As mentioned in this previous blog post, AP Pump Saver 195 can be used to lubricate and protect single-component pumps. Now we’ll look at how it can be used in two-component pumps to reduce isocyanate contamination in the lube reservoir.
Recent field tests have proven that AP Pump Saver 195 rejuvenates and restores seals on the A-side of two-component proportioners. Seal deterioration is the main cause of isocyanate leaking into your pump lube reservoir. Healthy seals will stop this contamination. Simply empty your pump lube reservoir and replace the lube or DOP with AP Pump Saver 195.
