Pump Lubrication System

Check the condition of the ISO pump lubricant daily.

Change the lubricant if it becomes a gel, its color

darkens, or it becomes diluted with isocyanate.

Gel formation is due to moisture absorption by the pump

lubricant. The interval between changes depends on the

environment in which the equipment is operating. The

pump lubrication system minimizes exposure to

moisture, but some contamination is still possible.

Lubricant discoloration is due to continual seepage of

small amounts of isocyanate past the pump packings

during operation. If the packings are operating properly,

lubricant replacement due to discoloration should not be

necessary more often than every 3 or 4 weeks.

To change pump lubricant:

TI10970a

TI10969a

1. Follow the Pressure Relief Procedure, page 25.

2. Lift the lubricant reservoir (LR) out of the bracket

(RB) and remove the container from the cap.

Holding the cap over a suitable container, remove

the check valve and allow the lubricant to drain.

Reattach the check valve to the inlet hose. See FIG.

10.

3. Drain the reservoir and flush it with clean lubricant.

4. When the reservoir is flushed clean, fill with fresh

lubricant.

5. Thread the reservoir onto the cap assembly and

place it in the bracket.

6. The lubrication system is ready for operation. No

priming is required.
