MP7120-3N3

Chemical Metering, Diaphragm Pumps, Injection / Dosing, Mechanically Actuated, Metering, Wastewater Treatment

Features and Benefits
• Suction-lift exceeding 20 ft. (6 m) on water-like chemicals
• Heavy-duty, corrosion-resistant aluminum gearbox
• Finned gearbox design dissipates heat more efficiently than other designs
• Rugged bronze gears are quiet-running and provide long service life
• Oversize check valves improve performance and minimize friction losses
• Short stroke length reduces diaphragm stress and promotes longer diaphragm life
• 10:1 turndown via micrometer-type knob with high-contrast, easy-to-read scale
• Repeatable accuracy is ±2% at full scale (at constant hydraulic conditions)
• Rugged, PTFE-faced, pre-formed composite diaphragm with steel insert assures volumetric accuracy throughout the capacity range
• All models include standard NEMA 56C
• Superior performance when pumping chemicals such as sodium hypochlorite, which can off-gas
• Max capacity up to 286 gph (1,041 L/h)
• Max pressure up to 235 psi (16 bar)
• Automatic speed control with variable frequency or SCR drive options available
• Optional IEC motor adapter
