The Evolve 55 is an evolutionary design of one our most popular and reliable pumps, the Maxim 50. With the help of our customers, we designed the Evolve 55 with improved performance and reliability in mind. First, we focused on improving the life and performance of the diaphragms by incorporating a patent pending diaphragm seal design along with our new Diffuser Head™ technology.

Second, we focused on decreasing the potential for leaks by improving head and body seals and by incorporating Perlast® sealing technology in the fluid ports, which were specifically developed to meet the demands of high purity, moderate pressure applications, such as semiconductor wafer processing, bio-analytical processing, and pharmaceutical processing.

Third, we focused on making improvements with cost as the driving factor. We worked with our suppliers to drive down costs and to improve our own manufacturing yields. In addition, the Trebor® team, along with our suppliers, developed a new method of manufacturing, called Precision Thermal Set Construction™, which combines molding and machining parts to allow for cost savings without compromising accuracy.
