Circulation Pump Wilo TOP-S 50/10

The Wilo TOP-S 50/10 is a maintenance-free, glandless circulation pump designed for hot-water heating systems, air-conditioning systems, closed cooling circuits, and industrial circulation applications.
The pump features a durable cast-iron housing with a cataphoretic coating for corrosion protection, a stainless steel shaft, and a glass-fiber-reinforced polypropylene impeller. Its DN 50 combination flange (PN 6/10) allows installation in compatible piping systems.
The Wilo TOP-S 50/10 series includes both single-phase (1~230 V) and three-phase (3~400 V) versions. The single-phase model features two manually selectable speed settings, while the three-phase model provides three speed settings for adjusting pump performance to system requirements.
Both versions are designed for reliable circulation of heating water and suitable water-glycol mixtures. Thermal insulation and motor protection features support operation in heating and circulation systems.
