Boom mounted pump

A liquid pumping vehicle comprising:

• a frame;
• wheels mounted on the frame proximate a first end of the frame;
• a platform mounted on a swivel, the swivel rotatably mounted on the frame centered over the wheels proximate the first end of the frame, the platform rotatable about a vertically oriented rotation axis relative to the ground;
• an articulated boom mounted on the platform proximate a first end of the boom;
• a first liquid pump mounted on the boom proximate a second end of the boom, the first liquid pump immersible in a liquid reservoir for pumping liquid out of the reservoir;
• a second liquid pump mounted on the platform, the second liquid pump in fluid connection with a fluid conduit through which the first liquid pump pumps the liquid, the fluid conduit situated exterior to the boom and passing from one side of the boom to another side of the boom at articulation points on the boom;
• an engine mounted on the platform, the engine operably connected to the first liquid pump and the second liquid pump for operating the first and second liquid pumps, the engine situated
• so that the rotation axis of the platform is between the boom and the engine and
• so that a first turning moment created on a first moment arm relative to the rotation axis by weight of the engine and other components on an engine-side of the platform is offset under operational conditions of the pumping vehicle by a second turning moment created on a second moment arm relative to the rotation axis by weight of the boom and other components on a boom-side of the platform;
• and,
• a flow discharge outlet, the flow discharge outlet connected to the second liquid pump by the fluid conduit through which the liquid is pumped by the first and second liquid pumps from the liquid reservoir to the flow discharge outlet.
