发明名称 Portable drywall joint compound pump station
摘要 A portable drywall joint compound pump station includes a pneumatic pump for pumping joint compound from a mud container. The pump has an inlet and an outlet, and is supported by a frame at a location above the bottom of the container. An intake tube depends from the pump inlet and has an inlet port located proximate to the bottom of the container when the station is in use. A valve is provided for controlling a supply of compound air to power the pump. The frame has four legs and includes mounting brackets that are used to mount the pump to the legs such that the pump resides substantially within an imaginary peripheral surface containing outer edges of the legs to form a protective cage around the pump.
