Slim Cartridge Double Seal 'MD291'

Stafin box exterior structure, thin double seal with direct injection cooling method.

This is a double-type ultra-thin cartridge seal. It can be easily installed without modification on the stuffing box of the pump you are currently using, as well as on pumps with particularly narrow atmospheric side spaces. 【Features】 - Flexible mounting capability. - No need for additional processing of the stuffing box of the pump in use, making installation easy. - No wear on the shaft or sleeve. - Since the spring and knock pin do not come into contact with the fluid, it can avoid operational failures or sticking caused by slurry. - Being stationary, it achieves excellent followability. - The flushing and circulation are directly injected into the sliding surface using a direct injection cooling method, effectively cooling the sliding surface. - The intermediate part of the double seal can be used in both pressurized and non-pressurized states. - In the intermediate pressurized state, there is no leakage of pump fluid to the outside. - In the intermediate non-pressurized state, there is no leakage of intermediate fluid into the inside. - The atmospheric side seal acts as a backup seal, allowing the pump to continue operating even in the event of an abnormality on the inside.
