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.
