Product Overview
Handling highly aggressive media at high volumes in water treatment and large scale industrial plants requires the increased hydraulic capacity of this PVDF configuration. This DME AR unit is intended for users who need to move up to 940 litres per hour with the maximum possible material compatibility to ensure consistent dosing accuracy in heavy industrial service.
The system is driven by a 240 W motor operating on 240v, delivering a maximum dosing capacity of 940 L/h at a 4 bar maximum operating pressure. It achieves an 800:1 turn-down ratio, enabling the system to precisely scale down to a minimum flow of 1.18 L/h without losing the accuracy of the volumetric output during bulk transfer duties.
The electronically controlled motor with variable stroke speed provides smooth and continuous dosing with reduced pulsation across the operating range. The inclusion of a diaphragm leak detector and chemical pre-empty and empty level inputs prevents process interruptions, while the potential-free output relays provide immediate signalling for system alarms.
Mechanical integrity is provided by a chemically resistant PVDF pump head and durable FKM gaskets paired with glass ball valves suitable for aggressive media. The unit includes integrated connectivity for process integration, is housed in a robust IP65 enclosure, and handles liquid temperatures up to 45°C (PVDF).
