Hydraulic pump providing enhanced physical mobility

A method for implementing the installation of drywall taping, finishing, and texturing materials via an abrasive materials pumping apparatus comprising:

• mixing drywall compound within a reservoir;
• submerging a lower-most end of the pumping apparatus into the reservoir;
• connecting an application tool to a first end of a material supply hose;
• connecting a second end of the material supply hose to the pumping apparatus;
• connecting the pumping apparatus to a remote hydraulic pump system;
• activating a pump motor of the pumping apparatus, causing pressure to build within at least one material passageway within the pumping apparatus;
• the remote hydraulic pump system supplying hydraulic fluid to the pumping apparatus through a reciprocating valve leading to the pump motor;
• wherein hydraulic fluid pressure is preset through a relief valve on the remote hydraulic pump system;
• abrasive material flowing through passageways within the pumping apparatus due to the application of built pressure;
• abrasive material moving out of the pumping apparatus through an exiting port into the material supply hose;
• air exiting out of the pumping apparatus through an air output port into an independent air hose;
• wherein said material supply hose and said independent air hose are terminated by an application tool;
• the independent air hose supplying pneumatic pressure to the application tool;
• and
• a valve metering the abrasive material as the abrasive material exits the pumping apparatus into the material supply hose via at least one exiting port.
