DC 3V–3.7V 310 Foam Motor Pump for Soap Dispenser | 0.43A

Q: What power supply does the 310 Foam Motor Pump require?

This foam motor pump operates on DC 3V to 3.7V with a working current of 0.43A–0.46A. It is compatible with standard AA battery packs, small Li-ion cells, or regulated DC power supplies within that voltage range — no mains power required.

Q: What is the difference between this and a regular water pump?

Unlike a standard liquid pump, the 310 Foam Motor Pump includes a dedicated air intake port in addition to the liquid inlet and outlet. This allows it to mix air into liquid as it pumps, producing rich, consistent foam — making it ideal for soap dispensers and foaming beauty devices.

Q: Can I use this pump to replace the motor in my existing foam soap dispenser?

Yes! The 310E foam pump is a widely used replacement motor for foam soap dispensers and hand sanitizer units. Just ensure your dispenser's power supply matches the DC 3V–3.7V operating range and that the inlet/outlet tubing fits the pump connections.

Q: How noisy is this pump during operation?

The pump operates at under 65 dB, which is comparable to a normal conversation. It is quiet enough for countertop bathroom dispensers, bedroom beauty devices, or other settings where low noise is preferred.
