Gear oil pump AZPF Series AZPF-12-011LCB20MB

📋 Product Description

Hengmeisi provides reliable products that meet Rexroth standards. The quality Gear oil pump AZPF Series AZPF-12-011LCB20MB gear pump is engineered by Hengmeisi – a leading China manufacturer and factory direct supplier. Built for compact industrial systems, it delivers stable flow, high wear resistance, and reliable performance in various hydraulic applications.

✅ Product Advantages

▼ Gear Pump vs. Other Hydraulic Pump Designs

Unlike vane pumps or plunger pumps, the AZPF-12-011LCB20MB external gear pump uses precision-machined gear wheels with 12 teeth, minimizing flow pulsation and noise. This eliminates complex variable mechanisms, ensuring simple structure, low maintenance, and consistent performance.

▼ High-Pressure Slide Bearing System

Equipped with heavy-duty slide bearings, the AZPF-12-011LCB20MB absorbs high bearing forces, supporting continuous pressure up to 250 bar (peak 280 bar). The bearings offer excellent dry-running qualities, especially at low rotational speeds, extending service life.

▼ Premium Materials for Durability

☀ Housing: High-strength aluminum alloy, lightweight yet robust

☀ Gears: Precision ground alloy steel, wear-resistant

☀Seals: High-quality components compatible with -30°C to +120°C operating temperatures, leak-free at full pressure

Low Pulsation & Quiet Operation

The 12-tooth gear design of AZPF-12-011LCB20MB reduces pressure ripples, resulting in smoother flow and quieter operation compared to standard gear pumps. This makes it ideal for applications sensitive to vibration and noise.

🔢 Model Code Explanation

The model code AZPF-12-011LCB20MB follows a clear, intuitive logic for easy identification:

★ AZPF: External gear pump series (distinguished from vane/plunger pump series)

★ 12: Series designation, indicating size and configuration

★ 011: Rated displacement of 11 cm³/rev, suitable for medium-flow hydraulic systems

★ L: Rotation direction and port configuration

★ C: Seal material and temperature rating

★ B: Shaft design (flat key)

★ 20: Pressure rating and bearing type

★ M: Mounting flange specification, compatible with standard industrial equipment

The AZPF-12-011LCB20MB is optimized for compact, high-efficiency scenarios, making it widely favored by global purchasers in industrial machinery, material handling, and mobile hydraulics.

🏗️ Product Structure

1. Core Architecture: External Gear Pump StructureFundamentally different from vane pumps or plunger pumps, the AZPF-12-011LCB20MB consists of high-precision gear wheels, slide bearings, aluminum housing, and integrated seals.

2. Working Principle: Meshing Gear TechnologyAs gears rotate, they create suction at the inlet, drawing hydraulic fluid into the pump. The fluid is then carried between the gear teeth to the outlet, where the meshing of gears forces the fluid out at high pressure.

3.Material Upgrades

● Gears: Alloy steel with precision grinding for low wear

● Housing: Lightweight, corrosion-resistant aluminum alloy

● Seals: High-performance components for leak-free operation at high pressures

4. Integrated Reliability Features

Built-in pressure relief options and robust bearing design prevent premature wear, ensuring long-term reliability in industrial environments.
