The Series 7000 dia-Pump is a mechanically actuated diaphragm-metering pump specifically designed for water and wastewater applications. The mechanical design eliminates the use of contour plates on the liquid side of the diaphragm, and the simple, straight-through valve and head design allows for improved flow characteristics. Pumps have maximum capacity range from 15 to 300 gal per hour at 150 psi.
