Applications
Applications
Engine-Driven Steering & Auxiliary Systems: The primary choice for Cummins 6BT / QSB3.9 / QSB5.9 engine applications, including heavy-duty truck power steering and auxiliary hydraulic circuits, where the pump’s high efficiency ensures stable control even at varying engine speeds.
Construction & Utility Vehicles: Widely used in small excavators, backhoe loaders, and utility trucks, powering boom arms, outriggers, and auxiliary functions. Its cast iron construction and pressure-balanced design withstand shock loads and harsh site conditions.
Material Handling Equipment: Ideal for forklifts, truck tail-lifts, and hydraulic ramp systems, offering consistent high-pressure output for lifting and lowering operations while maintaining high efficiency under continuous, heavy-duty cycles.
Agricultural Machinery: Commonly integrated into tractors, harvesters, and fertilizer spreaders, where it powers steering, lift arms, and implement control systems. The pump’s contamination tolerance handles the dirty, high-dust environments common in field operations.
Commercial & Light Industrial Applications: Suitable for small-scale presses, power units, and general-purpose hydraulic systems, providing reliable performance for clamping, pressing, and actuation tasks in workshops and mobile service units.
Factory&FAQ
CB32 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The CB32 is a high-performance, fixed-displacement external gear pump, widely used as a reliable hydraulic power source for Cummins 6BT/QSB series engines and other mobile equipment. Built with a rugged cast iron body and pressure-balanced wear plates, it is engineered for compact hydraulic systems requiring stable high-pressure output and long service life, especially in truck-mounted and construction applications.
Rugged Cast Iron Housing: Unlike aluminum pumps that can deflect or distort under high pressure, the CB32’s cast iron construction maintains tight internal clearances, reducing leakage and extending service life under continuous high-pressure cycles.
Pressure-Balanced Wear Plates: Its advanced axial compensation design automatically adjusts clearances to minimize internal bypass, maintaining high efficiency even as components wear, unlike basic aluminum pumps with fixed clearances.
Proven Compatibility with Diesel Engines: Optimized for direct coupling to diesel engine PTOs and power take-off units, the CB32 is built to handle engine vibration, thermal cycling, and varying speed conditions common in heavy-duty mobile applications.
Continuous Pressure: Up to 2,320 PSI (160 bar).
Intermittent/Peak Pressure: Up to 2,900 PSI (200 bar).
This robust pressure rating makes it ideal for power steering, lifting, and auxiliary hydraulic circuits in trucks and construction machinery.

To ensure a successful swap, verify the Mounting Flange, Shaft Type, and Displacement (cc/rev) to match your existing system.
Oil Type: Premium anti-wear (AW) mineral-based hydraulic fluids, compatible with common diesel engine environments.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 10–100 cSt, suitable for typical mobile equipment working temperatures.
Filtration: Cleanliness is critical for pump life. A minimum filtration level of ISO 4406 18/16/13 is recommended to prevent abrasive contamination from damaging the gears and wear plates.
Rated Speed: 1,500–2,000 RPM
Maximum Continuous Speed: 2,500 RPM
Operating outside this range (too low or too high) can reduce efficiency or shorten service life.
