Flowserve Seal Support Reservoir - Manual (Page 6)

Fluid volatility and toxicity of the fluid must be such that the leakage to the
atmosphere or disposal does not impose an environmental problem.
1. The fluid should have an initial boiling point at least 50°F above the
temperature to which it will be exposed.
2. The fluid should not have a flash point higher than the service temperature
if oxygen is present.
The fluid should be able to meet the minimum 3-year continuous seal operation
criteria without adverse deterioration. It should not form sludge, polymerize or
coke after extended use.
1. For hydrocarbon streams, paraffinic-based high purity oils having little or no
additives for wear/oxidation resistance or synthetic based oils have been
used successfully.
2. Anti-wear/oxidation-resistant additives in commercial turbine oils have been
known to plate out on seal faces.
Installation
1. The reservoir is mounted vertically not more than 3 feet (0.9 meters) from
the seal gland to the vertical centerline of the reservoir. The bottom of the
reservoir is mounted 18 to 24 inches (45.7 to 61 centimeters) above the
horizontal centerline of the pump.
2. It is highly recommended that the reservoir be flushed with clean fluid prior
to equipment start-up to remove any foreign matter from the system.
3. All lines from the seal cavity to the reservoir must slope upward at all points.
The upward slope should be a minimum of 1/4 inch per foot with all bends
being large radius. The minimum size for tubing should be 3/4 inch
diameter. Tubing is recommended.
4. Connect the supply connection (lower seal connection on the reservoir)
to the bottom (inlet) gland connection (BI - inlet).
5. Connect the return connection (upper seal connection on the reservoir)
to the upper (outlet) gland connection (BO - outlet).
6. If the reservoir is equipped with cooling coils, connect water lines to the coil
connections on the bottom of the reservoir.
7. Remove all plastic shipping plugs and properly seal or attach piping
with metal connections.
8. Connect wiring to any instruments included with the system such as a
pressure switch/transmitter or level switch/transmitter.
