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.
