Johnson Marine Bilge Pumps – Cartridge L450-L750 & Ultima Combo

Model: L450UC-L750UC

These pump series consists of four different sizes. The basic version can be combined with either an automatic switch AS888, an electronic float switch or the new ULTIMA switch for automatic operation. The Cartridge Duo pumps are equipped with a non-clogging electronic float switch as standard.

For L450, L550, and L650 and dito Ultima Combo versions, we have improved the design with easy-to-install Dura-Port discharge ports to eliminate stress cracking caused by over-tightened hose clamps. The pumps will be delivered including both a straight and a 90° smooth elbow Dura-Port as well as a removable check valve.
