The UnitedBuilt B66895MS Water Truck Pump is a heavy-duty, high-quality aftermarket replacement for the Berkeley B66895 (B3ZRM), engineered for reliable performance in demanding water truck and dust suppression applications.
This 4" x 3" centrifugal pump features grooved suction and discharge connections, allowing for quick installation and simplified maintenance. The counter-clockwise (CCW) rotation makes it ideal for specific PTO and hydraulic drive configurations requiring reverse rotation.
Equipped with a packed (rope) seal, this pump offers a field-serviceable sealing solution that allows for easy adjustment and maintenance—ideal for operators who prefer rebuildability over mechanical seal replacement.
Built for durability, the B66895 is constructed from ASTM A126 Class 30B cast gray iron and features a Niagara LaSalle StressProof® shaft (AISI 1144) for superior strength, wear resistance, and long service life.
With performance ratings of up to 750 GPM at 65 PSI @ 2500 RPM, this pump delivers consistent output for water trucks, construction equipment, and industrial applications.
Proudly manufactured in the USA with domestic and imported materials, the UnitedBuilt B66895MS provides a rugged, cost-effective alternative to OEM pumps.
