The Dayuan A1-Z-YC PM VFD Automatic Self-Priming Pump delivers efficient, economical, quiet yet powerful performance with strong driving force, high energy efficiency, ultra-low running noise and stable constant water pressure supply for whole-house smart water boosting.
Equipped with a premium PM motor that reaches a rotation speed of up to 3800r/min, it boosts efficiency by 8% and saves around 30% power compared with asynchronous pumps.
Fitted with heat-resistant sealing components, the pump supports both cold and hot water circulation and withstands liquid temperatures up to 100°C.
Its pump body adopts full dual-sided E-coating technology to realize dual-layer protection against corrosion and wear.
Built with an integrated temperature-pressure sensor and VFD intelligent control system, it maintains steady constant-pressure water outflow even when multiple water outlets including kitchen taps, wash basins, shower rooms and laundry equipment are used simultaneously.
Featuring a wide 165V–280V operating voltage range, it keeps stable water pressure output during peak electricity consumption periods.
Besides, it comes with 10 intelligent all-round safety safeguards working 24/7, covering overvoltage, undervoltage, overcurrent, phase loss, locked rotor, overtemperature, low temperature, water shortage, light load and leakage protection for comprehensive safe operation.
