Boiler Feed Seals

PPC’s experience with boiler feed applications is extensive. Boiler feed applications have been misunderstood for years. The optimum configuration for a boiler feed application is a high-pressure seal with a restriction bushing, multi-port injection, and an API Plan 23 heat exchanger. This allows for optimum cooling and maximum life on the mechanical seal. Multi Pass Cooling (API Plan 23) allows for maximum cooling in the mechanical seal stuffing box. The second choice would be an API Plan 21 with a heat exchanger coming from the discharge side of the pump to cool and raise the pressure in the stuffing box to increase the vapor margin. PPC can offer a plan to upgrade your existing seals with Lube Groove or Hydro Pad technologies at a reduced cost resulting in improved MTBF.
