A pump is provided including a housing and a plurality of diaphragm assemblies radially disposed within the housing, each diaphragm assembly of the plurality of diaphragm assemblies including a diaphragm. A drive element is configured to be eccentrically coupled to a rotating shaft motor to actuate the diaphragm for each of the plurality of diaphragm assemblies to draw fluid into or expel fluid from the diaphragm assembly. The drive element includes a first member and a plurality of second members, each second member of the plurality of second members being movably secured to the first member and disposed between the first member and the diaphragm of each of the plurality of diaphragm assemblies. During actuation of each diaphragm of the plurality of diaphragm assemblies, the corresponding first member and second member provide a continuously rigid radial coupling with the diaphragm.
