Mechanical seal R-802
Mechanical seal R-802
Double mechanical seal R-802 is a combination of two seals, with the location of friction couples surfaces on opposite sides. R-802 is multi-spring, unbalanced, with sealing o-rings. To cool the seal surface during the operation, the barrier fluid circulates in the seal chamber at a higher pressure (for one bar) than the pumped fluid.
Appliance: food industry, petrochemical industry, water supply and wastewater treatment, and other areas where the pumped liquid is toxic, viscous and contains abrasives and solids.
Temperature: -20~180 °C
Pressure: ≤0.5 MPa
Speed: ≤12 m/sec
Materials:
- Rotary ring: SIC/TC;
- Stationary ring: Carbon/SIC/TC;
- Bellows: NBR/EPDM/VITON;
- Spring: SS304/SS316;
- Metal parts: SS304/SS316.
