Product Features

1. Built‑in self‑priming capability for flexible installation No foot valve is required. The maximum self‑priming suction height reaches up to 9 meters, enabling direct water intake from shallow wells and water tanks. Equipped with an integrated 2‑L pressure tank and pressure switch for fully automatic operation. The pump starts automatically on water demand and stops when water supply is cut off, with no manual intervention needed.
2. Low flow rate with high head Featuring vortex‑type construction, it delivers higher head than standard centrifugal pumps at equal power. Well‑suited for conditions requiring high water pressure with moderate water consumption. Compact overall dimensions save installation space, ideal for confined locations.
3. High‑quality core components Brass impeller provides excellent wear‑resistance and anti‑corrosion performance without water contamination. AISI 304 stainless‑steel pump shaft improves corrosion resistance and service life. Fitted with C&U bearings for low vibration and quiet operation.
4. Copper‑wound motor with thermal protection Pure‑copper motor windings generate less heat and ensure high efficiency. The single‑phase motor comes with a built‑in thermal protector that cuts off power automatically under overload, locked‑rotor or over‑temperature conditions to prevent motor burnout. Insulation class F, IPX4 protection rating against splashing water.
5. Anti‑rust treated pump body for broad working conditions Cast‑iron pump body and support receive special anti‑rust treatment for enhanced durability in humid environments. Maximum permissible liquid temperature: 60 °C; maximum ambient temperature: 40 °C; maximum system working pressure: 8 bar.

Application Scenarios

• Household tap‑water pressure boosting: Boost water pressure for showers and water heaters where municipal water supply pressure is insufficient.
• Shallow‑well water supply: Draw groundwater from shallow wells to supply domestic water for self‑built houses.
• Garden sprinkler and irrigation: Supply high‑pressure low‑flow water for garden sprinklers and atomized irrigation systems.
• Auxiliary water supply for equipment: Makeup water for boilers and small‑size central air‑conditioning units; supporting water supply for water purifiers and compact washing machines.
• Light‑duty commercial water supply: Unattended automatic water supply for small shops and villas.

Routine Maintenance

1. Regular pipeline sealing inspection Check inlet / outlet pipes and sealing gaskets monthly. Air leakage in suction piping will degrade self‑priming performance and cause failure to draw water. Replace aged gaskets promptly.
2. Protection against sediment and impurities Narrow flow passages inside the vortex impeller are sensitive to sediment. Install a filter on the suction side to avoid particle jamming the impeller, and clean the filter screen periodically.
3. Inspection for motor and pressure tank Keep the motor housing well‑ventilated and free of dust. Inspect power cables for damage. Check the 2‑L pressure tank, verify correct automatic start‑stop behaviour, and troubleshoot pre‑charge pressure if pressure output becomes abnormal.
4. Long‑term shutdown storage Drain all water inside pump cavity during long idle periods. Fully drain water under low‑temperature conditions to prevent frost cracking of cast‑iron pump housing. Store in dry and ventilated place.
5. Abnormal noise and bearing service Carry out annual inspection. Listen for friction noise during running. Replace bearings immediately when abnormal noise occurs to avoid pump‑shaft wear.

Usage Notes

1. Medium requirements Only for pumping clean fresh water. Do NOT pump sediment‑laden sewage, corrosive fluids or oily liquids. Fine sediment may jam impeller and burn out motor. Liquid temperature must not exceed 60 °C.
2. Dry‑running forbidden Fill pump chamber with priming water before first startup. Dry‑running without water is strictly prohibited, as it will rapidly damage the mechanical seal.
3. Power‑supply requirements Maintain operating voltage within ±10 % of rated value. When thermal protection shuts down the unit, allow natural motor cooling; do not force repeated power‑on.
4. Pressure limitation System working pressure shall never exceed 8 bar to avoid rupture of pump housing and piping.
5. Installation requirements Mount pump horizontally. Keep suction piping as short as possible and reduce elbows to minimize flow resistance. Suction pipeline must remain fully air‑tight; air leakage will disable self‑priming function.
6. Electrical safety Reliable earthing is mandatory. IPX4 rating only defends against splashing water. Never rinse motor and wiring components directly with water. Apply extra waterproof measures in humid locations.
7. Anti‑rust inspection Check outer‑surface rust of cast‑iron pump body for long‑term operation in humid environments. Apply supplementary anti‑rust treatment if necessary.
8. Working‑condition reminder This is a low‑flow high‑head self‑priming pump and is not suitable for large‑volume water delivery. Select standard centrifugal pump or jet pump for high‑flow demands.
