Question by: Connie G on Jul 18, 2025, 6:18 PM
flow rate on this one says 148 liters a minute, that accurate for the 2520VQ series or is that pulled from a different model?
Answer by: Customer Support on Jul 20, 2025, 8:04 AM
That figure is correct for the 2520VQ21A8 11DC20 specifically. At 148.69 liters per minute, it sits in the higher-output range for vane pumps in this series, which is part of why it gets used in press machines and die casting setups where you need consistent volume at speed. Not all VQ series pumps share the same flow rating, so it's worth confirming the model number matches your system requirements before ordering.
