Neptune Series MP7100 Mechanically Actuated Diaphragm Metering Pump

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
