Vai al moduloMarco UP3/E is a 12/24 V electronic water pressure system for the fresh water supply on boats, yachts, dinghies and campers. It is a self-priming pump with helical gears, an integrated check valve and electronic pressure control: the sensor adjusts the motor speed to the water demand and keeps the pressure constant. Flow rate 15 l/min, pressure 2.5 bar, nickel-plated brass body and stainless steel shaft. Marco code 16460215.
Main features
- Universal 12/24 V DC supply: the same model works on 12 V and 24 V systems
- Constant pressure thanks to variable-speed electronic control
- Self-priming up to 1.5 m, with integrated check valve
- Automatic stop when the water runs out, plus short-circuit and overvoltage protection
- Gradual motor start-up: less noise and less electrical interference
- LED indicators for operating status

Where it is used
Water pressure system for fresh water installations and shower systems on motor boats, sailing boats, yachts, dinghies and campers. With 15 l/min and 2.5 bar it suits installations with several outlets open at the same time, for example a sink, a shower and a galley. For more compact installations, see the Marco UP2/E 12 l/min. The model is also available with a control panel.
UP2/E or UP3/E: which one to choose
| Feature | UP2/E | UP3/E |
|---|---|---|
| Flow rate | 12 l/min | 15 l/min |
| Pressure | 2 bar | 2.5 bar |
| Motor power | 90 W | 150 W |
| Fuse | 7.5 A | 15 A |
| Hose diameter | 12 mm | 13 mm |
| Weight | 1.3 kg | 2 kg |
| Voltage | 12/24 V DC | 12/24 V DC |
| Priming height | 1.5 m | 1.5 m |
| Ports | 3/8" BSP | 3/8" BSP |
The UP3/E offers more flow and more pressure for installations with several outlets open at once. The UP2/E is the choice for compact installations and low power consumption.
Frequently asked questions
Does the UP3/E work on both 12 V and 24 V?
Yes. The supply is universal 12/24 V DC: you do not need different versions for 12 V or 24 V systems.
Is a pressure tank needed?
In most installations it is not, because the electronic control keeps the pressure constant. With short, rigid pipes or solenoid valves, an expansion tank of at least 0.5 l is recommended to avoid water hammer.
Which fuse should I fit?
A 15 A fuse.
What happens if the water tank runs empty?
The pump stops automatically when there is no liquid.
What is the difference between the UP2/E and the UP3/E?
The UP3/E delivers 15 l/min instead of 12, works at 2.5 bar instead of 2 and has a more powerful motor (150 W versus 90 W). Both are 12/24 V, self-priming and electronically controlled.
