UP501/A Automatic Submersible Pump with Non-Return Valve 32 l/min
51,00 €
The new automatic submersible pumps, available in 12V and 24V, guarantee fast installation, easy maintenance and reliable operation, even in harsh onboard conditions. Integrated electronics enable continuous water presence monitoring and automatic pump activation without the use of float switches, increasing overall system reliability and reducing the number of external components subject to wear or failure. The motor–impeller bayonet coupling design allows motor replacement without disconnecting hoses or removing the pump body from the bilge, reducing intervention time and simplifying maintenance. The multifunction hose fittings, compatible with two hose diameters, ensures installation flexibility for both new installations and retrofit projects. The integrated check valve prevents water backflow and guarantees complete bilge drainage, improving system efficiency and reducing unwanted activations. ISO 8849 and ISO 8846 certified.

Installation notes
Install a correctly rated fuse (6 A on 12V, 4 A on 24V). Installing the fuse is compulsory.
Brown (+) wire to the positive battery terminal, black (-) wire to the negative terminal.
Automatic function: when the Brown/White cable is connected to (+), the sensor checks every 2.5 minutes whether there is water by running for 0.5 s. In automatic mode do not connect the brown cable to (+).
Make the electrical installation in a dry place to avoid contact with water.
Use correct bilge pump hose, keep the hose run as short and steep as possible to avoid air locks, and fix hoses with stainless steel clamps.
Mounting: lift the power module out of the strainer, fix the strainer with stainless steel screws, then insert the power module back onto the strainer.
