Purpose

The Neptune Series MP7100 is a mechanically actuated diaphragm metering pump engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs.

Benefits

  • Heavy-duty, corrosion-resistant, aluminum gearbox

  • Gears operate in an oil bath for longer life

  • 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

  • Suction-lift exceeding 20 ft. (6m) on water-like chemicals

Features

  • Capacities to 275 gph (1041 lph)

  • Operating pressures to 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)

  • Rugged, PTFE-faced, pre-formed composite diaphragm with steel backing plate assures volumetric accuracy throughout the capacity range

  • Pump capacity can be easily adjusted while pump is running

  • Lockable micrometer knob prevents drift

  • Optional automatic speed control with variable frequency or SCR drive

  • All models include standard NEMA 56C or an optional IEC motor adapter
