Mini submersible pump 2.5-6V 120L/h, vertical

Product detailed description

The Mini Submersible Pump 2.5–6 V is a small and quiet water pump with a flow rate of up to 120 litres per hour, which can be powered simply via USB or batteries. It is suitable for small fountains, automatic flower watering, hydroponics, animal waterers, as well as school and hobbyist projects. The motor is encased in a plastic body and the pump is fully submersible – the outlet is directed vertically upwards, making it ideal for areas with limited width (narrow containers, flower pots, fountains). When using an Arduino or ESP32, you must switch it via a transistor, MOSFET, or relay; it cannot be powered directly from a microcontroller pin.

Specifications:

• Pump type: submersible, vertical (top outlet), with DC motor
• Power Supply:
  • Voltage: 2.5–6 V DC (recommended 3–5 V)
  • Current draw: typically approx. 100–200 mA, up to 1 A briefly during startup
• Performance:
  • Flow rate: 80–120 l/h
  • Maximum head: 40–110 cm (depending on supply voltage)
  • Output: 1 outlet – power is sufficient for a single hose; the pump cannot handle splitting into multiple branches
• Hose outlet:
  • Outer diameter: 7.5 mm
  • Inner diameter: 4.7 mm
  • Suitable tubing:
    • Silicone tubing 9/7 mm
• Microcontroller control:
  • switching via transistor, MOSFET or relay (an Arduino/ESP32 pin cannot provide this current)
  • connect a protection diode and a 100 nF capacitor in parallel with the motor – this limits noise that could reset the microcontroller or disrupt the display during motor startup
• Dimensions: approx. 38 × 24 × 43 mm
• Supply leads: approx. 20 cm – expect to extend them in most installations
• Lifespan: approx. 500 hours (manufacturer's data)
• Operation: submerged in liquid only; must not run dry
• Other versions:
  • Mini submersible pump 2.5-6V 120L/h, horizontal
  • Mini submersible pump 2.5-6V 120L/h, submersible and external, white
• Variants:
  • white
  • black

Package contents:

• 1× mini submersible pump 2.5–6 V, 120 l/h, vertical (depending on the chosen colour)

Note:

• The pump must not run dry – operation without liquid will cause permanent damage.
• Not intended for pumping flammable liquids, acids, or liquids containing solid impurities.
• This is an affordable hobby pump – for continuous year-round operation, choose a more powerful type.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
