API PLAN 54
Product Description
-
API Plan 54 comes into two variety – either in
piping design or stand-alone tank design.
Piping design API Plan 54 takes external
barrier liquid from the plant header and
includes pressure control valve, strainer,
flow-meter, pressure gauge, temperature
gauge and fittings.
Stand-alone API Plan 54 consists of a tank of
150 L capacity, gear pumps with motors,
suction strainer, breather, pressure relief valve,
pressure control valve, accumulator, pressure
gauge, temperature gauge & flow meter.

Objective
- External source provides required pressure & flow which is used for cooling of the seal faces.
- It is used for very high temperature application like crude bottom pumps.
- This plan is used for the liquids which are highly flashing when they come into contact with atmosphere.
- It is used in applications where high flow rate of barrier liquid is required for heat removal from the seals faces.
Advantages
- Highly reliable API Plan for removal of heat generated across seal faces & heat soak.
- Barrier fluid has exceptional lubricating properties which results in extended MTBPM for the seal.
- When properly instrumented the system can safeguard the seal against pump upset conditions.
- Positively eliminates the leakage of harmful & fugitive emissions to the atmosphere.
- Can provide pressurized flow to multiple seal installation with one system to reduce costs.
- It is not constrained by nitrogen ingress into the barrier fluid as in API Plan 53A
Technical Features
- Piping design of API Plan 54 constitute pressure control valve designed to provide the required downstream pressure to the Seals
- Bypass line in piping design allow for maintenance of flow-meter Stand – Alone tank design
- Electric motor is started to the required pressure & flow rate of the barrier liquid
- Gear pump is designed for the required flow rate 5.Baffle plate provided in the tank for the smooth flow of barrier liquid return line
- Accumulator along with solenoid valves maintain barrier pressure in the seal chamber during pump upset condition or power cut off for few minutes
- Pressure relief valve releases any build-up pressure back to the tank.
- Pressure control valve in combination with flow-control valve provides the required pressure and flow to the mechanical seals
- Heat exchanger could be either water cooled in coil design or plate-type designed to the duty required based on the thermal design.
