OHI PRO 25-80/180 - circulation pump
The OHI PRO 25-80/180 circulation pump features a glandless design with a ceramic shaft offering extended service life. Each unit undergoes robotic production with quality control at every stage, as well as final electrical and hydraulic testing, which has made it possible to extend the warranty period to 3 years.
Who is it for?
- Central heating installers – the robust construction and complete set of union fittings included shorten installation time and reduce the number of complaints.
- Owners of single-family homes looking for a solution for years to come – the extended 3-year warranty reflects the increased durability of the components used.
- Owners of installations with limited space – thanks to its compact size, the OHI PRO pump fits into confined spaces.
Applications
The OHI PRO circulation pump forces the circulation of clean water in domestic and professional installations, reducing the waiting time for hot water at water outlets. Three adjustable speeds allow the performance to be matched to a specific installation, from small single-family systems to larger installations requiring greater head and capacity.
The 80/180 and 100/180 variants stand out with higher operating parameters than the smaller models in the series while retaining the same design and installation kit. The OHI PRO 25-80/180 230V circulation pump is powered from a standard domestic electrical outlet.
Features
The high-density ceramic shaft and plain bearings reduce wear on the pump’s moving components compared with typical solutions used in circulation pumps. The motor winding, made with stronger Class F insulation, increases motor durability and improves electrical performance, while the glandless design provides increased resistance to failure for the entire unit.
The robotic production process, with quality control of semi-finished products at every stage, together with final electrical and hydraulic testing of each unit, results in consistently high manufacturing quality. These solutions have enabled 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 clean water in domestic and professional installations, keeping water warm at water outlets without long waiting times. Three adjustable speeds allow its operation to be matched to the conditions of a specific installation.
How does OHI PRO differ from a standard OHI pump?
OHI PRO uses a high-density ceramic shaft and plain bearings, and each unit undergoes robotic production with final electrical and hydraulic testing. Thanks to the increased durability of its design, the OHI PRO series comes with a 3-year warranty, compared with the 24-month warranty of standard OHI pumps.
How do I choose the right OHI PRO model for my installation?
The choice of model depends on the required head and capacity of the installation – 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 higher operating parameters for larger or more demanding systems. Detailed parameters for individual models can be found in the product technical data tab.
Does the OHI PRO pump come with installation union fittings?
Yes, each OHI PRO pump is supplied with a complete set of union fittings and a power cable with a plug, allowing the unit to be installed without selecting additional accessories.
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. Dambat provides warranty and post-warranty service.
