ALU Gear Pumps -General Purpose Aluminum Gear Pumps For Open Loop Circuits

ALU Gear Pumps are general-purpose aluminum gear pumps designed for use in open-loop hydraulic circuits. These pumps are commonly utilized in various industries for fluid power applications where durability, reliability, and cost-effectiveness are important.

1. Construction and Design

Material: The primary housing is made of aluminum alloy, providing a balance between lightweight construction and sufficient strength.
Gears: High-strength steel or bronze gears are typically used for longevity and efficient fluid movement.
Shaft and Bearings: The drive shaft is supported by bearings designed for high radial and axial loads.

2. How It Works

Positive Displacement Pump: Gear pumps operate by trapping hydraulic fluid between the gears and the pump casing, transferring it from the inlet to the outlet under pressure.
Open Loop Circuit: The pump draws fluid from a reservoir and delivers it to the hydraulic system before returning it to the reservoir.

3. Key Features

Compact and Lightweight Design: Aluminum construction reduces weight, making it ideal for mobile machinery.
High Efficiency: Precision-machined components minimize internal leakage and maximize volumetric efficiency.
Corrosion Resistance: Aluminum housing offers good resistance to corrosion, enhancing pump life.
Versatile Mounting Options: Available with various flange and port configurations to suit different equipment designs.

4. Performance Characteristics

Flow Rates: Capable of delivering a wide range of flow rates depending on the pump size and operating speed.
Pressure Ratings: Typically designed for medium to high-pressure applications up to 250 bar (3,625 psi) or more.
Speed Range: Supports varying input speeds to accommodate different hydraulic power units.

5. Applications

Agriculture: Used in tractors, harvesters, and other farming equipment for hydraulic steering and implements.
Construction: Powers hydraulic systems in excavators, loaders, and other heavy machinery.
Material Handling: Provides hydraulic power for forklifts, lift trucks, and cranes.
Industrial Machinery: Powers hydraulic presses and automation systems.

6. Advantages

Cost-Effective: Aluminum construction is less expensive than cast iron or steel alternatives.
Good Power-to-Weight Ratio: Lightweight yet robust enough for heavy-duty applications.
Easy Maintenance: Simplified design allows for quick service and replacement.
