Boat pump UP501/A

marinebilgeseawater

Description
The UP501/A is an automatic submersible bilge pump available in 12 V and 24 V versions, designed for fast installation, simplified maintenance and reliable operation in demanding marine environments. Integrated electronics continuously detect water presence and trigger automatic pump start without float switches, reducing moving external components and improving system reliability. The motor–impeller bayonet coupling enables motor replacement without disconnecting hoses or removing the pump body from the bilge. Multifunction hose fittings accept two hose diameters for flexible new-install and retrofit applications. An integrated check valve prevents backflow and ensures complete bilge drainage. Certified to ISO 8849 and ISO 8846.
