Neptune’s Series MP7000 mechanically actuated diaphragm metering pump offers a low-flow version of the Series MP7100 metering pump. It features the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm, and reduces the potential for gearbox oil to contaminate the process. Its finned gearbox dissipates heat created during operation, oversized check valves improve performance and minimize friction losses, and rugged bronze gears provide quiet running and long service life. Flow is improved by a straight-through flow design of the liquid end and the elimination of the contour plate. The pump offers capacities to 27 gph at operating pressures up to 235 psi, and includes a 10-1 turndown ratio via micrometer-type knob with an easy-to-read scale. It is available with a self-loading micrometer that prevents drift, and an optional automatic speed control with variable frequency or SCR drive. All models include a standard 63 IEC motor adapter. 215/699-8700; www.neptune1.com
