Product Overview
The WILO TOP-RL25/8,5 (Part No. 2065523) is a high-efficiency glandless circulator pump engineered by WILO, a global leader in pump technology. This model operates on a wet-rotor, glandless principle, where the motor rotor is directly immersed in the pumped medium, eliminating the need for a mechanical shaft seal and thus preventing leakage. Designed for industrial and building services applications, it provides reliable, maintenance-free circulation of fluids in closed-loop systems. Its compact inline design and integrated electronic control make it ideal for precise flow management in heating, cooling, and industrial process circuits.
