Gear oil pump AZPF Series AZPU-22-022RDC07KB

⚙️ Product Description

Direct replacement for Rexroth's equivalent models. Gear oil pump AZPF Series AZPU-22-022RDC07KB gear pump – precision‑machined, optimized gears, smooth flow, low pulsation. Supports long runs, resists contaminants, lasts long. Widely used in standard hydraulics.

✨ Product Advantages

🔹 Optimized Gear Pump Structure

Different from plunger pumps and vane pumps, AZPU-22-022RDC07KB has a simple and compact structure. It has fewer vulnerable parts, low failure rate and easy daily maintenance, greatly reducing later use cost for users.

🔹 Stable Pressure & Low Vibration

Precision ground gear pairs ensure tight meshing. The pump outputs steady flow and pressure, effectively lowering pressure ripple and vibration. It works well in scenarios requiring smooth hydraulic transmission.

🔹 High Strength & Wear Resistance

The pump body uses high-quality aluminum alloy for light weight and rigidity. Gears and bearings are made of hardened alloy steel, which resists abrasion even under long-term high-load working conditions.

🔹 Excellent Sealing Performance

Adopting premium oil seals, the pump adapts to wide temperature range. It maintains zero leakage under rated pressure, prevents oil contamination and guarantees stable operation of the whole hydraulic system.

🏗️ Product Structure

🧩 Overall Structure: Integrated Gear Pump Assembly

AZPU-22-022RDC07KB is composed of driving gear, driven gear, sliding bearings, aluminum housing, sealing components and mounting flange, with neat layout and small installation space.

⚙️ Working Principle

When the gears rotate, hydraulic oil is sucked in from the inlet and discharged under pressure at the outlet. It converts mechanical energy into hydraulic energy to provide power for the supporting equipment.

🛡️ Core Material Configuration

All key moving parts are processed with strict precision. The matched materials greatly improve wear resistance, pressure resistance and service life of the whole pump.

🛡️ Built-in Protection Design

Reasonable internal oil channel design avoids hydraulic impact. It can effectively protect internal components and adapt to complex and harsh working environments.
