    Automated industrial chemical dosing requiring high dosing capacity defines the role of this peak-capacity DME configuration in the industrial series. This system is engineered for industrial users who need to move up to 940 litres per hour of process chemicals with digital speed control and integrated system feedback to support reliable operation.

    Powered by a 240 W single-phase motor, the unit produces a maximum dosing capacity of 940 L/h at a 4 bar maximum operating pressure. It utilises an 800:1 turn-down ratio, which provides consistent volumetric accuracy from its peak flow rate down to a precise minimum of 1.18 L/h to match site specific chemical needs at large scale.

    The electronically controlled motor with variable stroke speed produces smooth and continuous dosing with reduced pulsation. This model incorporates integrated diaphragm leak detection and AR control functionality for manual, pulse, and analog modes, ensuring chemical delivery corresponds to the available system demands.

    Structural integrity is ensured by a rugged Polypropylene dosing head and durable FKM gaskets paired with glass ball valves. Connectivity is enhanced with an integrated alarm relay and inputs for low-level chemical signals. Housed in an IP65 enclosure, the unit handles liquid temperatures up to 50°C and includes high-capacity Rp 1 1/4" threaded ports.
