Atlantic's TidalWave L-Series are axial flow pumps, designed to deliver high water volumes through large diameter plumbing to relatively low heights. At under 10 ft. of head, the low power consumption of these 3-inch male threaded outlet pumps can’t be beat for your high flow applications. Built with the same robust cast iron and stainless steel construction as Atlantic's A-Series, the L-Series pumps are built to last, and will continue to deliver for years.

This is a precision manufactured motor with thermal overload protection, which shuts off the pump in low water conditions, preventing damage. Made with double silicon carbide mechanical seals, as well as dual drive bearings. Backed by a 2-year manufacturer warranty.
