Unique-Bargains Micro Submersible Mini Water Pump DC 4.5V Vertical Pack of 2

SKU CH-YKWY-JHVZA

Two vertical DC 4.5V submersible pumps deliver 100 L/H flow with 55 cm lift for small fountains and automatic plant watering

  • Low power draw extends battery life with 0.91W consumption
  • Compact 45x39mm footprint fits tight project spaces
  • 100 L/H flow rate suits small fountains and plant watering
  • 55cm max lift handles vertical installations easily
  • Twin-pack provides ready spare or dual-point supply

Compact DC 4.5V pump pair for DIY projects

Two vertical-style submersible pumps deliver a maximum flow of 100 L/H and a lift of 55 cm from a 4.5 V supply drawing 0.18 A. The 45 x 39 mm footprint suits small fountains, automatic plant watering and other low-flow DIY builds.

Pack of two simplifies dual-point setups

Having two identical units in one pack lets you run separate water features or provide a ready spare without sourcing a second pump separately. Each pump includes a 23 cm lead and a 6.35 mm outlet for quick tubing connection.

DC 4.5V voltage limit is the critical spec

The pump must operate at exactly 4.5 V DC; over-voltage, dry running, acidic or alkaline fluids and particles larger than 0.35 mm are all prohibited. Buyers who need higher flow, greater lift or a different supply voltage should look elsewhere.

Questions about this item

How often should I clean the 6.35mm outlet and internal parts to prevent debris larger than 0.35mm from damaging the pump?

Clean the pump and replace the water solution whenever debris is visible, as particles over 0.35mm can cause damage if not removed promptly.

Will the 0.91W motor overheat if I run the pump continuously at the 100 L/H flow rate?

The pump must remain submerged during operation; running it dry for extended periods is prohibited and will cause overheating and failure.

How much heat does the 0.18A current generate when the pump runs all day in a small fountain?

At 0.91W power draw, heat output is minimal; the surrounding water provides adequate cooling as long as the pump stays fully submerged.
