Who it's for
- Heating system installers - the sturdy design and included set of unions shorten installation time and reduce the number of complaints.
- Single-family homeowners looking for a long-lasting solution - the extended 3-year warranty reflects the enhanced durability of its components.
- Owners of systems with limited space - the compact OHI PRO pump fits into tight spaces.
Applications
The OHI PRO circulation pump circulates clean water in residential and commercial systems, reducing the wait for hot water at outlets. Three adjustable speeds let you match the flow rate to the specific system, from small single-family home systems to larger installations requiring greater head and flow.
The 80/180 and 100/180 models offer higher performance than the smaller models in the series while retaining the same design and installation kit. The OHI PRO 25-40/180 230V circulation pump is powered by a standard household outlet.
Features
The high-density ceramic shaft and plain bearings reduce wear on the pump’s moving parts compared with typical solutions used in circulation pumps. The motor winding’s Class F insulation provides greater motor durability and improves electrical performance, while the glandless design increases the overall unit’s resistance to failure.
The robotic production process, with quality checks of semi-finished products at every stage, and final electrical and hydraulic testing of every unit ensure consistent build quality. These solutions have enabled the manufacturer to extend the standard warranty to 3 years for the entire OHI PRO series.
