Fluid volatility and toxicity of the uid must be such that the leakage to the

atmosphere or disposal does not impose an environmental problem.

1. The uid should have an initial boiling point at least 50°F above the

temperature to which it will be exposed.

2. The uid should not have a ash point higher than the service temperature

if oxygen is present.

The uid 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, parafnic-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 ushed with clean uid 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.
