Disclosed are pumps designed to make priming more efficient and therefore reduce priming time. The disclosed pumps include one or more deflection structures that prevent fluid moving through a diffuser of the pump from continuing in a circular path and instead divert the fluid in a different direction that leads directly to an outlet of the pump. This deflection reduces air bubble accumulation inside the pump while priming and makes it easier for air to escape through the pump outlet. Making it easier for air to escape the pump outlet ultimately allows air to escape the pump faster during priming, reducing back pressure caused by trapped air pockets inside the pump and improving priming performance.

Motor housings and shrouds are detailed. Inlets of the shrouds may be included on any or all portions of their peripheries (as well as on rears of shrouds if desired). Air hence need not necessarily be drawn wholly linearly into the shrouds, permitting the shrouds to abut, or at least be closely proximate, other objects without materially diminishing air flow into the shrouds. Moreover, plates within the shrouds may be positioned so as to create torturous paths through which the air must travel. Channeling air through these torturous paths helps reduce noise as the air moves to the fans.
