The Chem-Pro M MC-2 metering pump from Blue-White Industries is equipped with a variable-speed motor, offering smooth and quiet chemical dosing with no hard pulses. A full stroke every time prevents vapor lock. It can handle high-pressure applications up to 175 psi with a maximum feed rate of 50 gph. The pump is fitted with a Dia-Flex single-layer PVDF diaphragm that exhibits zero breakdown or delamination, reducing field maintenance and downtime. Additional features include an operator-friendly control panel with a protective, snap-on polycarbonate cover to protect the LCD screen and the touch pad from UV exposure and the elements. The display indicates fluid output in several measurement units, including mL/min and gpm. 714/893-8529; www.blue-white.com
