Pump Lubrication System - Graco Reactor 2 E-30 Operation

Pump Lubrication Lubrication System
Pump Pump Lubrication
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:
1. Follow Pressure Relief Procedure, page
2. Lift the lubricant reservoir (R) out of the bracket
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.
3. Drain the reservoir and flush it with clean
lubricant.
4. When the reservoir is flushed clean, fill with fresh
lubricant.
