When every second counts on the job site, having access to high-quality, in-stock parts can make the difference between productivity and downtime. At UnitedBuilt, we proudly stock and distribute a wide range of OEM water truck pumps from trusted manufacturers like Berkeley and Franklin, as well as our own precision-engineered 4x3 centrifugal pumps—manufactured with rigorous quality standards and fast availability.
Whether you're replacing a worn-out pump, upgrading your fleet, or need fast repair parts, UnitedBuilt gives you access to reliable, high-performance solutions backed by knowledgeable support and outstanding value.
UnitedBuilt is your direct source for OEM water pumps manufactured by Berkeley and Franklin—two of the most respected names in the water pump industry. These pumps are built for heavy-duty performance, making them ideal for construction, dust control, mining, and agricultural applications.
We carry a full range of pump sizes and configurations, including:
4x3 and 5x4 centrifugal water pumps
Self-priming water pumps
PTO driveshaft and hydraulic-driven pumps
Mechanical seal and rope packing seal pumps
Reseal and shaft kits
Impellers, casings, and wear rings
Each part is engineered to fit, built to last, and designed specifically for water trucks.
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

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.
