SPECIAL DUTY SEALS - DOUBLE CARTRIDGE OUS - OVER UNDER SEAL The SEPCO� OUS mounts externally and is a multiple cartridge- mounted assembly for installation where first obstruction space is limited. It can handle up to 5/32" shaft deflection making it ideal for equipment where movement is excessive. The heavy duty design allows for successful operation where stuffing box pres- sure operates higher than safely handled by off-the-shelf designs. Rotary or Stationary Design The OUS is available in both rotary and stationary designs. The rotary is preferred on equipment with excessive shaft deflection and the stationary design where high PV factors are encountered. Hydraulically Balanced This allows for changes in operating pressures without face sep- aration. Reduced hydraulic loads allow operation on high pres- sure without reducing lubrication critical for cooler operation. Cartridge Mounted A self-contained unit pre-assembled and pre-set at the factory eases installation and maintenance. When seal leakage occurs, the unique design allows the seal to be slid back and the stuffing box packed to control leakage until an outage can be scheduled. Multiple Seal Design Allows for installation where hazardous, abrasive, non-lubricating products are handled that require injection of a neutral liquid from an external source without diluting the pumped product. The seal can operate in either a double or tandem mode. Isolated Multiple Springs Multiple springs provide even mechanical loads for cooler operation and are isolated from the pumped product to elim- inate clogging from suspended solids.
