NeptuneChemical Pump Co”s Series 7000 dia-Pump is a mechanically actuated diaphragm metering pump specifically designed for water and wastewater applications. The mechanical design of the Neptune Series 7000 eliminates the use of contour plates on the liquid side of the diaphragm. The straight-through valve and head design allows for improved flow characteristics. The pump is self-priming and provides solid performance when pumping chemicals such as sodium hypochlorite, which can off-gas. With a maximum capacity range from 15 to 300 GPH at 150 PSI, the Series 7000 is available in PVC, Kynar and 316 stainless steel liquid ends. All moving parts run submerged in oil for extended service. All models accept standard 56C frame motors and are available with integral motors.
