Tandem Double Cartridge Seal
A versatile, proven performer providing reliable double sealing capability in a wide variety of industrial processes.
A high performance, tandem arrangement used primarily in refining and chemical applications. This seal is ideal for non-lubricating fluids-light hydrocarbon services requiring low heat generation. It is designed with simplicity in mind, so seal repair is easy and economical.
This simple tandem orientation provides higher pressure capabilities in light hydrocarbon refining applications. The outboard seal face serves as a high efficiency pumping ring and provides maximum cooling capability in the most demanding services.
- Tandem configuration for high pressures
- Low heat generation monolithic seal faces
- Bidirectional barrier fluid ports to accomodate double ended pumps
