Double cartridge seals
Are complete seal units
containing a gland, flush ports, sleeve, seal faces, o-rings, set screws, and gaskets.
Double seals provide an extra safety factor for those problem applications.
Nothing is simpler to install or more reliable than a cartridge seal. The 590 has multiple features that make it an exceptional, durable, long lasting, USA made seal.
Reciprocal Design- The mechanism controlling closing force to the Model 590's inboard seal face is completely automatic and regulated by the differential of pressure between the process and barrier fluid.
Cartridge Mounted- Factory assembled and pressure tested, the Model 590's cartridge unit simplifies installation and allows impeller clearance adjustments to be made without disassembling the pump.
Metal Encased Seal Faces- Both inboard and outboard seal faces are encased, protecting both plant personnel and the environment from seal face failure.
Stationary Design- The Model 590 derives sealing face alignment from the pump shaft, not the stuffing box face, creating perfect sealing face squareness automatically upon installation.
