The Maxim 50 is our most widely used pump across several industries because of its reliability and control features. The pump was designed to withstand highly aggressive chemical applications and the design was put head to head with competitor pumps in several processes to prove its performance. The proof of the study was that the Maxim 50 could withstand wear and chemical attack in chemical solutions that typically form crystals or suspend solids, which shorten the life of most pumps. In addition, the unique construction eliminates the need for O-ring seals.
