442/442HP

Eliminates the need for equipment disassembly

The 442 Split Mechanical Seal is ideal for equipment that is difficult and time-consuming to disassemble, such as large pumps, vertical pumps, and horizontal split case pumps. This proven, compact design can be used in a wide variety of equipment and process fluids.

The high performance split technology allows the 442 to operate from vacuum to high pressures. Its compact design allows for easy installation and a fit advantage on most equipment. Split, low-cost repair kits reduce ongoing maintenance costs even further. Designed with the installer in mind, the ball-and-socket O-Rings provide a quick and easy seal without the use of adhesives. Captive screws cannot fall out, making installation straightforward and reliable.

Note: The 442HP includes additional set screws, increasing the pressure capability of the seal to 30 bar g (450 psig).
