Seal Monitoring Systems
Primary Seal Condition Monitoring Piping Plans are used to control the leakage from the primary mechanical seal faces and warn users when a primary seal failure has occurred. Flexaseal manufactures all API recognized types.
Flexaseal produces the following mechanical seal monitoring systems according to API specifications. Our mechanical seal support systems are made in the U.S.A. at our Texas facility.
API Plan 65
Our MP65 system is in line with API 682 Piping Plan 65 and is made to collect leakage from the primary seal. The system detects and warns the operator about excessive leakage from the primary seal. This API piping plan is designed for use on generally non-hazardous process fluids that are condensing.
API Plan 72
Our MP72 system is designed for buffer gas injection behind the primary seal and aligns with API 682 Piping Plan 72. The injected buffer gas sweeps and dilutes volatile emissions. Model MP72 is intended to operate in tandem with Piping Plan 76 or 75.
API Plan 75
The MP75 seal monitoring system aligns with API 682 Piping Plan 75. This model is designed to collect primary seal leakage and Plan 72 buffer gas. The system detects excessive leakage from the primary pump seal and warns the operator. This API piping plan is made for use on process fluids that are condensing or non-condensing.
API Plan 76
Our MP76 system for seal monitoring aligns with API 682 Piping Plan 76. The system is designed to collect Plan 72 buffer gas Primary Seal Leakage. The system will identify excessive leakage from the primary seal and alert the operator. This API piping plan is made for use on non-condensing process fluids.
