10617
The LEO LRP32-50/180 is a robust circulation pump engineered for demanding heating, ventilation, and air conditioning (HVAC) systems as well as domestic and industrial hot water circulation. Built on decades of LEO's expertise in reliable pumping solutions, this versatile circulation pump excels in central heating systems, district heating networks, solar-powered hot water pressure boosting, and auxiliary industrial cooling and heating applications where consistent flow and dependable performance are essential.
Constructed with a durable cast iron or brass pump body paired with a heat-resistant Noryl impeller capable of handling temperatures up to 150 degC, the LRP32-50/180 delivers exceptional longevity in challenging thermal environments. Its advanced 95% alumina ceramic shaft and matching ceramic bearings resist corrosion and wear, while the copper-wound motor with IP44 enclosure protection and three-speed operation provides both flexibility and reliability for continuous circulation duty across liquid temperatures ranging from 2 degC to 110 degC.
