Jose: quite rare in the Americas - apparently a rear-mounted pump.
The big, red, boxey thing, with the handle, would be the Dump Valve; for filling Portable Tanks (Mobile Dams) by gravity.
Seeing as the Dump Valve is mounted at bottom of Water Tank; and the high Rear Hose-bed on top of the tank; must be quite a water-capacity - maybe 1500 Imperial Gallons of water [1800 US Gals; 6820 litres] on the single rear-axle.

Thanks for showing us an interesting rig.
