Claim:
A mobile pump system comprising: a wheeled trailer including a trailer frame, wherein the trailer is adapted to transport the mobile pump system from one location to another; a power source mounted to the trailer; a hydraulic fluid supply system mounted to the trailer and powered by the power source; an adjustable pipe system including a discharge pipe section, an intake pipe section and a swivel section mounted to the trailer frame and coupled between the intake pipe section and the discharge pipe section, wherein the swivel section: allows the discharge pipe section to be pivoted, independently of the intake pipe section, about a discharge pipe pivot point that is fixed with respect to the trailer; and allows the intake pipe section to be pivoted, independently of the discharge pipe section, about an intake pipe pivot point that is fixed with respect to the trailer frame; a submersible hydraulic pump mounted to the intake pipe section and driven by the power source; a first extensible pivot arm actuated by a first hydraulically actuated pivot cylinder, wherein the first pivot arm is pivotally coupled to the discharge pipe section so that as the first pivot arm is extended and retracted the discharge pipe section pivots about the discharge pipe pivot point, whereby the discharge pipe section can be positioned at various angles with respect to the trailer frame; and a second extensible pivot arm actuated by a second hydraulically actuated pivot cylinder, wherein the second pivot arm is pivotally coupled to the intake pipe section so that as the second pivot arm is extended and retracted the intake pipe section pivots about the intake pipe pivot point, whereby the intake pipe section can be positioned at various angles with respect to the trailer frame; wherein the hydraulic fluid supply system includes a control valve assembly configured to control and maintain the supply of hydraulic fluid in the hydraulic cylinders.
