Micro 370 DC Diaphragm Water Pump, A/B Versions

Build a small water-moving function into a compatible project with a miniature 370 diaphragm pump. Separate A and B versions let you choose the electrical range for the supply you plan to use.

• ✅ Use a compact pump body - the roughly 60 mm format suits a small assembly.
• ✅ Match the supply version - A and B have different operating ranges.
• ✅ Connect matching small tubing - the listed inlet and outlet dimensions help assess the fit.

Choose the Voltage Version Before Connection

Type A is described for 3-5 V DC and Type B for 6-9 V DC. Confirm the actual unit markings and current demand, then select an appropriate protected supply and tubing.

Flow depends on voltage, lift and restrictions. No food-contact, drinking-water or continuous-duty approval is established. The pump is a component, not a complete dispenser; supply, tubing and container are not included.
