ABSTRACT:
A pumping system for conveying animal waste from a livestock housing to a remote storage area includes a hopper which is conveniently located in a pit adjacent to a chain driven barn cleaner or the like, a vertically oriented upwardly open pumping chamber in communication with the hopper and a hydraulically operated ram which travels vertically through the hopper into the pumping chamber to force the waste through a reducer and discharge pipe to a storage pit or area located remote from the livestock housing. Other features include a vacuum relief valve located in the pumping chamber or ram to release the vacuum on the return stroke of the ram and thus, reduce the power required to move the ram to its retracted position. The vacuum relief valve also eliminates the need in some installations for a check valve to prevent reverse flow of manure into the hopper from the storage pit.
