The design of the mechanical seal consists mainly of two parts: a movable part and a fixed part. The fixed part is usually a ring that is fixed in the pump housing. The movable part is mounted on the shaft and is pressed against the fixed part by means of a spring.

Mechanical sealing is achieved using secondary seals (bellows, rubber rings) and a friction pair.

Mechanical shaft seals for Grundfos pumps

Supply of analogues of mechanical seals for GRUNDFOS pumps.

In GRUNDFOS pumps (grundfos), bellows seals are mainly installed. In order to buy a mechanical seal for GRUNDFOS, you need to know the type designation "MG12/28-Z G60" or the pump part number. We select seals according to the sample, according to the GRUNDFOS pump article or according to the markings of Burgmann, John Crane, Roten, AESSEAL and other seal manufacturers.

A mechanical seal is used, which consists of: a movable and a fixed part. The fixed part is the ring (seat), which is fixed in the pump casing. The movable part is attached to the shaft and is clamped by means of a spring to the fixed part. Mechanical sealing is achieved using secondary mechanical seals (bellows, rubber rings) and a friction pair. When choosing a mechanical seal, it is important to choose the material of the secondary seals and friction pairs.
