The design of a Tsurumi Pump: Double Mechanical SiC Seal

  • 1 min read

Double mechanical SiC seal in oil bath

All Tsurumi products contain a double mechanical seal for increased durability.

 How? 

The isolation of the fixed upper and lower mechanical seals in the oil chamber provides a clean, non-corrosive and abrasion-free lubricating environment this prevents spring failure caused by corrosion, abrasion and bottom seal failure due to loss of cooling during dry run conditions. 

 

The double mechanical seals within all Tsurumi pumps have sealing rings made from Silicon Carbide this is chosen for the properties of the material. Silicon Carbide is known for its resistance to temperature fluctuation and corrosion combined with its durability.
