  • Impellers, casings, and wear rings

Each part is engineered to fit, built to last, and designed specifically for water trucks.

 

UnitedBuilt 4x3 Pumps – Engineered Strength, U.S. Manufacturing

Alongside our OEM offerings, UnitedBuilt designs and manufactures its own 4x3 centrifugal water truck pumps, engineered for rugged job site performance and built for direct interchange with Berkeley B68416, B68417, B66895, and B66899 models.

Each pump is manufactured using domestic and globally sourced materials, with all CNC-machining, painting, assembly, and quality control completed in Phoenix, Arizona. This ensures tightly controlled tolerances, precise fit, and reliable uptime in the field.

Key features include:

  • Certified StressProof® steel shafts with single-workholding machining

  • 3A aircraft-grade shaft threads

  • Dynamic two-plane impeller balancing for vibration control

  • SAE 3000 gray iron castings produced from virgin iron ore

  • Four ¼-inch NPT drain ports for universal winterization

  • Mechanical seal and rope packing seal compatibility

Every unit is assembled and inspected by experienced machinists who understand the demands of water truck operations—and who take pride in delivering consistent, fleet-ready performance.
