Abstract (en)

A pump comprising a housing (12) having a head carrying area (18), a motor (14) disposed within the housing (12), a rotor (17) rotated by the motor (14), and a pump head assembly (100) mounted to the head mount of the housing (12), the pump head assembly (100) being one of a piston head assembly (100) or a diaphragm head assembly. The head carrying area (18) is configured such that the piston head assembly (100) and the diaphragm head assembly may be interchangeably mountable thereon. The head carrying area (18) comprises a cylinder seat (36) surrounding an aperture (34) and a radially outward of the aperture (34). The sidewall (22) may also have a step (28). The cylinder seat (36) may be sized to receive a cylinder (118) of the piston head assembly (100) and the annular step (28) of the annular sidewall (22) may be configured to receive a diaphragm support ring of the diaphragm head assembly.
