| PM VFD Self-Priming Constant Pressure Pump | ZB | ZB4-30-S | 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-S is a star model in the ZB series, a PM VFD (Permanent Magnet Variable Frequency) Self-Priming Constant Pressure Pump designed exclusively for clean water scenarios. With a 350W power rating, it delivers a 2 m³/h rated flow and 20 m rated head—plus a maximum flow of 4 m³/h and maximum head of 30 m to handle sudden water demand spikes (e.g., simultaneous shower and dishwasher use). It operates on 220V voltage (2.9A rated current), features a 2-stage impeller for stable pressure, and supports a speed range of 2500～5600 r/min for flexible adjustment.
A key differentiator is its 5m self-priming height—eliminating the need to pre-fill pipes with water before use—and it tolerates water temperatures up to 60℃, making it suitable for both cold and moderate hot water systems. The pump also meets strict safety standards: DN25 inlet/outlet size for easy piping, insulation class F (resists overheating), and IPX4 protection (shields from splashing water), while handling clean water with ≤0.1% solid impurities (particle size ≤0.2mm).
The ZB4-30-S solves two common pain points: inconsistent water pressure in multi-story homes and the hassle of priming traditional pumps. It balances efficiency, convenience, and durability, making it a go-to for residential and small commercial clean water needs.
As a PM VFD pump, it cuts energy consumption by 30%～50% compared to fixed-speed pumps. Its variable frequency technology automatically adjusts motor speed based on demand: slows down when only one tap is in use (reduces electricity costs) and ramps up for peak hours (e.g., morning rush for showers). This also reduces wear on internal parts, extending the pump’s lifespan.
For users relying on well water or roof tanks (where the water source is below the pump), the 5m self-priming function simplifies installation and daily use. No more manual water filling—just switch on the pump, and it draws water directly from the source.
It supports both 50Hz and 60Hz frequencies, fitting power systems in regions like Asia, Europe, and North America. The 2-stage impeller is built for long-term use, while insulation class F and IPX4 protection ensure safe operation in damp environments (e.g., garages, basements, or near water heaters).
• Villas & Duplexes: Maintains stable pressure across multiple floors, ensuring consistent flow for taps, showers, and appliances (e.g., washing machines) even when used simultaneously.
• Rural Homes: Ideal for well water extraction (thanks to 5m self-priming) and boosts pressure for roof tank supply, resolving low-flow issues in remote areas.
• Flat Houses: Enhances municipal tap water pressure, fixing weak flow in older buildings or areas with poor water infrastructure.
• Under Floor Heating: Circulates water (≤60℃) to maintain even room temperatures, leveraging variable speed to match heating demand and save energy.
• Solar/Air Energy Systems: Transfers water between solar panels/air-source heat pumps and tanks, ensuring efficient heat exchange with its stable flow.
• Small Offices: Supplies clean water to restrooms and pantries, with low noise operation (a PM VFD advantage) that doesn’t disrupt workspaces.

Its 5m self-priming height is critical—it can draw water from wells up to 5m deep without pre-filling. Additionally, its tolerance for ≤0.1% solid impurities aligns with typical well water quality, preventing clogs or impeller damage.
Beyond 30%～50% energy savings, it offers: (1) intelligent speed regulation (no manual pressure adjustments), (2) lower noise (quieter than fixed-speed pumps), (3) longer lifespan (reduced motor strain), and (4) self-priming convenience (saves time on setup).
• Secure the pump to a flat, stable foundation to minimize vibration (avoids noise and mechanical wear).
• Install an inlet filter to trap impurities >0.2mm—this protects the 2-stage impeller.
• Keep the motor shaft horizontal during installation (misalignment causes premature failure).
• Verify the power supply is 220V before wiring—mismatched voltage damages the motor.
