ABSTRACT:
Apparatus10discloses a submersible hydraulic powered pump for removing matter such as liquid, abrasive particulate, slurries or mixtures12, from a sump or container. The pump has a housing14with an integral stand16projecting therefrom comprised of a plurality of legs extending to a base plate that will keep the pump spaced away from the ground and gauge the size of matter56allowed to enter the pump. Positioned within the housing base is an ingress aperture serving as the intake50for flowable matter into a chamber having an impeller assembly52driven by a hydraulically powered motor18. The impeller assembly52comprises a plurality of perforated plates and an impeller plate38that allows for the release of trapped air through the impeller assembly's apertures at46to prevent the buildup of air and unwanted pressure gaps within the pumping lines also known as “air lock.” Additionally, the impeller plate38and impeller blades have an increased clearance60from the sides58of the housing14to prevent jamming of the impeller due to large particulate matter becoming lodged therebetween during rotation and also to more efficiently induce centrifugal motion about the drawn matter contained in the housing.
