These reservoir-based seal support systems are designed for both API Plan 52 and 53A applications to support unpressurized and pressurized dual seals. Circulation of barrier fluid is normally achieved with a pumping ring (or optional circulating pump), and a range of heat exchangers can be packaged with the system — selection dependent on available plant utilities.
Crane Engineering recommends John Crane seals for many sealing applications throughout your facility. We've seen them be put to the test in harsh environments and difficult to seal applications, and succed. Their lines of single cartridge seals offer fast and easy installation for maintenance teams with little time for seal maintenance.
