The PBG4-30X is a specialized PM VFD Constant Pressure Pump for clean water applications, focusing on stable pressure control (not self-priming). With a 350W rated power, it delivers a rated flow of 2.2 m³/h and 20 m rated head, supporting a maximum flow of 4 m³/h and 30 m maximum head. A key distinction is its 50℃ water temperature limit—optimized for cool water scenarios like equipment cooling or solar systems. It features a 2-stage impeller, DN25 ports, and IPX4 protection, making it ideal for residential, light industrial, and small commercial use where pre-filling is feasible.
PM VFD technology: Maintains consistent pressure regardless of demand, preventing noisy pipes or appliance performance issues (e.g., dishwashers).
Smooth flow adjustment: Avoids sudden pressure spikes that damage plumbing.
50℃ temp limit: Safe for industrial equipment cooling or solar systems with moderate water temperatures, protecting internal seals from overheating.
Steady performance: Operates reliably in cool water cycles (e.g., 24/7 equipment cooling).
350W low-power design: Saves energy for continuous use.
Quiet operation: Suitable for indoor installation near living or working areas (e.g., office equipment rooms).
Cools small machinery: Circulates ≤50℃ water to cool laser printers, small motors, or electronic components, reducing overheating downtime.
Stable flow: Ensures consistent cooling, improving equipment efficiency.
Works with solar heaters: Circulates moderate-temperature water (≤50℃) between collectors and storage tanks, maximizing solar energy use.
Constant pressure: Reduces heat loss by maintaining steady water flow.
Supplies water for spas or small bath clubs: Delivers stable pressure to showers and handwashing stations.
Damp-resistant: IPX4 protection handles splashes in humid environments.

Q: Why is the water temp limit 50℃ instead of 60℃?
A: The PBG4-30X is optimized for cool water applications (e.g., equipment cooling). Its seals and motor components are designed for ≤50℃ to ensure long-term reliability. For high-temp needs, choose ZB series models.
Q: Is the PBG4-30X self-priming?
A: No—it requires pre-filled inlet pipes and positive inlet pressure. It’s best for systems with existing water pressure (e.g., municipal supply, bottom-fed tanks).
Q: What wire gauge should I use for installation?
A: Its rated current is 2.6 A, so use 1.5 mm² or thicker copper wire. Equip a ≥5 A circuit breaker to prevent overload, and verify the 220V rated voltage matches your supply.
