Apparatus 10 discloses a submersible hydraulic powered pump for removing matter such as liquid, abrasive particulate, slurries or mixtures 12, from a sump or container. The pump has a housing 14 with an integral stand 16 projecting 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 matter 56 allowed to enter the pump. Positioned within the housing base is an ingress aperture serving as the intake 50 for flowable matter into a chamber having an impeller assembly 52 driven by a hydraulically powered motor 18. The impeller assembly 52 comprises a plurality of perforated plates and an impeller plate 38 that allows for the release of trapped air through the impeller assembly's apertures at 46 to prevent the buildup of air and unwanted pressure gaps within the pumping lines also known as "air lock." Additionally, the impeller plate 38 and impeller blades have an increased clearance 60 from the sides 58 of the housing 14 to 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.
