What are pressure pumps and what are they used for?
Pressure pumps are compact devices (usually diaphragm type) that maintain constant pressure in the internal water network. They are used to supply consumption points in homes, boats, motorhomes, and off-grid systems. In this collection you will find 12/24 V DC versions—perfect for solar use with batteries—and 230 V AC options for installations with grid or generator. They are complemented by Ibaiondo pressure tanks, inlet filters, and original spare parts.
Advantages and limitations
- Efficiency and control: integrated pressure switch/press-control that starts and stops according to demand, reducing consumption.
- Simple installation: self-priming, compact size, and accessible maintenance.
- Electrical versatility: 12/24 V ranges for batteries and 230 V for grid.
- Limitations: do not replace a submersible pump for high lift or a pool filter; their job is the pressurization of the internal network.
Common applications
- Isolated homes or with photovoltaic support (tap, shower, washing machine with intermediate tank).
- Marine and camper: fresh water supply with low consumption and contained noise.
- Light irrigation systems and pressurized transfers between nearby tanks.
How to choose your pressure pump
- Nominal flow rate (l/min): estimate simultaneous points (e.g., 6–10 l/min for 1–2 points; 12–19 l/min for 2–3).
- Pressure (PSI/bar): match with piping and accessories (usually 30–60 PSI; up to 100 PSI in specific models).
- Voltage: 12 V for small/camper systems, 24 V for longer runs and lower current, or 230 V if you have grid or inverter.
- Comfort and durability: add a pressure tank to reduce cycles and water hammer; install an inlet filter to protect the diaphragm.

Best practices
- Use appropriate cable section and fuse at the input; for 12 V, pay attention to voltage drop.
- Install a filter before the pump and purge air from the line at first start-up.
- Install a pressure tank (20–50 L for domestic use) for fewer starts, less noise, and longer pressure switch life.
- Adjust the cut-off pressure if the model allows, according to the internal network.
- Periodic inspection of connections, seals, and diaphragm condition; keep critical spare parts (pressure switch, valves, diaphragm) available.
Comparisons and related accessories
If you need to draw from a well, see submersible pumps. For transfers from tanks without submerging the equipment, check surface pumps. Improve your installation with accessories (Ibaiondo pressure tanks, filters, probes, and DC protections) and find original parts in spare parts. You can return to the overview at Water Pumps.
