OHI PRO 25-40/180 - circulation pump
The OHI PRO 25-40/180 circulation pump has a glandless design with a ceramic shaft with increased durability. Each unit undergoes robotic production with quality control at every stage and a final electrical and hydraulic test, which allowed the warranty period to be extended to 3 years.
For whom
- Central heating installers and domestic hot water – solid construction and a set of screw connections included in the set shorten the assembly time and reduce the number of complaints.
- Owners of single-family houses looking for a long-term solution - the extended, 3-year warranty reflects the increased durability of the components used.
- Managers of utility water circulation installations - the National Institute of Hygiene (PZH) certificate confirms that the pump is approved for contact with utility water.
- Companies installing heating and cooling installations - the OHI PRO pump works with both heating water and glycol-based antifreeze.
Application
The OHI PRO circulation pump forces circulation of utility water in home and professional hot water installations, limiting the waiting time for hot water at the draw-off points. Three adjustable gears allow you to tailor capacity to your specific installation, from small single-family systems to larger installations requiring higher lift and capacity.
The OHI PRO design also enables operation in heating and cooling installations with glycol-based antifreeze, which expands the scope of applications beyond typical hot water circulation. The variants marked 80/180 and 100/180 are distinguished by improved operating parameters compared to the smaller models of the series, while maintaining the same structure and assembly kit. The OHI PRO 25-40/180 230V circulation pump is powered from a standard home installation socket.
Features
A ceramic shaft with increased density and sliding bearings reduce wear of the pump's moving elements compared to typical solutions used in circulation pumps. The motor winding made with stronger Class F insulation increases the durability of the motor and improves electrical parameters, and the glandless design eliminates the most failure-prone element of the traditional circulation pump.
The robotic production process with quality control of semi-finished products at each stage and the final electrical and hydraulic test of each item translate into repeatable quality of workmanship. These solutions allowed the manufacturer to extend the standard warranty period to 3 years for the entire OHI PRO series.

Frequently asked questions
What is the OHI PRO circulation pump used for?
The OHI PRO circulation pump forces the circulation of utility water in home and professional hot water installations, thanks to which the water at the draw-off points remains warm without long waiting times. Three adjustable gears allow you to adjust its operation to the conditions of a specific installation.
How does OHI PRO differ from the standard OHI pump?
OHI PRO uses a high-density ceramic roller and plain bearings, and each unit undergoes robotic production with a final electrical and hydraulic test. Thanks to the increased durability of the structure, the OHI PRO series is covered by a 3-year warranty, compared to the 24-month warranty of standard OHI pumps.
How to choose the right OHI PRO model for your installation?
The choice of model depends on the required lift and installation efficiency - smaller models (e.g. 15-60/130, 25-40/180) are suitable for typical single-family installations, while the 80/180 and 100/180 variants offer increased operating parameters for larger or more demanding systems. Detailed parameters of individual models can be found in the product technical data tab.
Can OHI PRO pumps be used in glycol installations?
Yes, the OHI PRO design allows operation in both water-based heating systems and cooling systems with glycol-based antifreeze.
Does the OHI PRO pump kit include mounting screws?
Yes, each OHI PRO pump is supplied with a set of screw connections and a power cord with a plug, which allows you to install the device without the need to select additional equipment.
What is the warranty on OHI PRO pumps?
IBO OHI PRO series circulation pumps are covered by a 36-month (3-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
