Choosing your pump and solenoid valve
Three questions are usually enough: what voltage, what flow rate, and whether the liquid needs to be pulled in or simply pushed. The models in this category run on low DC voltage (3-6 V, 12 V, 24 V), which makes them easy to control from a development board with a transistor or a relay module.
- Flow rate and head: a Mini Pompe a eau 3-6V 120L/H suits a small cooling loop or a fountain; the pompe à eau brushless 12vdc 240l/h offers a 3 m delivery head and quiet operation, useful for an aquarium.
- Self-priming or not: a diaphragm pump such as the R385 6-12 V can draw in liquid, whereas a submersible pump must stay immersed so it does not run dry.
- Solenoid valves: they open or close the flow path. Check the coil voltage (12 V or 24 V as on the CWS1), the fitting diameter and the minimum opening pressure, given in PSI on some Deltrol models.
- Measurement and safety: a YF-B5 flow sensor in 3/4" counts the liters passing through, while a level float prevents overflow or dry running.

Frequently asked questions
What is the difference between a submersible pump and a diaphragm pump?
A submersible pump works while immersed in the liquid and cannot draw from a distance; a diaphragm pump, such as the R385, is installed outside the water and creates suction, so it can pull liquid up from a lower tank.
Can I connect a 12V pump directly to an Arduino?
No, a board's pins cannot supply the current needed. Power the pump from a separate 12 V source and switch it with a relay or a MOSFET, with a flyback diode if the motor does not already include one.
How do I choose a solenoid valve for watering?
Pick the coil voltage matching your power supply (12 V or 24 V), a fitting diameter compatible with your hose, and check the minimum opening pressure, since some valves need water pressure to open properly.
Why do prices vary so much from one pump to another?
Flow rate, delivery head, motor type (brushless being more durable and quieter than a brushed motor) and the housing's sealing largely explain the difference.
Can I pick up my order in person?
Yes, pickup is available at the Bab Ezzouar store in Algiers, and delivery is provided to all 58 wilayas via Yalidine.
