Product Features
- Intelligent fully‑automatic control Equipped with a flow switch, pressure sensor and digital display control panel. It collects real‑time water flow and pressure data to automatically start and stop the pump. The pump starts when the tap is opened and stops when the tap is closed, with no manual operation required. It supports delayed start‑up and pressure sensing for stable and smooth water output.
- Multiple safety protections Built‑in dry‑run protection automatically shuts down the pump in case of water shortage to prevent motor burnout. The anti‑scale function reduces limescale accumulation inside the pump and extends service life. It mitigates motor damage risks when voltage deviation exceeds 10% of the rated value.
- Durable core components High‑quality mechanical seal provides excellent leak‑proof performance. Copper‑alloy impeller delivers high strength, corrosion resistance and reliable flow capacity for long‑term wear‑resistant operation.
- Compact and space‑saving structure Small overall footprint with a stable base. Easy to install, move and operate, suitable for both household and light‑commercial applications.
- Powerful self‑priming performance Maximum suction lift reaches 8 m, no repeated refilling of priming water is needed. Maximum working pressure: 5 bar. It can handle liquid temperature up to 90℃ and ambient temperature up to 40℃.
Application Scenarios
- Groundwater intake: drawing well water and shallow underground water for rural self‑built houses.
- Water heater boosting: improving insufficient inlet pressure for water heaters and enhancing shower flow performance.
- Water supply pressurization for villas: whole‑house pressure boosting and stabilizing for villas and private residences.
- Municipal tap‑water boosting: solving weak tap‑water flow caused by low municipal pipeline pressure.
- Pressurization for high‑rise buildings: secondary pipeline pressurization for mid‑rise and high‑rise apartments to compensate insufficient water pressure on upper floors.
Daily Maintenance
- Inspect inlet/outlet pipes and joints monthly for water seepage or air leakage. Check sealing rings and mechanical seals for dripping. Air leakage will directly degrade self‑priming capacity.
- Remove limescale from pump chamber periodically. Install a pre‑filter for poor‑quality water to avoid impeller blockage, which would reduce flow rate and pressure.
- Keep the motor housing clean and well‑ventilated, free of dust buildup. Check power cables regularly for aging or damage.
- Drain all water inside the pump for long‑term storage to avoid pump cracking from freezing. Store the unit in a dry location.
- Calibrate pressure sensors and control panel every six months to ensure correct start‑stop pressure and accurate digital readings.
Usage Notes
- Medium requirements: Only for clean water or water‑like fluids. Do NOT pump liquid containing large amounts of sediment, sand or corrosive chemicals, as solid particles will rapidly wear the impeller and seals.
- Power supply: Voltage fluctuation shall not exceed ±10 % of rated voltage. A voltage stabilizer is recommended under unstable power supply to avoid damage to the electronic control board.
- Temperature limits: Max. pumped liquid temperature: 90℃; Max. ambient working temperature: 40℃. High temperature accelerates motor aging.
- Avoid frequent dry‑running: Although dry‑run protection is integrated, repeated dry‑run events will shorten the service life of mechanical seals. Always fill priming water before first startup.
- Installation requirements: Mount the pump horizontally. Minimize elbows in piping to reduce flow resistance. The suction pipeline must be fully air‑tight; air leaks will cause failure to draw water.
- Electrical safety: Reliable earthing is mandatory. Protect the electronic control panel from splashing water, take waterproof measures in humid environments.
- Pressure limit: System working pressure must not exceed 5 bar to prevent damage to pump body and connected pipes.
