Important Notes

⚠️ Information including continuous working time, working temperature and medium is required to be pre-confirmed with professionals; pump cannot work with high temperature or corrosive fluids.

⚠️ When pump is connected into circulation system, load current will be reduced to 70~85% of Max working current (opening outlet current).

⚠️ The head means the Max vertical lifting height of water, the flow is 0L/MIN@max head.

⚠️ The max flow rate means flow rate with no lifting height (according to the curve below).

❓ FAQ – Frequently Asked Questions

Question	Answer
Is this pump really quiet?	Yes! With three-phase sine wave control, noise is <40dB – quieter than a refrigerator. Perfect for bedrooms and quiet environments.
Can I use it for saltwater?	Yes, the pump is compatible with saltwater. For prolonged marine use, we recommend the PPS housing option for maximum corrosion resistance.
What liquids can it handle?	Water, oil, mild acids, and alkalis. For special liquids, please pre-test or consult our technical team.
Can I adjust the speed?	Yes! The pump supports PWM speed control, 0-5V analog signal, or potentiometer adjustment. We can customize it to your needs.
Is it submersible?	Yes, IP68 rated – fully submersible. You can also use it in-line (non-self-priming).
What's the difference between DC40F-1240 and DC40F-2460?	DC40F-1240 is 12V with 4.0M head and 780L/H flow. DC40F-2460 is 24V with 6.0M head and 960L/H flow.
