At WEFTEC, Neptune will be showcasing its Series 7000 mechanically actuated diaphragm metering pump that has specifically been designed with water and wastewater applications in mind. 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 Series 7000 is self-priming, provides superior performance, and has a maximum capacity range up to 300 gph (1,135 L/h) at 150 psi.

Neptune’s PZ Series electronic diaphragm metering will also be featured at WEFTEC. PZ Series pumps have numerous designed in features, making them ideal for various product applications at flow rates from .01 to 20 gph. Neptune designed the PZ Series pumps with a variety of different controls. PZ pumps operate on a manual control that produces speed ranging from 15 to 300 strokes per minute. A variety of liquid-end materials are available.

Neptune will also exhibit its industry-leading Series 500 hydraulically actuated metering pumps. The Series 500 pumps feature EZE-CLEAN valve cartridges that can be removed for cleaning without disturbing the piping to the pump and a Variable Oil By-pass stroke adjustment that allows for better valve performance than traditional variable-linkage designs. Series 500 pumps are manually adjustable from 10% to 100% of capacity via micrometer dial or flow may be controlled automatically by electric stroke positioners or motor speed controls. Series 500 pumps have capabilities to 80 gph (302 L/h) simplex and 160 gph (605 L/h) duplex at pressures up to 3,000 psi (210 KG/cm).
