food additives, pharmaceuticals etc.

Friction pair is the crucial component of the mechanical seal. Its material must have high wear-resistance and low frictional coefficient. According to its construction mechanical seals can be inner and outer, single and double.

The type of the seal’s construction largely depends on physicochemical properties of the environment for which the seal was designated: its state of aggregation (gas, liquid), pressure, temperature, viscosity, suspended solids and salts content, chemical aggressivity, flammability (while heating, in contact with atmospheric environment), potential health effects and environmental hazards.

The AvtokomTehnology group of companies is the official dealer of Kroma Ltd (Serbia), european mechanical seals manufacturer. We are ready to offer fine quality at a reasonable price.

Our specialists will select matching mechanical seals for pumps Grundfos, KSB, Hilge, Alfa Laval, APV, Wilo, Fristam, Ebara etc, and analogs of mechanical seals AESSEAL, Burgmann, John Crane, Roten, Vulcan.

Various types of mechanical seals are represented in our catalogue, it allows to select best possible option for any production problems solution.
