The Diaphragm is a positive displacement,continuous duty pump which is capable of twenty ft. of suction (self priming to 8 ft.) and is available in 12V or 24V DC.
It is an excellent, economical pump for smaller livestock numbers or cottage application, pumping from a surface body of water or suspended above the water in a well.
It can be controlled by a float switch, or because it is equipped with an internal pressure switch, it can operate with an optional tank to create a pressure system. As a positive displacement pump it requires freeze protection.
