The SQ2-series is a submersible stainless steel portable corrosion resistant pump designed for handling screened wastewater or clean water. The major wetted parts are made of 304/316 stainless steel and resin. The top discharge, flow-thru design always cools the motor with the pumped media and allows the pump to operate at low water levels for extended periods. Liquid paraffin is used for the lubricating oil, which enables the application of the SQ2-series to the food or aquaculture industry
