58A-Heavy Duty Stationary

The Style 58A single cartridge seal is specifically designed for ruggedness and durability to withstand high pressure applications. Design elements include a piloted gland to positively center the seal assembly, as well as a metal-to-metal confined gland gasket which prevents blowout or extrusion of the gland packing.

Features:

• Stationary design for maximum face alignment
• Robust and reliable seal face drive
• Hydraulically balanced
• Dynamic O-ring moves to a clean surface
• Springs located out of product to prevent clogging and hang-up
• Rugged construction for high pressure applications
• API compliant with piloted gland to positively center seal assembly and metal-to-metal confined gland gasket which prevents blow out or extrusion of the gland packing
• Carbon floating bushing option available
• API 682 Type A Arrangement 1 available
• Multi-point injection feature available which ensures maximum uniformity of cooling around the entire circumference of the sealing faces, thus eliminating face distortion due to uneven cooling. Ideal for boiler feed and light flashing hydrocarbon services.
• Thicker cartridge sleeve construction to eliminate distortion due to tightening of set screws
• Gland NPT connections: 1/2″ NPT for process side and 3/8″ NPT for atmospheric side to help prevent improper installation
