Chesterton introduces 442C cartridge split mechanical seal

Feb. 27, 2017 – ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton describes the 442C cartridge split seal as the latest innovation in mechanical split seal technology, combining “superior seal performance with the ease of installation of a cartridge seal.”

The split seal technology addresses the inherent limitations found in conventional cartridge split seal designs by minimizing installation complications and excessive leakage, says the company, adding that it offers easy installation and replacement without the need for teardowns. The 442C design also offers “maximum installation flexibility” with its short axial length and flexible gland positioning. According to Chesterton, the 442C simplifies split mechanical seal repair by using a standard spare parts kit, enabling users to lower inventory costs to maintain operations. The split seal can be installed without checking for face alignment or touching the sealing elements — the deal faces align themselves and do not have to be handled or worked, adds Chesterton.
