Abstract (en)
[origin: US2015118078A1] A diaphragm pump includes a diaphragm cartridge assembly. The diaphragm cartridge is a self-contained unit having a diaphragm defining a pumped fluid side and a hydraulic fluid side and a seat receiving the hydraulic fluid side of the diaphragm and having a center opening. A biasing rod mounts to the diaphragm on the hydraulic fluid side and extending through the opening of the seat. A valve guide at an extended end of the biasing rod and a valve spool slidably mounts on the valve guide. A biasing element engages the seat and the valve guide. The pump may also include valve cartridges including a combined inlet check valve and discharge check valve.
