The mechanical design of the Series 7000 eliminates the use of contour plates on the liquid side of the diaphragm while the simple, straight-through valve and head design allows for improved flow characteristics. The metering pumps are self-priming, provide superior performance, and have a maximum capacity range up to 300 gph (1,135 l/h) at 150 psi.

Neptune will also be featuring its PZ Series electronic diaphragm and Series 500 hydraulically actuated metering pumps. PZ Series pumps have numerous designed in features, making them ideal for various product applications at flow rates from 0.01 to 20 gph, the company says. PZ pumps operate on a manual control that produces speed ranging from 15 to 300 strokes per minute with a variety of liquid-end materials are available. In addition, the Series 500 pumps feature EZE-Clean valve cartridges that can be removed for cleaning without disturbing the piping to the pump. Series 500 pumps have capabilities to 100 gph (302 l/h) simplex and 160 gph (605 l/h) duplex at pressures up to 3,000 psi (210 kg/cm).

Neptune will also highlight its industry-proven line of Abaque peristaltic (hose) pumps. The Abaque line is available in nine different models/sizes with flow rates ranging from 0.07 to 211 gpm (0.015–48 m3/hr).
