4SP stainless steel multi-stage deep well submersible pump is a new type of machine for extracting groundwater.

It is widely used in industrial and mining enterprises for water supply, irrigation of farmland, and groundwater for self-use.

Since the pump main body is made of stainless steel or copper alloy, it has anti-corrosion,

Wear-resistant, energy-efficient, and fully reliable, and because of its compact structure,

Small size and light weight, very easy to maintain, transport, install and use, and automatic section

It can be used with control box, with protection against over temperature, short circuit, overload and under voltage.

Safe and reliable to use.

Main Feature

1. All stainless steel material structure is pollution-free and corrosion-resistant.

2. small outer diameter, high lift, large flow, high efficiency and energy saving, all stainless steel materials, long service life.

3. Built-in all-stainless steel check valve can effectively prevent the water hammer from damaging the pump when the motor is stopped.

4. Precision-processed all-stainless steel allows the pump to maintain good performance under high pressure.

5. high efficiency all stainless steel impeller is the biggest feature of this product, in terms of wear resistance and service life is significantly better than ordinary plastic impeller and brass impeller.

6. The all-stainless sand filter net can prevent sand or large particles from entering the pump body.
