The MARCO UPE pumps are electronically controlled freshwater gear pumps designed for pressurized onboard water systems. They deliver constant water pressure without pulsation, operate quietly, save space, and are suitable for multiple outlets.The MARCO UPE pumps are self-priming gear pumps with electronic speed control and smooth, gradual start-up. Their speed automatically adjusts to the water demand, eliminating pressure fluctuations and pulsation in the system. An accumulator tank is only required when using rigid or very short pipes or solenoid valves.The pump housings are made of nickel-plated brass, and the spindles are stainless steel. The durable PEEK gears ensure high pressure, quiet operation, and excellent temperature resistance. Integrated non-return valves are included as standard. The pumps support both 12 V and 24 V operation. Connections are BSP female threads, and each pump is supplied with matching stainless-steel hose tails.The electronic control enables soft start and stop, reducing power consumption and water waste while significantly extending component life — up to three times longer than comparable models. The electronic system constantly monitors pressure, current, and voltage, provides protection against short circuits and overvoltage, and automatically stops the pumps when the tank is empty.These pumps run very quietly, require minimal space, and ensure reliable water supply on board.Models:· Type UP2/E: for max. 2 outlets, without pre-filter· Type UP3/E, UP6/E, UP12/E: for max. 3 outlets, with pre-filter· Type UP14/E: for max. 3 outlets, with pre-filter and PCS control panelKey Advantages at a Glance:· Electronic speed control, adjusts to water demand· Smooth, gradual start and stop· No pressure fluctuations, no pulsation· Self-priming (not dry self-priming)· No accumulator tank required except with rigid/short pipes or solenoid valves· PEEK gears: high pressure, quiet running, temperature resistant· Integrated non-return valves· Electronic monitoring of pressure, current, voltage· Protection against short circuit and overvoltage· Automatic shut-off when tank is empty· Multi-voltage: 12 V / 24 V· BSP female thread connections, incl. stainless-steel hose tails· Very quiet operation· Robust materials: nickel-plated brass, stainless steel
