DHW circulation pump Wilo Top-Z 80/10 DM

Hot water circulation pump Wilo Top-Z 80/10 DM

Wilo TOP-Z circulation pumps circulate water in heating, hot water and floor heating systems. Wilo TOP-Z 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 Wilo TOP-Z electronic high-efficiency pump saves up to 90% of energy compared to an unregulated circulation pump. If, however, the Wilo TOP-Z pump is used in the hot water supply system, then the energy savings compared to standard circulation pumps will be 80%.

Equipment and functions of Wilo TOP-Z circulation pumps:

• manual power adjustment with 3 speed settings
• Wilo pumps TOP - Z 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 pumps TOP - Z 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

• fault indicator
• contact for generalized fault signaling
• control indicator for direction of rotation
• connection to a 3-phase 230 V mains supply with optional switching plug
• Wilo pump housing TOP - Z bronze or gray cast iron (may be stainless steel depending on the type)
• combined flange PN 6/PN 10 (for DN 40 – DN 65)
• thermal insulation for use in heating systems
• Additional functions when retrofitting with protection module C:

• fault signaling SSM as potential-free NC contact;
• operation signaling SBM as potential-free normally open contact
• control input "Off" by priority" with an external potential-free contact (NC contact)
• blockage detection
• complete motor protection for the Wilo pump TOP - Z built-in disconnect device

• Wilo double pump control system (two pumps installed in parallel): Master/standby operating mode (automatic pump changeover on fault/timer)

Equipment and material of Wilo TOP-Z circulation pumps:

• for Wilo pumps TOP - Z with flange connection: Flange versions

• standard version for pumps DN 40 - DN 65: combination flange PN 6/10 (flange PN 16 according to EN 1092-2) for counter flanges PN 6 and PN 16,
• standard version for DN 80 pumps: flange PN 6 (designed PN 16 according to EN 1092-2) for counter flange PN 6,
• special version for pumps DN 40 - DN 80: flange PN 16 (according to EN 1092-2) for counter flange PN 16

• cable entry possible on both sides (only for single-phase and three-phase pumps with P ₂ ≥180 W)
• serial thermal insulation
• Wilo pump housing TOP - Z : stainless steel / bronze / gray cast iron (depending on type)
• impeller: synthetic material
• shaft: stainless steel/ceramic (depending on type)
• bearings: graphite impregnated with synthetic resin
