Applicability boundaries
Suitable for
Pure water production lines for clean raw water (tap water/ground water/clean water pool), beverage production water, CIP pre-pressurization, and unstable water pressure.
Working Principle
Utilizing a vertical or horizontal multistage centrifugal pump, the motor drives the impeller to rotate at high speed; centrifugal force creates negative pressure to draw in water, while multistage pressurization transforms low-pressure raw water into a stable, high-pressure flow. Equipped with pressure protection components, the system ensures constant-pressure water supply and provides safeguards against dry running due to water shortage, as well as automatic start/stop protection.
Core components
Motor
Pure copper windings; ensures stable continuous operation, high-temperature resistance, and durability against burnout.
Multi-stage impeller/pump chamber
Core pressurization assembly that determines the equipment's flow rate and head.
Pressure protection components
Pressure gauge and pressure switch; provide stable pressure regulation as well as overload and dry-run protection.
Optional
01
Variable-frequency control: Adaptive voltage stabilization
02
Energy saving and noise reduction: Eliminates pressure fluctuations
03
Intelligent alarm module: Automatic alerts and data transmission for water shortage, overload, and leakage
Changeover/Cleaning/Maintenance
Cleaning &Inspection
Clean the pre-filter weekly; inspect the mechanical seal, wiring, bolts, and vibration-damping structure monthly; and calibrate pressure parameters for variable-frequency models.
Replacement of wear parts
Replace the mechanical seal every 6–12 months; replenish bearing grease annually and replace it every two years; clean scale and debris from the impeller quarterly; match pump body parameters according to capacity upgrade requirements.
Frequent starts, stops, and trips?
Water shortage, dry burning, pressure switch failure, pipeline blockage, motor overload, check the water source, pipeline, and circuit protection one by one.
Can the pre-filter be removed?
Demolition is prohibited. Impurities will quickly wear the impeller and break down the mechanical seal, directly shortening the life of the water pump and causing the pump body to be scrapped.
How to choose between frequency conversion and fixed speed?
For stable and small production capacity, choose speed (high cost performance); for large fluctuations in water use, choose frequency conversion for constant pressure and energy saving.
