Water Pump Powerheads

UnitedBuilt offers a selection of water truck pump powerheads designed as a cost-effective solution for rebuilding and maintaining centrifugal water truck pumps. A powerhead includes the shaft, bearings, and seal assembly, and is designed to bolt directly to your existing volute, allowing you to restore pump performance without replacing the entire unit.

Our UnitedBuilt powerheads are engineered for durability and reliable operation in demanding applications. Available in both mechanical seal (M3ZRMS) and rope packing seal (M3ZRM) configurations, these units provide flexibility based on your maintenance preferences and operating conditions.

Built for compatibility with Berkeley-style B3ZRM and B3ZRMS pumps, UnitedBuilt powerheads offer a dependable replacement option for worn or damaged pump assemblies. Whether you’re rebuilding a pump in the field or performing routine maintenance, these components help reduce downtime and extend the life of your equipment.

We work to keep these components readily available and offer fast shipping to help keep your operation running efficiently.
