110 Pump

High Purity Chemical Pump for Low Flow Chemical Circulation Applications. Many years of proven reliability make the Trebor® Model 110 pump an industry standard for lower flow, high purity chemical pumping applications. The Model 110 is an air-operated, double diaphragm pump with flow capacity up to 5.5 GPM and operates in fluids at temperatures up to 120°C. Using only virgin PTFE and PFA materials in the fluid path, the Model 110 is compatible with virtually all process chemicals. The center fluid cavity and internal air control valves make this one of the smallest pumps on the market for its capacity. Installation and maintenance is easy. As with all Trebor pumps, the 110’s simple and compact design utilizes few moving parts for improved reliability and low maintenance costs. Its non-metallic exterior makes it ideal for use in aggressive environments.
