Powered by an 18V lithium battery, the Cordless Portable Submersible Water Pump operates independently without mains power.Compact and lightweight, with a hangable battery box, it can be easily carried and placed by one person.It can be used flexibly in remote outdoor areas, construction sites, balconies, courtyards and other locations, achieving true anytime, anywhere pumping.
Equipped with a patented sealing structure that provides superior waterproof performance compared to ordinary pumps.It effectively prevents water ingress, avoids short circuits and motor damage, and ensures stable long-term underwater operation.
The pure copper motor features higher conductivity, lower heat and less loss than ordinary aluminum-wire motors, ensuring stable output during long continuous operation.The aluminum alloy housing provides excellent heat dissipation, corrosion resistance and impact resistance, suitable for harsh outdoor environments.
● Over-voltage & under-voltage protection
● Over-current protection
The system automatically cuts off power when abnormal voltage or current is detected, preventing motor burnout, battery damage and safety hazards, protecting both the device and the user.
The Cordless Portable Submersible Water Pump comes with a telescopic pipe that can be freely adjusted to match different water levels and scenarios without extra accessories.The standard G1" interface fits most common hoses and nozzles, supporting pumping, drainage, cleaning and watering.
The base adopts a tool-free quick-release design for easy removal and cleaning of the internal filter screen.When clogged by sand or debris, users can quickly disassemble, clean and reassemble, reducing maintenance cost and ensuring stable pumping efficiency.
With an 18V/4AH lithium battery, the pump supports up to 48 minutes of continuous operation per charge.The battery box is hangable and portable.Battery platform customization (capacity, voltage, connector) is available for different markets.
This Cordless Portable Submersible Water Pump is widely used in household, outdoor, construction and garden scenarios:
