The Neptune Series 7000 "dia-PUMP" is a mechanically actuated diaphragm metering pump designed for water, wastewater and process applications.
The mechanical design eliminates the use of contour plates on the liquid side of the diaphragm. The simple, straight through valve and head design allows improved flow characteristics.
