1、 Overview of QDN Small Stainless Steel Submersible Pump:
Stainless steel submersible pumps use single-phase (three-phase) power supply, with special materials for sealing components, strong corrosion resistance, low noise, and long service life. They are mainly used in national water-saving drip irrigation, sprinkler irrigation, and micro irrigation projects, providing deep water sources, supplying drinking water to high-rise buildings, and used on purification machines.
In addition, the stainless steel submersible pump has a built-in stainless steel structure, which is small in size, beautiful in appearance, rust resistant, and corrosion-resistant. It can be used in general acidic and alkaline seawater. (pH value 1-10) Suitable for industries such as medicine and food. QDN fully automatic stainless steel submersible pump is a fully automatic clean water submersible pump with a floating ball, which has the advantages of automatic liquid level control and easy operation.
