Mech seal components seals-M74-D

M 74 D mechanical seal is a kind of high-quality mechanical seal with good performance and reliable quality, which is designed and produced according to the latest technology and experience. It is widely used in various industrial pumps, valves and other rotating shaft sealing occasions.

The main working principle of M 74 D mechanical seal is to form a sealed face between the fixed seat and the rotating ring, and ensure that there is no leakage of the sealed medium by using the elasticity of the sealing face material and the dynamic sealing action of the spring.

The main features of M 74 D mechanical seal are: small size, light weight, low starting torque, good sealing performance, long service life, etc. It can effectively seal various corrosive, viscous, volatile and solid-liquid mixed media. It is an ideal choice for sealing in harsh conditions.

M 74 D mechanical seal has a wide range of specifications and varieties, which can meet the different needs of different working conditions and pump sizes. The standard size range is from 10mm to 200mm. It can also be customized according to customer needs.
