PR 52 and PR 53A Pump Seal Support Systems | John Crane

PR 52/PR 53A

Reservoirs

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 buffer/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.
