Product Description Product DescriptionThe EX135 Gear Pump is a compact, high-performance external gear pump engineered to deliver steady, energy-efficient hydraulic power across a wide range of industrial and mobile machinery. Designed for simplicity, durability, and ease of integration, this pump excels in transferring hydraulic oil at moderate pressures while maintaining consistent flow rates-even in demanding operating conditions.Ideal for OEMs, system integrators, and maintenance teams, the EX135 balances cost-effectiveness with robust engineering, making it a go-to choice for systems requiring reliable performance without compromising on efficiency. Features1. Precision Gear EngineeringOptimized Helical Gear Design: Features precision-ground helical gears with involute tooth profiles, reducing noise (≤72 dB(A) at rated speed) and minimizing flow pulsation for smoother actuator operation.High-Strength Alloy Steel Construction: Gears and shafts are crafted from 20CrMnTi alloy steel, case-hardened to HRC 55+ (surface hardness), balancing wear resistance with toughness to extend service life by 25% vs. standard mild steel pumps.2. Compact & Lightweight BuildAluminum Alloy Housing: A rigid, corrosion-resistant aluminum alloy chassis reduces weight to just 5.9 kg while maintaining dimensional stability under pressure (max working pressure: 200 bar).Sleek, Space-Saving Profile: Compact dimensions (L×W×H: 180mm×120mm×105mm) simplify installation in tight spaces, such as mobile machinery cabs or industrial equipment enclosures.3. Efficient Fluid DynamicsLow-Friction Internal Geometry: Streamlined porting and precision-machined clearances maximize volumetric efficiency (up to 88% at 1800 rpm), reducing energy waste and heat generation.Thermal Balance Design: Ventilated housing and optimized oil flow paths dissipate heat effectively, ensuring stable performance in ambient temperatures ranging from -20°C to +100°C.4. Leak-Free Sealing SystemDual-Lip Nitrile Seals: Prevents oil leakage and contamination ingress, even during pressure spikes or vibration (IP54 protection rating), ensuring long-term reliability in dusty or wet environments.Technical SpecificationsParameterValueModel NumberEX135Displacement (cm3/rev)135Max Working Pressure (bar)200Rated Speed (rpm)1200-1800Max Speed (rpm)2000Volumetric Efficiency (%)≥88 (at 1500 rpm, 120 bar)Port Size (ISO 228/1)1" BSPP (Inlet/Outlet)Operating Temperature (°C)-20 to +100Weight (kg)5.9Material (Gear/Shaft)20CrMnTi (case-hardened)Sealing MaterialNBR (optional FKM)ApplicationsThe EX135's versatility makes it suitable for diverse hydraulic systems, including:Mobile Machinery: Small excavators, skid-steer loaders, and utility vehicles (e.g., cement mixers, street sweepers).Industrial Equipment: Hydraulic presses, material handling conveyors, and small injection molding machines.Agricultural Machinery: Tractor implements (e.g., loaders, balers) and irrigation system pumps.Marine & Offshore: Auxiliary hydraulic units for small boats (e.g., winches, deck cranes) and offshore platform maintenance tools.
