ABSTRACT:
An improved manure transfer system is disclosed. A collection hopper is located at a first location, preferably within a building, for collecting manure and animal waste products from the building. A piston pump apparatus directs and forces the collected manure through a pump cylinder into a below-grade transfer conduit that carries and deposits the manure through a discharge outlet located at a remote, second location. Means for bypassing the pump piston and cylinder are provided for accessing the transfer conduit enabling safe servicing and maintenance of the system. Isolation means are provided at the conduit discharge outlet for isolating the outlet from accumulated manure at the second location.
