    Abstract: FIG. 1 is a first isometric view of a control box for a displacement pump;
    FIG. 2 is a second isometric view of the control box;
    FIG. 3 is a third isometric view of the control box;
    FIG. 4 is a fourth isometric view of the control box;
    FIG. 5 is a top plan view of the control box;
    FIG. 6 is a bottom plan view of the control box;
    FIG. 7 is a front elevational view of the control box;
    FIG. 8 is a left side view of the control box; and,
    FIG. 9 is a right side view of the control box.
    The broken lines in the Figures are represent portions of a control box for a displacement pump and of a displacement pump and form no part of the claimed design.

    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: A drive system for a pump includes a housing defining an internal pressure chamber, a working fluid disposed within and charging the internal pressure chamber, and a reciprocating member disposed within the internal pressure chamber. A fluid displacement component has first and second surfaces. The first surface is configured to contact the working fluid and the second surface is configured to contact the process fluid. The area of the first surface is greater than the area of the second surface. A pull extends between and connects the reciprocating member and the fluid displacement component. The pull mechanically transfers a pulling force from the reciprocating member to the fluid displacement component.
