Product Description
KP30 Series High-Performance Hydraulic Gear Pumps for Mini Excavators
Product Overview: The KP30 Series serves as the vital power core for modern mini excavator hydraulic systems. This featured selection includes precision models optimized for complex digging environments: KP30.31-A8K9-LMD/MB-45 and the specialized configuration KP30.34-05S6-LMF/OD-M5-KSL/30.3. Engineered with high-strength three-piece cast iron construction, these pumps are specifically designed to meet the rigorous demands of mini excavators for high pressure (up to 25 MPa) and precise flow distribution during digging, swing, and travel operations, ensuring exceptional reliability in extreme working conditions.
Key Technical Advantages:
Excavator-Specific Optimization: Displacement-tuned for mini excavator multi-way valve systems, ensuring coordinated and agile movements of the boom, arm, and bucket.
Superior Pressure & Shock Resilience: Rated for a continuous operating pressure of 20.6 MPa with peaks reaching 25 MPa (3625 PSI), built to absorb instantaneous load shocks during heavy digging.
100% Plug-and-Play Replacement: Strictly adheres to original OEM specifications. Suffix codes like A8K9 and 05S6 guarantee that flange pilots, shaft spline tooth counts, and port positions are 100% identical for a seamless installation.
High Volumetric Efficiency: Features automatic axial gap compensation technology to minimize internal leakage, maintaining efficiencies over 93% during continuous long-term operation while controlling system heat.
Low-Noise Operation: Precision-ground gear sets drastically reduce mechanical noise under high-pressure cycles, enhancing operator comfort.
Detailed Models & Parameters:
Core Series: KP30 Heavy Duty Performance Series.
Model Keywords: KP30.31-A8K9-LMD/MB-45, KP30.34-05S6-LMF/OD-M5-KSL/30.3.
Displacements: Covering core specs like 31cc, 34cc/rev.
Pressure Ratings: Rated at 20.6 MPa (210 Bar) continuous; Peak at 25 MPa (250 Bar).
Target Applications: Main pumps for 0.8 ton – 3.5 ton mini excavators, compact skid steer loaders, and municipal construction machinery.
