CAT PUMPS® has added several new Flushed Pump Models to its line.  These Flushed Pumps have proven to significantly extend seal life and reduce maintenance costs when pumping high temperature and low lubricity liquids.

These new C-version flushed pump models 3521C, 3531C and 3541C are available with a 316SS cast head offering strength and corrosion resistance.  The special porting in the inlet manifold permits an external flush between the Lo-Pressure and Hi-Pressure Seals or V-Packings. This flush provides cooling and added lubrication for the seals. As a side feature, the flushed pumps capture any leaking that might occur as the seals begin to wear in the circulating flushing liquid, avoiding external leaks and assuring a safe work environment
