Abstract: Modular mechanically driven diaphragm pump features are presented herein. Such a diaphragm pump can include a motor, a drive mechanism, and a coupling mounted on a wheeled frame. A diaphragm pump can be mounted to the coupling by forming mechanical static and dynamic connections to brace a housing of the diaphragm pump relative to a drive rod which is moved by the drive mechanism to operate the pump. These mechanical static and dynamic connections can be broken to dismount the pump for replacement or servicing. In some cases, a gas charge can be introduced on the non-working fluid side of the diaphragm to boost performance and/or a dampener can be integrated into the housing of the diaphragm pump and mounted/dismounted with the diaphragm pump.

Abstract: This disclosure concerns a check valve that prevents over compression of a gasket. The check valve comprises a valve housing, a valve cover, and a gasket that seals between the valve housing and the valve cover. A ball fits within the valve housing. The check valve further comprises a ball stop that limits compression of the gasket as the valve cover is tightened with respect to the valve housing. The ball stop serves as a standoff between the valve housing and the valve cover that allows some compression of the gasket as the valve cover is tightened with respect to the valve housing, but at some degree of tightening the incompressible engages both the valve cover and the valve housing to prevent further tightening. Over-compression distorts the gaskets, possibly compromising its sealing function and possibly damaging the gasket.

Abstract: A method of displacing fluid includes pulling a pump displacement member through a suction stroke with a pull, the pull configured to transmit only tensile forces to the fluid displacement member. A working fluid disposed in an internal pressure chamber drive the fluid displacement member through a pumping stroke. The pull is prevented from transmitting any compressive forces to the fluid displacement member, such that the pull does not drive the fluid displacement member through the pumping stroke.

Abstract: A drive system for a pump includes a housing, first and second fluid displacement members, and a reciprocating member configured to mechanically displace the first and second fluid displacement members through respective suction strokes. The housing and fluid displacement members define an internal pressure chamber configured to be filled with a working fluid having a charge pressure. The internal pressure chamber is configured such that the working fluid simultaneously exerts the charge pressure on the first and second fluid displacement members.
