Crane Hydraulic Gear Pump | CBKP-63, CB-KPR-80/80/40, CBKP80/63/32 | Double & Triple Pump

CBKP/CB-KPR Series High-Performance Multi-Stage Crane Hydraulic Gear Pumps

Product Overview: The CBKP/CB-KPR Series is the definitive power heart engineered for cranes and heavy-duty mobile machinery. This range covers everything from high-displacement single pumps like CBKP-63 BFPR to precision triple pumps such as CB-KPR-80/80/40-B1F1J1 and CBKP80/63/32-BF. The core advantage lies in driving multiple gear sets via a single shaft, providing independent and stable high-pressure flow for a crane’s hoisting, slewing, luffing, and outrigger systems. Built with reinforced split-body housing, it is designed to withstand the frequent instantaneous high-pressure shocks typical of crane operations.

Key Technical Advantages:

• Multi-Circuit Independent Output: Unique double (e.g., CBKP80/80-BFP) and triple structures allow a single power source to drive 2-3 independent circuits, simplifying system layout and reducing overall energy loss.

• High-Pressure & Impact Resilience: Constructed with high-strength precision-ground materials, rated for continuous pressures up to 25 MPa (250 Bar). It maintains stable output during initial heavy lifting surges or rapid lowering impacts.

• 100% Direct Replacement: Strictly manufactured to match mounting standards for XCMG, SANY, ZOOMLION, and other mainstream crane brands. Suffixes like BFPR or B1F1J1 ensure that flange spacing, drive shafts (Spline/Keyed), and port configurations are fully compatible.

• Efficient Axial Pressure Compensation: Features pressure-balanced floating side plates, maintaining volumetric efficiency above 93% even in harsh environments, effectively minimizing system overheating.

• Target Applications: Main pumps for truck cranes, lorry-mounted cranes, crawler cranes, mini-cranes (CBKa-G425-At0), and heavy-duty drilling rigs.
