Water Truck Pumps

UnitedBuilt offers a complete selection of water truck pumps, including our own line of 4x3 cast iron centrifugal pumps designed for demanding dust suppression and fluid transfer applications. Engineered for durability and performance, our pumps are manufactured in the USA using domestic and global high-quality materials and built to strict quality standards.

Our UnitedBuilt pumps are available in both mechanical seal (M3ZRMS) and rope packing seal (M3ZRM) configurations, providing flexibility based on your maintenance preferences and operating conditions. Each model is designed as a direct replacement for Berkeley-style B3ZRM and B3ZRMS water truck pumps, ensuring easy integration and reliable performance.

In addition to our aftermarket lineup, we also stock and distribute genuine OEM water truck pumps from Berkeley and Franklin Electric, along with a full range of pump repair parts and components.

With a large inventory on hand and fast shipping, UnitedBuilt helps minimize downtime and keep your equipment operating at peak performance. Whether you need a complete pump or replacement parts, you’ll find dependable solutions built for the job.
