Description

The UnitedBuilt 6V4700 VisionTank™ On/Off-Road Water Truck combines a UnitedBuilt 4,700-gallon steel tank with a 2027 Peterbilt 548 tandem-axle chassis rated at 66,000 pounds GVWR. A 330-horsepower PACCAR PX-9 engine and Allison 3500-RDS automatic transmission support construction dust control, road maintenance, compaction support and jobsite water delivery.

The modified-trapezoid VisionTank™ profile improves rearward visibility. The tank features 3/16-inch ASTM A36 steel construction, curved and fully welded baffles and heads, a full-length reinforced belly plate, heavy-duty cradle runners and a six-point mounting system.

A UnitedBuilt M3ZRMS 4x3 centrifugal pump rated at 750 GPM is driven by a Muncie A20A1010HX31XPX clutch-shift PTO through a balanced driveline. The 131% PTO ratio with the Allison 3500-RDS supports pump-and-roll spray operation while the truck is moving.

This Fully Loaded configuration includes six independently controlled spray valves, Schedule 40 stainless-steel plumbing, an Elkhart Nitro HD water cannon with joystick control and a Coxreels 1185-1124E electric-rewind hose reel, 1-1/2-inch by 50-foot. Cab-mounted controls provide independent spray-valve operation. Suction-fill equipment is not included and is available as an optional installation when ordering.
