A4VTG90 New Version Charge Pump

Based on comprehensive technical documentation and supplier specifications, the A4VTG90 New Version charge pump is engineered for high-pressure hydraulic applications, featuring advancements in pressure management, operational flexibility, and structural robustness. Below is a detailed technical overview:

1. Core Technical Parameters

【表格】

Specification Details

Displacement 90 cm³/rev (main pump), 25.7 cm³/rev (integrated boost pump)

Pressure Rating Nominal: 400 bar (5,800 psi)Peak: 450 bar (6,500 psi)

Control Modes Dual-mode operation (HW hydraulic servo / EP electric proportional)

Response Frequency Up to 80 Hz (EP mode)

Rotation Speed Max. continuous: 3,050 rpmLimited max.: 3,300 rpm

Fluid Compatibility Mineral oil, HF hydraulic fluids (special variants support HFC oils)

2. Design Enhancements

• Swashplate Reinforcement

Forged steel swashplate with HV1000 surface hardening, reducing deflection by 40% under load versus prior models.

• Integrated Boost System

Built-in gear-type boost pump (25.7 cm³/rev) with adjustable relief valve (280 bar max), eliminating external pre-charge circuits.

• Dual-Mode Controller

• HW Mode:Hydraulic servo with mechanical feedback, optimized for harsh environmental conditions.

• EP Mode:Electric proportional control with manual override, facilitating IoT integration.

• Modular Flange Interface

Configurable SAE-B/C flange options, compatible with A4VG series main pumps in closed-circuit configurations.

3. Material & Durability

• Housing Construction

High-strength cast iron (optional aluminum alloy housing available for 15% weight reduction).

• Sealing System

Dual-lip PTFE oil seals with Viton® backup rings, rated for 450°C flash points.

• Bearing Configuration

Tapered roller bearings with L10 lifespan exceeding 10,000 hours at rated load.

• RFID Maintenance Tag

Embedded NFC chip logging installation dates, maintenance history, and diagnostic codes.

• Condition Monitoring Port

Optional analog/CANbus output for real-time pressure and temperature monitoring.

5. Typical Applications

• Concrete Machinery

Drum drive systems (e.g., PMH P110 mixers) in closed-loop circuits with A4VG main pumps.

• Mining Equipment

Hydrostatic drives for tracked vehicles, operational in -40°C to 100°C temperature ranges.

• Marine Steering Systems

Redundant pump setups with load-sensing control logic.

6. Compliance & Certifications

• Safety Compliance:ATEX Zone 2 certification, GS explosion-proof approval.

• Quality Standards:ISO 9001:2015, IATF 16949 (automotive-grade subcomponents).

• Environmental:ISO 14064 carbon footprint tracking throughout manufacturing.
