The Demco 48-foot liquid tender provides an extended service deck between two bulk liquid tanks. The additional deck room is useful when a sprayer-support trailer needs space for pumps, mixing equipment and other filling supplies.
The listed package includes Basic plumbing from the tanks to a central fill and valve bank. It does not include a pump or mixing inductor as part of that Basic package. Ladders, sight gauges, side storage bins, auxiliary power and air connections, and sealed LED lighting support the daily filling routine.
