| PM VFD Self-Priming Constant Pressure Pump | ZB4-30-M2 | 350 W | 2 m³/h | 20 m | 4 m³/h | 30 m | 220 V | 2.9 A | 2 | 2500～5600r/min | DN25 | F | 50Hz/60Hz | IPX4 | 5 m | ≤60 ℃ |
The ZB4-30-M2 is an energy-optimized PM VFD Self-Priming Constant Pressure Pump designed for clean water scenarios. With a lower rated power of 350W (vs. similar models), it maintains a rated flow of 2 m³/h while boosting the rated head to 20 m—perfect for users needing slightly higher pressure without sacrificing efficiency. It supports a maximum flow of 4 m³/h, maximum head of 30 m, and 5 m self-priming height, operating safely with water temperatures up to 60℃. Equipped with a 2-stage impeller, DN25 ports, and IPX4 protection, it balances cost-effectiveness and performance for residential, rural, and small commercial settings.
350W low-power design: Cuts electricity use for long-term operation (e.g., 24/7 tap water pressurization) compared to 400W models.
Smart speed regulation: PM VFD technology adapts to demand—slows down during low-use hours (e.g., nighttime) to save energy.
20 m rated head: Delivers stable pressure to 2–3 floor duplexes or rural houses, avoiding weak flow in upper floors.
Consistent performance: Maintains pressure even when multiple taps (e.g., shower + kitchen) are used simultaneously.
No pre-filling needed: Self-priming function simplifies well water extraction or roof tank connection.
Low maintenance: Insulation Class F and corrosion-resistant components reduce wear, minimizing repair needs.
Duplex apartments: Resolves low pressure in upper floors, ensuring strong flow for bathing, dishwashing, and toilet flushing.
Rural multi-story homes: Pressurizes well water to reach all floors, supporting daily domestic needs.
Bath clubs & guesthouses: Circulates hot water (≤60℃) to maintain consistent temperatures, reducing wait times for users.
Air energy systems: Works with air energy heaters to circulate water, improving heat efficiency.
Extracts well water from 5 m depths: Provides continuous clean water for drinking, gardening, and livestock care.
Weather-resistant: IPX4 protection handles rural dust and minor splashes, suitable for semi-outdoor installation.

Q: How does the ZB4-30-M2 differ from the ZB4-30-M?
A: Key differences are power and head: The ZB4-30-M2 uses 350W (more energy-saving) and has a 20 m rated head (higher pressure), while the ZB4-30-M uses 400W and 18 m rated head. Both share max flow, self-priming height, and IPX4 protection.
Q: Can it be used for under-floor heating?
A: Yes—its 60℃ water temp limit and stable flow make it compatible with under-floor heating systems. Ensure the system’s water meets impurity (≤0.1% solids) and pH (6.5–8.5) requirements.
Q: What power frequency does it support?
A: It works with both 50Hz and 60Hz power supplies, making it suitable for regions with different electrical standards (e.g., Asia, Europe, North America).
