SealBoss R70 Pump Flush is our universal pump cleaner and conditioner to be used with all of the pumping equipment offered by SealBoss.
This product is a proprietary blend of lubricants and conditioners to be used as part of your cleaning process. Now, before we get into that, I just want to also introduce the five and the one gallon packaging based on whatever size jobs you guys may have.
So, back to the idea of being part of the cleaning process. It’s very simple. We have a vast array of pumps ranging from polyurethane injection pumps to structural epoxy injection pumps, and of course, our JointMaster Pro 2 joint fill pump that pumps polyurea in all cases, what you’re going to want to do is attack the cleaning process in two very easy but distinct steps.
And here they are:
Your first step is going to be to take a solvent. We recommend xylene here at seal boss and run that solvent through the machine so as to go ahead and Purge.
How do I know when I’m actually purged?
And the answer is very simple as you run your xylene through the machine.
When you see fresh or clear looking xylene coming out of the end of the manifold or the applicator of the pump that you’re actually cleaning. You’ve met the purge condition. It is at that point where the R70 comes into play.
What we’re going to do is take a small amount of Pump Flush , because when you think about the volume needed all, you’re really going to be doing with our 70 is running a small amount through the system behind that solvent flush — xylene flush — to get rid of any xylene that could be left in the system.
What’s the system?
The system is the pumping mechanism, any cylinders, any Pistons, the hose itself, the applicator, and the manifold. Once we chase any residual solvent xylene again is what we recommend out by using our R70 Pump Flush.
Now, we’re clean!
A couple more words on that. You can either store that unit if you know, for example, you’re not going to be doing any injection, you’re not going to be doing any joint filler for months on end. You can go ahead and store it, winterize it with R70 Pump Flush left in it.
You can also go ahead and be ready for the next days worth of shooting Either the urethanes, the epoxies, the polyurea, and what you’ll do is you’ll fill your tanks normal, and then you’ll just purge out any remaining our R70 with the product for that next live install that you have, and you’re ready to go.
R70 Pump Flush lubricates, conditions and preserves the key components of your machine for the long haul.
SealBoss offers a comprehensive selection of polymer dispensing equipment and accessories including professional injection and floor repair joint fill pumps, injection ports, hoses and applicators.
