Description

Drop the pump into water, connect a tube to the outlet and switch it with a relay or MOSFET – that's a complete automatic watering system. It runs happily from a 5 V USB supply or 4 AA cells.

Features

  • Operating voltage 3–6 V DC
  • Current about 100–200 mA
  • Flow about 80–120 litres per hour
  • Lift height about 40–110 cm
  • Outlet outer diameter about 7.5 mm (fits 5 mm inner-diameter tube)

Good to know

The pump must be fully under water while running – running dry damages it. Use clean water only (no oil or thick liquids). Tube not included.

1 × mini submersible pump with wires
