Frequently Asked Questions
What is the maximum operating pressure for A2VK series pumps?
The nominal operating pressure is 250 bar, with a maximum pressure rating of 315 bar for intermittent operation. Some models can handle up to 400 bar in specific configurations.
Are these pumps suitable for polyurethane component metering?
Yes, the A2VK series is specifically designed for pumping and metering polyurethane components (polyol and isocyanate) with high accuracy and material compatibility. The pump components are compatible with the pumped media due to special pairings of materials and sealing elements.
What does the SO2 designation mean in the model number?
SO2 indies special corrosion protection, making the pump suitable for harsh environments and aggressive media. This designation ensures enhanced durability and extended service life in challenging operating conditions.
What is the typical delivery time for these pumps?
Standard delivery time is typically 3-10 days for in-stock items, with custom configurations requiring additional lead time. Production lead time may vary based on order quantity and specific model requirements.
What maintenance is required for long-term operation?
Regular maintenance includes checking oil quality, monitoring for leaks, inspecting shaft seals, and replacing filters as recommended. The pumps are designed for minimal maintenance with proper installation and operation. The modular design facilitates easy component replacement, and the double shaft seals with buffer fluid ports ensure safe operation and environmental protection.
