CPI 15-15 – circulation pump for technically clean water
The IBO CPI 15-15 circulation pump eliminates frustrating waits for hot water at the tap – it forces the continuous circulation of heated, technically clean water through the installation, so hot water flows almost immediately after the valve is opened instead of cooled water from the pipes.
Who it's for
- Homeowners with long installation runs – reduce the waiting time for hot water and limit water waste every time the tap is turned on.
- Installers – the glandless, compact design and the ability to rotate the terminal box make installation in tight spaces before the boiler easier.
- Boiler and storage tank owners – the pump is selected as the component that forces circulation before the hot water tank.
- Service companies – the simple, single-speed design without electronics means fewer components that can fail.
Applications
The CPI 15-15 circulation pump is designed to force the circulation of heated, technically clean water in installations supplied by a boiler or storage tank. It is usually installed before the tank, on the supply side, and operates in liquid temperatures of up to 95°C.
As a result, in installations without forced circulation, where turning on the tap first releases cooled water from the pipes and only then hot water, the CPI 15-15 230 V circulation pump provides hot water almost immediately after opening the valve, without unnecessary waste of water and energy.
Features
The brass body and ceramic shaft provide resistance to corrosion and limescale buildup, allowing the pump to operate almost trouble-free for many heating seasons. Materials that come into contact with water have a PZH certificate, confirming their safety in technically clean water installations with high temperatures. The terminal box can be rotated relative to the pump body, allowing the power cable to be routed vertically downward and protected against flooding in the event of an installation leak.
The pump must operate with the shaft positioned horizontally – installation in a vertical position leads to rapid bearing wear, so it is worth planning the correct positioning on the pipeline before the boiler right away. The single-speed design without control electronics means fewer components that can fail and simpler installation than with mult speed pumps.

Frequently asked questions
What is the CPI 15-15 circulation pump used for?
The CPI 15-15 forces a constant circulation of clean technical hot water through the installation, so when the tap is opened, hot water appears almost immediately instead of cooled water that has been standing in the pipes.
Is the CPI 15-15 suitable for central heating systems?
No—the CPI 15-15 is specifically designed for circulating clean technical hot water and is installed upstream of a water heater or storage tank, not for forcing circulation in central heating systems.
Will the CPI 15-15 pump work well in my installation?
Yes, provided that the distance and resistance of the installation are within the 1.7 m head range and the water temperature does not exceed 95°C—the pump performs well in typical single-family-home installations with a water heater or storage tank.
How should the CPI 15-15 pump be installed correctly?
It is essential to position the pump shaft horizontally—vertical installation quickly damages the bearings. The terminal box should be positioned so that the cable exits vertically downward, protecting it from flooding in the event of a leak in the installation.
Where can I buy the CPI 15-15 circulation pump?
The pump is available from our trade partners, plumbing wholesalers, and authorized online distributors.
What warranty applies to the CPI 15-15 pump?
The IBO pump comes with a 24-month manufacturer's warranty, while Dambat provides warranty and post-warranty service.
