Purge the System
Immediately after injection work is completed, remove as much injection resin as possible from the hopper, pump, hoses, shutoff valve, and applicator.
Do not begin the flushing process until the pump, hoses, and applicator have first been thoroughly purged of remaining injection resin.
Flush the System
When necessary, use a compatible solvent in the quantities required to dissolve and displace residual resin from the pump, hoses, shutoff valve, and applicator.
Pump the solvent through the complete system and discharge the contaminated material into an appropriate waste container. Do not recirculate solvent or resin-contaminated cleaning fluid.
Solvent should not remain inside the pump, hoses, seals, gaskets, or applicator. Immediately follow the solvent flush with sufficient SealBoss R70 Pump Flush & Cleaner to completely remove and displace all remaining resin and solvent from the system.
Continue pumping R70 until the discharged fluid is clean and free of visible resin or solvent contamination.
Recirculate and Condition
After the resin, contaminated cleaning fluid, and solvent have been removed, add clean SealBoss R70 Pump Flush & Cleaner.
Recirculate the clean R70 through the pump, hoses, shutoff valve, and applicator for a minimum of five minutes.
During recirculation, operate the pump at an elevated pressure setting and rapidly open and close the shutoff valve several times. This creates pressure fluctuations and high-velocity flow that help remove residual material from internal pump components, valves, fittings, and hoses.
Never recirculate visibly contaminated, resin-rich, or discolored cleaning fluid. Recirculation should begin only after clean R70 is flowing from the system.
A residual amount of clean R70 may remain in the pump and hoses during storage to lubricate and condition internal components.
Important Cleaning and Storage Requirements
- Clean the pump immediately after use.
- Never use water to clean, flush, or test a chemical injection pump.
- Observe the injection resin’s stated pot life at all times.
- Purge catalyzed polyurethane resin before extended work interruptions.
- Do not pump cured resin, partially cured resin, or surface skin into the pump.
- Never allow solvent to remain in the pump or hoses during storage.
- Use only cleaning products that are compatible with the pump, hoses, seals, gaskets, valves, and applicator.
- Dispose of resin, solvent, and contaminated cleaning fluid in accordance with applicable regulations.
