Abstract
A tile flood pump for attachment to a tile or drain pipe and pumping water from a field. The pump includes a pump housing, a flange bolted to the tile and an impeller housing enclosing one or more, lower rotating impellers, and extending into the pump housing for pumping water from the field through the impeller housing and the tile. A flapper valve can be provided on the intake end of the pump housing to facilitate flow of water through the pump housing and the tile. A shaft housing extends into the pump housing for enclosing a drive shaft that mounts the lower impeller(s) and connects to an external drive system. A shaft housing extension is removably fitted into the shaft housing for enclosing an upper impeller to flood and cool the upper marine and load bearings which carry the impeller shaft, upon which the upper impeller is mounted.
Claims6
A pump for coupling to a drive mechanism and a pipe and pumping water from a first location through the pipe to a second location, said pump comprising a pump housing having an intake end at the first location and a connecting end adapted for coupling to the pipe;
- an impeller housing extending into said pump housing intermediate the ends of said pump housing;
- a shaft housing extending from said pump housing intermediate the ends of said pump housing, said shaft housing positioned substantially in alignment with said impeller housing;
- a shaft housing extension removably provided in said shaft housing;
- an impeller shaft journalled for rotation in said shaft housing, said shaft housing extension and said impeller housing, said impeller shaft connected to the drive mechanism and extending through said pump housing;
- at least one lower impeller fixed to said impeller shaft in said impeller housing;
- and at least one upper impeller fixed to said impeller shaft in said shaft housing extension for pumping water from the first location through said impeller housing and said pump housing and through the pipe to the second location and through said shaft housing and said shaft housing extension, responsive to operation of the drive mechanism and rotation of said impeller shaft and said lower impeller and said upper impeller.
