Mini submersible pump 2.5-6V 120L/h, submersible and external, white

Product detailed description

This 2.5–6 V mini pump with a flow rate of up to 120 litres per hour can be used both submerged in water and outside the tank, as it features its own suction and discharge outlets for tubing. It is powered via USB or batteries and is suitable for small fountains, automatic irrigation, hydroponics, water cooling or transferring liquids between containers. The intake is located on the pump axis, the outlet is directed upwards, and the bottom foot facilitates attachment to a surface. 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: centrifugal with DC motor, for both submersible and external (out-of-tank) use
• Power Supply:
  • Voltage: 2.5–6 V DC (recommended 3–5 V)
  • Current consumption: typically approx. 100–220 mA, up to 1 A briefly during start-up
• 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 outlets:
  • Suction: tube in the pump axis
  • Discharge: tube facing upwards, outer diameter 7.5 mm, inner 4.7 mm
  • Suitable tubing:
    • Silicone tubing 9/7 mm
  • Suitable suction filter:
    • Suction filter with mesh for tubing, 8mm – when used outside the tank, it protects the pump from impurities
• External use: the pump is not self-priming – place it below the level of the pumped liquid to ensure the intake remains flooded
• 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
• Supply leads: approx. 20 cm – expect to extend them in most installations
• Lifespan: approx. 500 hours (manufacturer's data)
• Color: white
• Other versions:
  • Mini submersible pump 2.5-6V 120L/h, horizontal
  • Mini submersible pump 2.5-6V 120L/h, vertical

Package contents:

• 1× mini pump 2.5–6 V, 120 l/h, submersible and external, white

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.
