Rexroth A2VK Metering Pump | A2VK12, A2VK28, A2VK55, A2VK107 | Polyurethane Foaming Pump

Rexroth A2VK Series High-Pressure Polyurethane Metering Pump

Product Overview: The Rexroth A2VK series is a high-pressure bent-axis axial piston variable pump specifically engineered for Polyurethane (PU) processing machinery. As the “heart” of foaming systems, it is the global standard for the precise metering of Isocyanate and Polyol. Featuring a robust Bent-Axis architecture and specialized sealing, the A2VK range delivers exceptional repeatability and accuracy under high-pressure cycles, ensuring consistent quality in foam production.

Key Technical Advantages:

• Exceptional Metering Accuracy: Purpose-built for chemical dosing with a high-precision Manual Adjustment (MA) mechanism. Models like the A2VK28 and A2VK55 allow for fine-tuned flow control, maintaining perfect chemical ratios.

• High-Pressure & Heavy-Duty Design: Rated for a continuous operating pressure of 250 Bar (25 MPa). The reinforced drive shaft and bearing systems are optimized to handle viscous chemical media, significantly extending intervals between maintenance.

• Optimized Sealing for PU Media: Utilizing specialized shaft seal technology (SO2 specification), the pump prevents wear from Isocyanate crystallization, ensuring zero-leakage operation in 24/7 continuous production environments.

• Highly Modular Configuration: Available in displacements from A2VK12 to A2VK107. Control codes such as MAOR4G0 and MAOR1G1 represent standardized interfaces for seamless industrial integration.
