A system for reducing wear includes a receptacle having at least one wall and a floor for holding material within the receptacle. An opening is located in the floor for accessing material held in the receptacle. A sliding frame is located above and parallel to the floor for agitating material held in the receptacle. At least one component is included inside the receptacle to reduce wear on the floor and/or sliding frame, and/or a wear indicator is located outside of the receptacle to monitor wear on the floor and/or the sliding frame.

Wear system for receptacle with sliding frame

A pump system for pumping a viscous material that includes N positive displacement pumps, where N is an integer greater than two, and a hydraulic drive. Each pump has an inlet and an outlet therefrom, and a pair of cylinders each with a piston movable in a reciprocating stroke cycle therein. The hydraulic drive is connected to the N positive displacement pumps to reciprocate the pistons within the cylinders. The stroke cycle includes a discharging stroke and a filling stroke. The discharging stroke and the filling stroke of the N positive displacement pumps are staggered from one another by 1/N stroke positions such that no two pumps have pistons in the same stroke position at the same time.

Multi-pump sequencing

A method for clearing obstructions in a silo having a reciprocating frame uses an obstruction clearance mode. The method includes driving at least one frame in a reciprocal motion across a silo floor until sensing an indication that at least one frame has encountered an obstruction. Upon sensing the indication of obstruction, an obstruction clearance mode is initiated in an attempt to clear the obstruction.

Obstruction clearance mode for silo with reciprocating frame

A silo for storing viscous material such as sludge, the silo comprising a floor and a perimeter wall connected to the floor, is disclosed. The silo further comprises a moveable frame adjacent to the floor wherein the frame defines an area less than the area of the floor, and an opening in the floor. A crosspiece having opposite ends mounted to generally opposing portions of the perimeter wall is provided within the silo adjacent to the moveable frame. The crosspiece contains a surface facing the floor and is positioned adjacent to the frame. The crosspiece further comprises one or more diverter portions connected to the crosspiece which extend from the floor facing surface of the crosspiece towards the floor.
