This Liberty D3600-Series duplex grinder package is built around two 2 HP Omnivore grinder pumps, wired for single-phase power at 208-230V, in a 36" x 60" fiberglass basin with an anti-flotation collar and a factory pre-assembled guide rail system. It ships complete with discharge piping, integral check valves, ball valves down to a 2" discharge, a QuickTree pre-mounted float switch system, a standard green fiberglass cover, a 4" inlet hub with rubber pipe seal, stainless steel supports and brackets, a pre-mounted NEMA 4X junction box, and a stainless steel lift-out chain. Includes a 35' power cable and an external capacitor. Ships standard with a Liberty AE-Series control panel — three level control floats alternate the load between the two pumps.
