Series MP7000 Mechanically Actuated Diaphragm Metering Pump

The Series MP7000 Mechanically Actuated Diaphragm Metering Pump is the low-flow version of the MP7100 metering pump. The MP7000 incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm and eliminates the potential for gearbox oil to contaminate the process since it has an oil free gearbox design. The result is a pump design that provides reliable and accurate dosing.

  • 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
  • Superior performance when pumping chemicals such as sodium hypochlorite, which can off-gas
  • Excellent suction lift for water-like chemicals
  • Capacities to 27 gph (102 lph)
  • Operating pressures 235 psi (16 bar)
  • 10:1 turndown via micrometer-type knob with high-contrast, easy-to-read scale
  • Repeatable metering accuracy is ± 2% of full scale (at constant hydraulic conditions)
  • Operational automatic speed control with variable frequency or SCR drive
  • All models include standard 63 IEC motor adapter
