Abstract: A fluid pump for pumping fluidized materials comprises a motor, a material pump, and a closed-loop pressure hydraulic system interconnecting the motor and the material pump. The closed-loop hydraulic system further comprises a hydraulic pump, a pressure regulator, an impeller, and an expandable fluid reservoir. The motor includes an output to drive the hydraulic pump, which pumps hydraulic fluid throughout the closed-loop hydraulic system. As the hydraulic fluid flows throughout the closed-loop system, it passes through the impeller, which in turn drives the material pump to deliver the fluidized material from a material reservoir to an outlet valve for dispensing the material.

Abstract: Mobile chemical sprayers dispense liquid chemicals over a large area, such as a lawn or garden, in a short period of time. Individuals applying chemicals are not tethered to a fixed tank by a long hose, but can instead continuously move and apply chemicals simultaneously using a mobile chemical sprayer. This facilitates a more uniform distribution of chemical, and eliminates the need to spend time moving the tank or repositioning the hose.
