Heating circulation pump Wilo TOP-S 50/7 EM

Heating circulation pump Wilo TOP-S 50/7 EM

Wilo TOP-S circulation pumps circulate water in heating, hot water and floor heating systems. Wilo TOP-S circulation pumps are quite compact and lightweight, installed directly on the pipeline and operate almost silently. Suitable for systems of almost all private houses, not easy to install and have a long service life. The installation of the electronic high-efficiency pump Wilo TOP-S saves up to 90% of energy compared to an unregulated circulation pump. If you use the Wilo TOP-S pump in the hot water supply system, then the energy savings compared to standard circulation pumps will be 80%. Pumps of this line are designed for installation in private houses and cottages.

Equipment and functions of Wilo TOP-S circulation pumps:

• Manual power adjustment with 3 speed settings
• Wilo TOP-S pumps with single-phase motor:

• P ₂ up to 90 W: Integrated winding protection against overheating
• P ₂ = 180 W: Complete motor protection by winding safety contact in combination with tripping device

• Wilo TOP-S pumps with three-phase motor:

• P ₂ up to 90 W: Integrated winding protection against overheating
• P ₂ ≥ 180 W: Complete motor protection with integrated electronic tripping system
• Connection to a 3-phase 230 V mains supply with optional switching plug

• Wilo TOP-S pump housing coated with cataphoretic varnish (KTL) for optimum corrosion protection
• Combination flange PN 6/PN 10 (for DN 40 – DN 65)
