Abstract
Pump assemblies are disclosed that have a magnetically driven pump-head subassembly and a pump-driver subassembly coupled thereto, wherein the pump-driver subassembly includes a pump-driver enclosure. The pump-head subassembly comprises a rotatable magnet contained in a magnet cup extending into the pump-driver enclosure. The pump-driver subassembly has a printed circuit board (PCB) in the pump-driver enclosure and a stator mounted to the PCB. The stator coaxially surrounds the magnet cup. The magnet cup has a distal-end wall. The printed circuit board includes a stator-driving circuit and at least one signal-processing circuit. The PCB defines a void relative to the distal-end wall that exposes at least half the distal-end wall. The pump-driver enclosure has an aspect ratio of no greater than one (unity).
