Automatic cistern pumping without a pressure tank
The Springer Series automatic cistern pump is a drop-in water supply option for cabins, small homes, frost-free hydrants, and spigots. Its internal pressure and flow controls start the pump when water is demanded, without an external pressure switch or pressure tank for these applications.
Free shipping to the contiguous 48 U.S. states.

Is this the right pump?
Choose this pump for direct supply from a cistern or water tank to a small home, cabin, hydrant, spigot, or hose. It is not recommended for drip irrigation or uphill runs greater than 60 ft. For those applications, use a suitable pump setup with a pressure tank and external controls.
