Product Description
CBT-E3 Series High-Performance High-Pressure Hydraulic Gear Pumps
Product Overview: The CBT-E3 Series (often interchangeable with the CBN series) is one of the most reliable and widely used power sources in modern hydraulic systems. As a high-performance external gear pump, the CBT-E3 series features a high-tensile extruded aluminum alloy body, specifically engineered to handle pressure spikes and rigorous operation. This featured range covers the entire spectrum from the micro-displacement CBT-E304 to the high-flow CBT-E325, including popular models like E306, E310, and E316. Equipped with advanced axial gap compensation, these pumps deliver exceptional volumetric efficiency even under fluctuating loads.
Key Technical Advantages:
Lightweight High-Strength Design: The pump body is crafted from specialized extruded aluminum with precision cast covers, maintaining structural integrity under continuous high-pressure (Rated 16-20 MPa).
100% Direct OEM Replacement: Manufactured strictly to international mounting standards. Whether it’s flange connections, shaft types (Keyed/Splined), or porting, these pumps provide a seamless fit for major global brands.
Superior Volumetric Efficiency: Equipped with pressure-balanced floating side plates that adjust clearances automatically, maintaining efficiency above 93% and reducing system heat generation.
Smooth & Quiet Operation: Optimized gear profiles combined with heavy-duty self-lubricating bearings significantly reduce mechanical vibration and hydraulic noise.
Target Applications: Main pumps for 1-3.5T forklifts, harvester steering circuits, tractor hydraulic lifts, sanitation trucks, and various industrial hydraulic power units.
