Gear oil pump AZPF Series AZPFF-10-011/005RSA2020MB

⚙️ Product Description 

The premium Gear oil pump AZPF Series AZPFF-10-011/005RSA2020MB tandem gear pump is engineered by Hengmeisi – a leading China manufacturer and factory direct supplier. This dual-section pump features two integrated gear stages (11 + 5 cm³/rev), delivers reliable flow distribution, and ensures consistent performance in space-limited hydraulic applications。

✨ Product Advantages

🔹 Tandem Dual Gear Pump Structure Design

Unlike single gear pumps or plunger pumps, the AZPFF-10-011/005RSA2020MB combines two independent gear stages in one compact housing. It eliminates the need for multiple separate pumps, saving installation space while providing simultaneous flow to two different hydraulic circuits.

🔹 High-Precision Gear Meshing for Low Noise

Precision-machined gear pairs reduce flow pulsation and vibration, resulting in quiet operation. The optimized tooth profile minimizes pressure ripples, making it suitable for noise-sensitive industrial environments and mobile machinery.

🔹 Premium Materials for Durability

★ Housing: High-strength lightweight aluminum alloy, corrosion-resistant

★ Gears: Hardened alloy steel with precision grinding for wear resistance

★ Seals: High-performance materials compatible with -30°C to +120°C, leak-free at full pressure

🔹 Integrated Pressure & Flow Stability

Each pump stage operates independently, maintaining stable flow even under varying load conditions. The integrated design ensures synchronized performance, reducing system complexity and improving overall reliability.
