Product Description
KP05 Series High-Performance Hydraulic Gear Pumps for Forklift Steering
Product Overview: The KP05 Series is a high-precision power component specifically engineered for compact industrial hydraulic systems. As the industry standard for forklift steering pumps, this series includes a range of core models: KP0540AHSS, KP0560AHSS, KP0588CPSS, KP0553CTSS, and KP0570CTSS. Featuring a high-strength, lightweight aluminum alloy body and advanced floating bush technology, these pumps ensure superior volumetric efficiency and ultra-low noise levels even under 21 MPa continuous high-pressure conditions.
Key Technical Advantages:
100% Plug-and-Play Replacement: Strictly designed to match original Shimadzu OEM parameters. Suffixes such as AHSS (Standard), CPSS (Reinforced Seal), and CTSS (Special Ports) guarantee a seamless fit with your original equipment.
Advanced Pressure Compensation: Equipped with automated axial gap compensation to minimize internal leakage, maintaining a volumetric efficiency over 93%, which effectively reduces hydraulic system heat generation.
Heavy-Duty Pressure Resilience: Rated for a continuous operating pressure of 21 MPa (210 Bar) with peaks up to 25 MPa, built to absorb hydraulic shocks and extend the service life of downstream steering valves.
Quiet & Smooth Operation: Optimized for frequent forklift steering cycles, the low-pulsation gear design reduces cabin decibels and provides a stable, responsive steering feel.
Target Applications: Primarily used as main steering pumps for 1-3.5 ton forklifts (Toyota, Nichiyu, Komatsu, etc.), as well as tail lifts and micro Hydraulic Power Units (HPU).
