Product Description
Rexroth A7VKG Series High-Pressure Axial Piston Variable Metering Pump
Product Overview: The Rexroth A7VKG series (including A7VK and A7VKO variants) is a bent-axis axial piston variable pump specifically engineered for polyurethane foaming machines and high-precision chemical metering systems. Renowned for its exceptional volumetric efficiency and high repeatability, the A7VKG series is a cornerstone component in chemical processing, automotive interiors, and insulation material production lines. Core models such as the A7VKG012 and A7VKG028 offer unparalleled stability and wear resistance when handling high-pressure and high-viscosity media.
Key Technical Advantages:
Ultra-High Metering Precision: Utilizing a precision bent-axis design, models like the A7VKG012MA/10MLSK4P350-0 support manual or automatic variable adjustment to ensure minimal fluid ratio errors—essential for producing high-quality foam materials.
Heavy-Duty High-Pressure Design: Optimized for operating pressures up to 350 Bar. Reinforced piston groups and port plates handle high-frequency duty cycles with ease, significantly reducing system downtime for maintenance.
Optimized Sealing & Material Compatibility: The A7VKG series is equipped with specialized MLSK sealing systems and corrosion-resistant materials, ensuring long-term stable operation with chemical media such as Isocyanate (ISO) and Polyol (POL).
Compact Integrated Design: Despite reaching displacements of up to 107cc, its compact footprint allows for easy integration into space-constrained metering stations or foaming machine frames.
Specific Models & Technical Parameters: This product line features core configurations: A7VKG012MA/10MLSK4P350-0, A7VKG012, A7VKG028, A7VKG055, and the full A7VKG107 series.
Displacement Range: 12 cm³/rev to 107 cm³/rev.
Rated Operating Pressure: 350 Bar (35 MPa); Peak pressure up to 400 Bar.
Control Method: Manual adjustment (MA) or other proportional controls.
Applicable Media: Polyurethane raw materials and other industrial chemical fluids.
