CORE ADVANTAGE


Intelligent Control · Scenario Adaptable

Compact integrated design saves installation space.With versatile control interfaces, it eliminates the needfor traditional variable-frequency motors, drives, flowmeters, and complex PLC systems-reducing bothinitial investment and operating costs.


Precision Intelligence · Flexible Adaptability

1. DC brushless motor drive delivers metering accuracy

of +1%.

2. Adjustable suction stroke speed - set to 25%/50%/75% of normal speed for viscous fluids to effectivelyprevent cavitation.

3. Smart flow calibration - simply input measuredvalues for automatic calibration, eliminating manualerrors and ensuring reliable flow accuracy.

4. Supports 4- 20 mA analog signal, passive pulsesignal, STOP signal, and RS485 communication, with4- 20 mA feedback.

5. Batch / interval batch operation - easy keypadprogramming enables timed, precise dosing, ideal forvarious cyclic dosing applications.


Energy Efficient · Stable Output

1. ECO operation - innovative helical gear + auxiliary spring structure reduces power consumption by 70%

compared to traditional return spring designs, delivering greater economy in long-term operation.

2. Low-pulsation stable output - adjustable discharge speed (with fixed suction speed) ensures stable output across the entire flow range; the low-pulsation design significantly reduces pipeline shock and system load.


Safety Protection · Reliable Durability

1. IP65 sealed drive & control unit - waterproof and dustproof.

2. AC200- 240V universal input; CE certified for global use.

3. Multi-intelligent alarms - overpressure, leakage, STOP, batch complete, interlock; automatic alarm + coordinated shutdown.

4. Optional Diaphragm rupture detection - instant alarm prevents leakage and damage.


Human-Centric Design · Easy Operation & Maintenance

1. 3.5" color LCD - clear display of flow & signal; green/yellow/red status indicators visible from a distance.

2. Multiple connections - hose, threaded, flange, union adapters available.

3. Easy maintenance - forward-access diaphragm for quick replacement.

4. Operation history - records totalized flow & power-on cycles for simplified management.

5. 12V DC output - powers auxiliary instruments directly.
