Corrosion resistant submersible pumps are a reliable and efficient solution for pumping water and other liquids from deep wells, boreholes, and water tanks. These pumps are made with materials that can withstand harsh environments and resist corrosion, such as stainless steel and thermoplastic. They are ideal for use in agricultural, industrial, and domestic applications where water quality is poor or where the pump is exposed to corrosive substances. With their ability to operate underwater, corrosion resistant submersible pumps are also suitable for use in flooded areas.

Frequently Asked Questions (FAQs)

1. Will a submersible pump rust?

Cast iron submersible pump components corrode quickly when exposed to these chemicals, particularly when they are in high concentrations or at elevated temperatures. However, stainless steel submersible pumps withstand corrosion far longer because of their higher chemical resistance.

2. How long should a submersible pump last?

The main factors affecting the longevity of your submersible well pump are: the water quality, the quality of pump selected, the competency of the installation and the quality of the power provided to the well pump motor. Industry averages show that submersible well pumps last, on average, about 7 years.
