Rexroth A2VK High-Pressure Polyurethane Metering Pump

Product Overview: The Rexroth A2VK series is the world’s leading metering solution for High-Pressure Polyurethane (PU) foaming equipment. Specifically engineered to handle high-viscosity and chemically corrosive components such as Isocyanates (ISO) and Polyols (POL), the series—including flagship models A2VK28GEOR1GOPE1-S06 and A2VK12MAOR4GOPE2-S02—utilizes bent-axis variable displacement technology. The S06 and S02 specifications are tailored with specialized sealing and rotating groups to ensure micro-precise component ratios under high-pressure cycles. It is the premier choice for refrigerator insulation, automotive component foaming, and sandwich panel production lines.

Key Technical Advantages:

• Superior Metering Consistency: Precision bent-axis piston technology ensures stable pressure at the mixing head, preventing uneven foam density and reducing scrap rates.

• Specialized Seal Configurations (S06/S02):

  • S06 Specs: Reinforced for Isocyanate (ISO) to prevent damage caused by material crystallization and wear.

  • S02 Specs: Optimized pumping efficiency for Polyols (POL) and premixed polyethers with excellent chemical compatibility.

• Versatile Control Modes:

  • MA (Manual Control): Features a graduated scale for high-precision manual flow adjustments.

  • GEO (Special Control/Proportional): Meets high-end requirements for real-time displacement monitoring and automated adjustments.

• High-Pressure Reliability: Supports continuous operating pressures up to 250 Bar (3625 PSI), maintaining long service intervals even under heavy-duty cycles.

• OEM-Standard Integration: Manufactured to strict standards, ensuring seamless integration with the hydraulic units of major foaming machine brands (e.g., Hennecke, Cannon, KraussMaffei).
