Snowate Цифровой Дозирующий насос с регулируемой скоростью всасывания

The Snowate digital metering pump is a compact, volumetric diaphragm dosing pump equipped with a brushless DC motor (BLDC) and an intelligent electronic control system, achieving minimal energy consumption with up to 90% efficiency. By utilizing a helical gear and auxiliary spring design, it reduces energy consumption by 70% compared to traditional rebound mechanisms. The Snowate digital metering pump employs FOC closed-loop control and always operates at full stroke to ensure optimal dosing accuracy, priming capability, and suction performance. Based on the set flow rate, the duration of each discharge stroke is automatically adjusted to achieve smooth, continuous, and optimal output flow.

EX-B Series

Operation history: The controller records the total power connection time, operating time, number of strokes and the number of power switches.
Highly integrated cost saving: Highly integrated, cost saving, save the installation site, rich control interface, can avoid the traditional frequency conversion motor, frequency converter and complex PLC system.
Adjustable speed: When delivering viscous liquids, the suction stroke speed can be changed to avoid cavitation. (Programmable suction speed: 75%, 50% or 25% of normal speed)
Automatic exhaust function (optional): Exhaust can be performed by running the pump at maximum stroke rate in any mode, either through a key operation or signal contact(AUX).
Maintenance mode: The diaphragm can be moved forward to facilitate diaphragm replacement.
