QDX Aluminium Body Automatic Submersible Pump with Float Switch

This is a practical automatic submersible pump made for draining and moving water without constant supervision. The aluminium body keeps it light and corrosion-resistant, while the built-in float switch handles the on/off control. It works well in homes, small commercial sites and light industrial jobs where you just need reliable water management.

Automatic operation with float switch

The float switch is the main convenience feature. When the water level rises the pump starts; when the level drops it stops by itself. No need to stand there watching it. This stops the pump from running dry and saves a lot of manual checking. It's useful in basements, tanks, wells and outdoor drainage spots. The automatic control also helps the pump last longer because it only runs when needed.

Aluminium body

The housing is aluminium alloy—light enough to carry around easily but still resistant to corrosion. That combination makes it handy if you need to move the pump between locations. Inside, the parts are also protected against rust so it keeps working through repeated use.

Submersible design

The pump is meant to sit fully under water. Being submerged keeps the noise down and lets the surrounding water cool the motor naturally, which reduces overheating risk. You don't have to prime it or set up complicated suction lines, so installation stays simple. The motor has basic protection built in for normal working conditions.

Typical uses

• Residential: basement drainage, garden water movement, simple irrigation transfer
• Commercial and construction: dewatering sites, clearing stormwater, temporary flood control
• Light industrial and municipal: tank transfer, rainwater collection, small circulation systems
• Because of the float switch it can run unattended, which is the main reason people choose it for these jobs.
