product

DBM SIMCO 320 is a three piece double acting compact seal which consists of one fabric reinforced elastomeric sealing element and two thermoplastic guide back-up rings

PRODUCT ADVANTAGES

  • Low friction , free of stick-slip
  • Improved abrasion resistance
  • Good dynamic and static sealing
  • Long service life

APPLICATION
Mining equipment , iron and steel industry , marine hydraulics and earth moving equipment.

INSTALLATION

DBM SIMKO 320 profile is designed for installation in open or closed grooves. We recommend the open groove design for pistons that are smaller than Ø 50 mm. It is important that the assembly tool has to be soft material, and no sharp edges. For the installation of the seal element needs to be lubricated with oil system.
