Abstract
An assembly for a diaphragm pump includes: a body defining a plurality of diaphragm chambers spaced apart about a body axis, wherein each diaphragm chamber defines a membrane opening, an inlet chamber in fluid communication with each diaphragm chamber, and an outlet chamber in fluid communication with each diaphragm chamber; and a plurality of flexible membranes that each comprise an outer edge, wherein the body is configured to clamp the outer edge of each membrane along a corresponding membrane opening to seal a corresponding one of the diaphragm chambers; wherein the membranes are configured to deflect substantially in parallel to the body axis to suction fluid into each diaphragm chamber from the inlet chamber and discharge fluid from each diaphragm chamber into the outlet chamber; wherein each membrane comprises a coupling section configured to couple the membrane to a pump drive and arranged along a diaphragm axis that extends in parallel to the body axis, and a deflection section arranged radially outwardly from the coupling section and configured to deflect in response to movement of the pump drive; and wherein movement of the coupling section radial to and about the diaphragm axis is restricted to suppress movement of the deflection section radial to and about the diaphragm axis.
