main feature:

Cartridge series mechanical seal structure;

The primary seal bears all the pressure of the process, and the secondary seal is low pressure or normal pressure;

The primary sealing end face is provided with an upstream pumping spiral groove, and the secondary sealing liquid is transported to the upstream process medium during work. Avoid leakage of process media;

Liquid film lubrication, low power consumption;

Adapted to granular media.

Using parameters:

Pressure: 0 ~ 2.5MPaG

Temperature: -40 ~ 200 ℃

Speed: ≤20m / s
