MarinAire Pumps stand at the extreme edge in the field Hi-Tech Magnetic Pumps. MAP series pumps designed to pump fresh water, salt water, highly corrosive chemicals and solutions. MAP series feature leak proof, seal-less magnetic drives and are designed for in-line, non-submersed use. They have a unique design with stylish appearance. In particular, it"s bearing adopt ceramic material with special formula featuring strong resistance to abrasion and corrosion. MAP series also feature low power consumption, low starting current and high energy efficiency.IMPORTANT!This is not a submersible pump.This is not a self priming pump. For marine air conditioning applications; the pump should be installed under the water line. For any other application; the liquid should always be available at the pumps water inlet.This pump will not suck liquid from a tank which is located below the pump. The pump should be located below the tank so that the liquid may flow to the pump naturally with gravity.
