The ChemPro M diaphragm metering pump from Blue-White Industries is suited for injection of aggressive and/or viscous chemicals. Equipped with a variable-speed DC motor, it offers smooth and quiet chemical dosing, with no hard pulses. A full stroke every time avoids lock. It’s fitted with a DiaFlex single-layer PVDF diaphragm for chemical compatibility, allowing for an all-PVDF pump head. The display indicates output in several optional measurement units, such as mL per minute or gpm. Intelligent electronics permit connection to SCADA systems and other remote controllers for dosing control. It has upgradeable firmware, a diaphragm failure detection alarm system, UV-protective LCD cover, turndown ratio of 200-to-1, feed rates to 40 gph, pressures to 175 psi, a NEMA 4X washdown/IP66 housing, and is NSF Listed Standard 61 for drinking water. 714/893-8529; www.blue-white.com.
