| PM VFD Self-Priming Constant Pressure Pump | ZB | ZB6-55 | 900 W | 4 m³/h | 30 m | 6 m³/h | 55 m | 220 V | 5.5 A | 3 | 1000~4600r/min | DN25 | F | 50Hz/60Hz | IPX4 | 5 m | ≤60 ℃ |
The ZB6-55 PM VFD Self-Priming Constant Pressure Pump is a high-power model from the ZB series, built for scenarios with large water demand (e.g., big villas, small commercial buildings). With 900 W power and 4 m³/h rated flow, it outperforms smaller self-priming pumps (e.g., ZB5-45) while retaining the convenience of self-priming. It’s designed for clean water—water temperature ≤60℃, pH 6.5–8.5, and solid impurities ≤0.1% (particle size ≤0.2mm)—making it a versatile choice for residential and light commercial use.
Power: 900 W (high-power for heavy-duty use)
Rated Flow: 4 m³/h; Maximum Flow: 6 m³/h
Rated Head: 30 m; Maximum Head: 55 m
Self-Priming Height: 5 m (same as ZB5-45, but with higher flow)
Electrical/Structural: 220 V, 5.5 A, 3-stage impeller, 1000–4600 r/min speed range, DN25 inlet/outlet, F-class insulation, IPX4 protection
The 900 W motor delivers 4 m³/h rated flow (6 m³/h maximum)—enough to supply a 5–6 bedroom villa with 8–10 people, plus a swimming pool or garden irrigation system. For example, it can fill a 10,000L swimming pool in ~34 hours (vs. 50+ hours for a 600 W pump), saving time for homeowners.
With 30 m rated head and 55 m maximum head, the ZB6-55 handles tall buildings (4–5 stories) and long pipe runs (e.g., 50+ meters from well to home). It’s also suitable for water tower supply—boosting water from ground tanks to rooftop towers, even with multiple bends in the pipe.
Thanks to PM VFD technology, the pump doesn’t waste energy on constant high-speed operation. For example, during low-demand hours (e.g., midday when everyone is out), it reduces speed to 1000–2000 r/min (using ~300 W), while ramping up to 4600 r/min (900 W) during peak hours. This keeps energy bills low despite its high power.
Big villas often have multiple bathrooms, kitchens, swimming pools, and gardens. The ZB6-55 supplies water to all these areas simultaneously: it boosts tap pressure for showers/ sinks, fills the pool efficiently, and irrigates large gardens (6 m³/h flow covers 1000+ square meters of lawn).
For office buildings with 20–30 employees or hotels with 10–15 rooms, the pump provides reliable water for restrooms, pantry sinks, and cleaning services. Its 55 m maximum head ensures water reaches upper floors (4–5 stories), while the constant pressure feature prevents flow drops when multiple toilets/faucets are used.
Small factories (e.g., metalworking or printing) use cooling towers to regulate machinery temperature. The ZB6-55 circulates water between the tower and machinery—its 6 m³/h flow keeps the tower filled, and the ≤60℃ temperature limit matches cooling water requirements (avoiding overheating of pumps or machinery).
