Engineered Seal Systems

Engineered Environmental Control Systems (API Plans):

An essential element to the successful operation of mechanical seals is the right application of the appropriate environmental controls. Mechanical seals need to be kept cool, clean and lubricated, a mantra you will hear at any mechanical seal training seminar. API (American Petroleum Institute) has assembled and organized the plans numerically under its API 682 code for mechanical seals, to ensure that everyone is operating off a standard set of descriptions and nomenclature. The standardized plans may be further altered to each customer’s specific preferences (e.g. switches vs. transmitters). 

The environmental controls cover a broad range of offerings from simple flush plans, to seal reservoirs or forced fluid systems for dual seals, to highly engineered gas panel systems and controls for non-contacting and contacting seals.

PPC manufactures all of the relative support systems and environmental controls to optimize the life of your mechanical seals. Systems include a multitude of configurations. (ANSI, API, DIN, U and UM coded, CRN’s, etc). Typical system plans: 12, 21, 23, 32, 52, 53, 53B, 54, 55, 65, 72, 74, 75, and 76. We have standard systems and we custom manufacture to your specific specifications.

PPC can further assist you with the simple but critical, sizing of bushings for plan 21, 23, 32 and calculating the heat requirements for complex wet systems for dual seals (skid 54’s), and gas system requirements for dry running and lift off seals (contacting and non-contacting seals).

PPC Plan 53B

PPC’s API Plan 53B is a seal system utilizing a bladder accumulator to maintain continuous pressure on the seal without a constant external source. The system is coupled with a dual mechanical seal with the barrier fluid between the sets of faces pressurized greater than the process.

Multiple accessories are available including water and air-cooled heat exchangers sized for the application, pressure and temperature instrumentation, and built-in hand pumps with reservoirs to simplify maintenance.
