Abstract
A pumping system includes a first chamber and a second chamber to receive filtered medium. The pumping system includes a first motor assembly and a second motor assembly operably coupled to the first chamber and the second chamber, respectively. The first motor assembly and the second motor assembly each includes a pair of vacuum motors arranged back-to-back so that one of the vacuum motors operates to generate a negative pressure force on the chamber and the other vacuum motor operates to generate a positive pressure force on the chamber. The first motor assembly and the second motor assembly work together to alternate between siphoning material having one or both a fluid and a solid into one of the chambers and ejecting siphoned debris from another chamber.
