The ZB4-30 is a reliable foundational PM VFD Self-Priming Constant Pressure Pump for clean water applications. As a core model in the ZB series, it features a 400W rated power, 2 m³/h rated flow, and 18 m rated head, with a maximum flow of 4 m³/h and maximum head of 30 m. Its 5 m self-priming height simplifies water extraction, and it operates with water temperatures up to 60℃. With an IPX4 protection level, DN25 ports, and 2-stage impeller, it prioritizes ease of use and durability—ideal for users with basic, consistent water supply needs (e.g., urban flats, small offices).
Consistent flow & head: 2 m³/h rated flow meets the needs of a 4–5 person family, while 18 m head ensures steady pressure for daily use.
2-stage impeller: Reduces pressure fluctuations when using multiple water outlets (e.g., washing machine + tap).
No complex controls: Easy to operate for users without technical expertise, reducing setup time.
Long service life: Insulation Class F and robust motor design extend durability, lowering replacement costs.
DN25 standard ports: Fits most residential plumbing, no need for custom adapters.
Compact size: Installs in utility closets or small equipment rooms, saving space.
Solves municipal water pressure issues: Boosts tap water pressure for showers, dishwashing, and toilet use in urban apartments.
Non-intrusive: Works with existing pipelines without modifying the main water supply.
Supports 10–20 employee offices: Provides water for handwashing, cleaning, and pantry needs.
Quiet operation: Low noise levels avoid disrupting office work during operation.
Well water extraction: Draws water from 5 m depths for drinking, cooking, and gardening.
Dust-resistant: IPX4 protection handles rural outdoor conditions, suitable for installation near wells.

Q: What maintenance does the ZB4-30 require?
A: 1) Clean the inlet filter monthly to prevent impurity blockages; 2) Avoid dry operation (stops motor damage); 3) Check wiring annually for wear. With proper care, it lasts 5–8 years.
Q: Can it circulate solar-heated water?
A: Yes—its 60℃ temp limit works with solar water systems. Ensure the water’s pH and impurity levels meet the pump’s requirements.
Q: Why won’t the pump self-prime?
A: Check three things: 1) Inlet pipes for leaks (air leaks break self-priming); 2) Inlet filter for clogs (clean if needed); 3) First-use water fill (subsequent uses don’t need pre-filling if pipes are sealed).
