Plunger Pump A22V Series A22VG045HT1005M1/40BRNB2S73FB2S4A-Y

The quality Plunger Pump A22V Series A22VG045HT1005M1/40BRNB2S73FB2S4A-Y is engineered by Hengmeisi – a leading China manufacturer and factory direct supplier – to replace traditional vane and gear pumps with swashplate variable technology. Rated at 350 bar continuous, 400 bar peak, this model delivers higher volumetric efficiency (96%), lower pulsation (≤1.5%), and smart displacement control for high-end hydraulic applications.

Product Advantages

Swashplate Variable vs. Vane & Gear Pump Designs

Unlike twin-vane, pressure-limiting vane, or internal/external gear pumps, the Plunger Pump A22V Series A22VG045HT1005M1/40BRNB2S73FB2S4A-Y uses a reciprocating plunger in a high-precision cylinder. This eliminates vane-stator friction and gear meshing losses, enabling far higher pressure capacity and efficiency.

Integrated Electro-Hydraulic Proportional Control

The built-in closed-loop variable mechanism receives electric signals to adjust swashplate angle steplessly from 0 to 45 cm³/rev. Displacement deviation is automatically compensated, ensuring stable output – a leap beyond manual or pressure-limited adjustments.

Premium Materials for Extreme Durability

Cylinder & plunger: 40CrNiMoA alloy steel, carburized, quenched, and precision-ground to HRC65 hardness.

Swashplate: Wear-resistant coating + precision grinding reduces friction loss.

Seals: Imported PTFE composite, rated -30°C to +120°C, leak-free at 400 bar.

Bearings: High-precision tapered roller bearings handle radial & axial loads at 3000 r/min, 16,000-hour service life.

Built-in Contamination Control

An integrated anti-pollution filter protects plungers and variable mechanisms from hydraulic oil impurities – critical for long-term reliability in harsh environments.

Model Code

The model code A22VG045HT1005M1/40BRNB2S73FB2S4A-Y has a clear and intuitive coding logic, which is easy for purchasers to quickly identify product parameters and configuration without professional hydraulic knowledge, and is completely different from the model interpretation of previous series:

A22V = Swashplate variable plunger pump series (core series identifier, distinguishing from vane pump and gear pump series);

G = High-precision variable control mode (electro-hydraulic proportional control, realizing intelligent adjustment of displacement);

045 = Rated displacement of 45 cm³/rev, suitable for medium and large flow high-pressure hydraulic system needs;

HT = High-temperature resistant configuration, adapting to high-temperature working environments up to 120℃;

1005M1 = Standard cylinder body and plunger assembly, ensuring high precision and stability;

40 = Installation flange specification (conforming to ISO 3019/2), compatible with most high-end industrial equipment;

BRNB2S73FB2S4A-Y = Integrated high-pressure sealing + anti-pollution filter configuration, ensuring no oil leakage under high pressure and adapting to complex working environments with impurities.

As the core model of the A22V series, A22VG045HT1005M1/40BRNB2S73FB2S4A-Y is specially optimized for high-pressure, high-precision and high-temperature scenarios, with outstanding comprehensive performance, and is widely favored by global purchasers in high-end engineering, metallurgy and aerospace supporting fields.
