CBK Series High-Performance Micro Power Unit Gear Pumps

Product Overview: The CBK Series is a high-pressure power core specifically engineered for compact hydraulic systems. As a premier external gear pump, this series is the industry standard for AC/DC micro-hydraulic power units due to its ultra-compact footprint and superior pressure-balancing capabilities. This featured range includes core models: CBK1012-B21R, CBK1008-B3F, CBK1016-B1FR, and the high-displacement CBK1025. Featuring high-strength aluminum alloy bodies and axial gap compensation, these pumps deliver exceptional efficiency even under frequent start-stop cycles.

Key Technical Advantages:

• Ultra-Compact Design: Optimized for the limited internal space of power packs, allowing direct integration into manifold blocks.

• High Pressure Resilience: Rated for a continuous working pressure of 20 MPa (200 Bar) with peak pressures reaching 25 MPa, ideal for heavy-duty lifting applications.

• Flexible Configurations: Suffixes like B21R and B3F define various shaft types (Keyed, Splined, or Tang shaft) and rotation directions to match global motor specifications.

• Superior Volumetric Efficiency: Equipped with automated axial pressure compensation, maintaining efficiency above 93% throughout its service life, effectively minimizing system heat generation.

• Target Applications: Truck tail lifts, electric forklift steering, hydraulic lifting platforms, micro-sweepers, and various mini-hydraulic power units.
