Product Introduction
The ZW type self-priming pump is a centrifugal pump with self-priming function, suitable for conveying clear water, sewage, oil and liquids containing solid particles. This pump features strong self-priming capacity, compact structure and stable operation. It is widely used in municipal engineering, sewage treatment, agricultural irrigation, industrial circulating water and other fields. Its temperature range is from -20℃ to 80℃.
Model Description:
Take ZX65-30-15 as an example:
- ZX: ZX-type self-priming pump type
- 65: Pump inlet diameter (mm)
- 30: Pump rated flow (m3/h)
- 15: Pump rated head (m)

Product Features:
- Strong self-priming ability: The unique impeller design enables a self-priming height of up to 5 meters and a short self-priming time.
- Compact structure: With a reasonable design, it occupies a small area and is easy to install.
- High efficiency and energy saving: Advanced hydraulic models are adopted, ensuring high efficiency and low energy consumption.
- Smooth operation: The impeller undergoes precise balance correction, resulting in low vibration and low noise.
- Easy maintenance: The pump shaft and motor are on the same axis, making disassembly and assembly convenient and reducing maintenance costs.
- Reliable sealing: Mechanical seals or packing seals are used to ensure no leakage and reliable operation.

Scope of Application:
- Municipal engineering: for urban water supply, drainage and sewage treatment.
- Agricultural irrigation: for farmland irrigation and sprinkler systems.
- Industrial circulating water: for cooling systems, boiler feed water, condensate water transportation, etc.
- Sewage treatment: for transporting sewage containing solid particles, sludge, etc.
- Oil transportation: for transporting oil and oily liquids.
