The Hydro-Air MX-B series are diaphragm metering pumps that utilize stepper motors. They feature a high regulation ratio and highly integrated automatic control functions. In this design, the flow rate is precisely controlled by the rotation of the stepper motor. The motor's rotational motion is transmitted to an eccentric cam via reduction gears, where it is converted into reciprocating motion. This reciprocating action drives the diaphragm back and forth, causing periodic changes in the pump chamber volume. Liquid is subsequently drawn in and discharged through check valves. While the reciprocating speed determines the overall flow rate, the suction rate remains constant under all flow conditions. • High Turndown Ratio (1:1000) Equipped with a stepper motor and highly integrated industrial electronic controls, it enables precise control and feedback, achieving an exceptional turndown ratio of 1:1000. • High-Precision Dosing Independently controlled discharge speed ensures high chemical dosing repeatability (±1%). • High Integration Compact design with high integration for installation-friendly operation. • Automatic Control The EX-B can be configured to operate automatically via analog, pulse, or RS485 signals. • Wide Voltage Operation The EX-B series features a wide input voltage range (Standard: DC100-380V / AC85-260V; Optional: DC24V), making it suitable for use in all countries and regions. • Rich Signal Interface (Standard) Standard equipped with pulse signal input, current signal input, current signal output, STOP, Emergency Stop, Alarm, and RS485 communication interfaces to meet diverse and complex application requirements. • User-Friendly Design with LED Indicators The visual display screen allows for clear and intuitive monitoring of the dosing rate. LED indicators on the control unit clearly show various operating statuses and alarm conditions. • Standard PVDF Pump Head Features excellent corrosion resistance, outstanding temperature resistance, and superior physical properties. It offers exceptional resistance to strong acids and organic solvents, with a long-term operating temperature of up to 100°C. The material is high-strength, wear-resistant, and aging-resistant. • Overpressure Alarm Function If the discharge pressure exceeds the pump's operating pressure, the metering pump will automatically stop and trigger an alarm, preventing pump damage due to overpressure. • IP65 Protection Rating With an IP65-rated enclosure for dust and water resistance, it is suitable for harsh operating environments. • Low Pulsation Output Features a "fast suction, slow discharge" low-pulsation design. By leveraging precise motor control for dosing, it represents an innovation in metering pump technology, ushering in a new era of intelligent dosing.
