HCHC CBKP Series High Pressure Tandem Gear Pump | CBKP100/50/40, CBKP80/63/32 | Crane Hydraulic Pump

HCHC CBKP Series High-Pressure Tandem Hydraulic Gear Pumps for Cranes

Product Overview: The HCHC CBKP Series represents the pinnacle of hydraulic power engineering for Cranes and heavy-duty construction machinery. Featuring high-tensile cast iron bodies, these pumps offer exceptional fatigue resistance and are engineered to withstand the transient pressure spikes common in crane operations. This range features high-performance configurations including double pumps CBKP80/80-BFP, CBKP60/33/25, and powerful triple pump models CBKP80/63/32-BF and CBKP100/50/40-BFP. By enabling dual or triple independent flow outputs from a single drive shaft, they perfectly match the multi-circuit power requirements of hoisting, slewing, and outrigger systems.

Key Technical Advantages:

• Efficient Multi-Circuit Integration: Supports double, triple, or multi-stage configurations (e.g., 100cc + 50cc + 40cc), significantly simplifying hydraulic plumbing and optimizing installation space.

• Reinforced Cast Iron Construction: Utilizing premium ductile iron, the CBKP series offers higher pressure limits (rated at 25 MPa) and superior thermal stability compared to aluminum pumps, preventing housing distortion under heavy loads.

• Superior Shock Resilience: Optimized for the frequent start-stop cycles of truck-mounted and mobile cranes. Equipped with heavy-duty roller bearings to ensure extended service life in harsh outdoor environments.

• High-Precision Axial Compensation: Features a precise pressure-balanced compensation structure that maintains a volumetric efficiency above 93% across the entire operating range.

• Target Applications: Truck-mounted cranes, mobile cranes, crawler cranes, specialized vehicles, and heavy construction hydraulic systems.
