Key Features
High Metering Accuracy
The A2VK series delivers exceptional metering precision with reproducible variable flow volumes, ensuring consistent performance in polyurethane component applications. The pumps feature high volumetric efficiency for superior metering accuracy.
Robust Construction
Featuring a swash plate design with specially matched materials and sealing elements, these pumps are compatible with polyol and isocyanate media, providing long service life and minimal maintenance requirements. The double shaft seals with buffer fluid ports guarantee safe operation and environmental protection.
Low Pulsation Operation
Advanced design minimizes flow pulsation, even when pumping highly viscous fluids, resulting in smooth operation and reduced system stress. This low pulsation characteristic ensures stable performance in demanding applications.
Quiet Performance
Engineered for low-noise operation, making these pumps suitable for noise-sensitive environments and applications requiring minimal acoustic impact. The compact design and optimized internal components contribute to reduced vibration and noise levels.
Corrosion Protection
SO2 protection ensures reliable operation in harsh environments and with aggressive media, extending pump life and reducing maintenance costs. The corrosion-resistant materials and coatings provide enhanced durability in challenging operating conditions.
