4SP type stainless steel multistage deep well submersible pump is a new high-grade machine for getting underground water. It is widely used for water supply and discharge in industrial and mining enterprises, for farm land irrigation, for getting underground water for private use. The main parts of the pump are all made of stainless steel and copper alloy, so has such features as anti-corrosion, wear resistance, energy-saving, high efficiency and fully reliable. Besides, as it has compact structure, small and light, it is easy to maintain, transport, install and use. When used in combination with automatic energy-saving high efficiency control box, it can be protected against over temperature, short circuit, over load and under voltage, safe and reliable to use.
