Abstract: Methods and systems include a check valve including a valve body formed from a resilient material, the valve body having an inlet side and an outlet side. The valve body includes a rim forming an outer periphery of the valve body, and a hinge section comprising an annular groove formed on the inlet side of the valve body radially inward of and adjacent to the rim. The valve body also includes a plurality of lips formed at a center of the valve body by one or more slits extending radially outward from the center of the valve body towards the hinge. The hinge section is co-planar with the plurality of lips when in a closed position.

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.

Abstract: A tightening device for applying a preload to a fastening element, wherein the fastening element is suitable for fastening a diaphragm pump head part to a drive system for impressing movement on a diaphragm of the diaphragm pump head part in a device for conveying fluid. The tightening device has a support with support surface for supporting a bearing surface of the fastening element, wherein the support has a threaded bore through which a screw element penetrates. The screw element has a contact surface at its front end, wherein the contact surface of the screw element and the support surface of the support face opposite directions, and the distance between the contact surface of the screw element and the support surface of the support can be changed by screwing in or unscrewing the screw element.
