❓ FAQ – Frequently Asked Questions

Question	Standard Answer
What is the difference between VR and S models?	VR is variable speed model with adjustable flow rate; S is fixed speed model running at maximum flow permanently.
Is the running noise really ≤35dB?	Yes. Its operating sound is quieter than the quiet environment inside a library.
What voltage options are available for this pump?	Three voltage versions for selection: 12V, 24V and 36V DC.
What material is the pump housing made of?	PPS+30%GF reinforced plastic, which resists acid, alkali, oil, saltwater and high temperature corrosion.
Can this pump deliver hot liquid?	The standard pump supports liquid temperature up to 60°C. Custom high-temperature resistant versions are available upon request.
What is the waterproof rating of this circulation pump?	IP68 full waterproof grade; the pump body can work fully submerged in liquid.
Do you provide OEM & ODM customized services?	Yes, we support full OEM & ODM customization. Please contact our sales team for detailed cooperation information.
