Pump only; select the drive and installation components separately.
The Berkeley B62323 B4JRMBH is a frame-mounted centrifugal water pump with 5-inch suction x 4-inch discharge flanged connections. This exact configuration uses counterclockwise rotation, a cast iron impeller and a packing seal.
Use it for a water-truck replacement or build where the pump configuration, plumbing and separate drive match the application. The B4JRMBH family name by itself is not enough to identify the right pump: verify the complete B62323 part number, rotation and seal arrangement against the existing equipment or project requirements.
The packing seal uses an adjustable gland. Controlled leakage is necessary to lubricate and cool the packing, so this configuration should not be selected with the expectation of a completely dry stuffing box.
Match the pump and drive to the water system
The frame-mount arrangement allows the pump to work with a suitable separate power source through an appropriately selected coupling or belt drive. It gives the installer a way to match the pump drive to the available power source instead of assuming a motor or engine is supplied with the pump. The packing arrangement can be adjusted and serviced as part of routine pump maintenance. Keep the gland accessible in the installation and follow the manufacturer’s startup and leakage-adjustment procedure. Select the drive using the required water flow, total dynamic head and the exact pump performance curve. A larger engine, higher shaft speed or different impeller trim changes the operating conditions; none should be treated as an automatic improvement or a substitute for checking the duty point.

Compatibility and components
| Component or application |
Selection guidance |
| Pump assembly |
The specified B62323 pump; not a motor-driven package. |
| Motor or engine |
Select separately for the required duty point and available power. |
| Coupling or belt drive |
Select separately and align to the pump and power-source shafts. |
| Companion flanges and piping |
Confirm flange pattern, gasket selection and any required flange kits. |
| Guards and mounting |
Provide suitable support and guarding for the selected drive. |
Before ordering
| Check |
What to confirm |
| Exact configuration |
Confirm B62323, B4JRMBH, CCW rotation and the required seal type. |
| Flow and pressure |
Supply the required flow and total dynamic head; check the exact performance curve, shaft speed and power demand. |
| Suction conditions |
Confirm sufficient inlet supply and available NPSH for the installation; prime the pump before starting. |
| Drive and piping alignment |
Support piping independently and align the drive; do not force piping into place at the flanges. |
| Safe operation |
Keep rotating-drive guards in place, disconnect power before service and never run the pump dry. |
| Seal maintenance |
Allow controlled packing leakage and maintain access to the gland for adjustment. |
