Product Overview
Bulk chemical dosing and high-capacity industrial transfer requiring a side-mounted control interface define the role of this specialised configuration in the DME series. This system is engineered for industrial users who need to move up to 940 litres per hour where specific installation layouts require the side-mounted control panel for better visibility.
Driven by a 240 W motor operating on 415v, 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 across a broad range of flow settings down to a 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 that high-volume chemical delivery corresponds to system requirements.
Structural durability is ensured by a rugged Polypropylene dosing head and durable EPDM gaskets paired with glass ball valves. The unit includes an integrated alarm relay, handles liquid temperatures up to 50°C, is housed in an IP65 enclosure, and is supplied with high-capacity threaded Rp 1 1/4" connections.
