Abstract
A dual-piston pump or similar material handling device includes a hopper assembly for storing material that is to be delivered to the device, and a transfer assembly between the hopper assembly and the frame of the device. The hopper assembly is supported for pivotal movement about a horizontal axis between a use position and a cleaning position, and the transfer assembly is supported for axial movement along a vertical axis and for pivotal movement about the axis so that it too may be moved to a cleaning position exposing the material handling device for cleaning.
