This configuration is intended for properties and plants with industrial electrical infrastructure where maintaining a dependable chemical dosing rate is the primary service requirement for large-scale networks.\u003c\/p\u003e \u003cp\u003ePowered by a 0.09 kW three-phase motor operating on 415v, the pump achieves a maximum dosing capacity of 16 L\/h at a 12 bar maximum operating pressure. It utilises a 10:1 turn-down range, enabling the system to precisely adjust performance via manual stroke length control to match available chemical demand.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly utilises a rugged mechanical diaphragm and ceramic ball valves to produce a smooth, low-pulsation dosing profile during industrial service. The set-and-forget manual control focus ensures consistent performance across site networks without the need for complex electronic signal integration in standard duty cycles.\u003c\/p\u003e \u003cp\u003eConstruction features include a rugged PVC dosing head and EPDM gaskets paired with durable ceramic valves. Protection is maintained by an IP65 rated gear enclosure, the unit handles liquid temperatures up to 40°C, and is supplied with standard G5\/8 connections for easy installation across diverse site pipework infrastructure.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eThree-phase 0.09 kW motor for sustained mechanical duty in industrial power supplies.\u003c\/li\u003e \u003cli\u003eManual stroke length control via scale knob for reliable 10:1 turn-down adjustment.\u003c\/li\u003e \u003cli\u003eMechanical diaphragm design with NBR\/PTFE coating for industrial durability.\u003c\/li\u003e \u003cli\u003ePVC dosing head and EPDM gaskets for standard process chemical resistance.\u003c\/li\u003e \u003cli\u003eDouble ball valve configuration for consistent hydraulic behaviour and backflow prevention.\u003c\/li\u003e \u003cli\u003eIP65 rated aluminium gear enclosure for demanding site conditions.\u003c\/li\u003e \u003cli\u003eG5\/8 connections with cap and inserts for multiple site hose and pipe sizes.\u003c\/li\u003e \u003cli\u003eSet-and-forget manual control without complex electronic integration.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974842716407,"sku":"99205971","price":2148.52,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dmx-16-12-three-phase-mechanical-diaphragm-dosing-pump-chemical-dosing.png?v=1785154000","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dmx-16-12-three-phase-mechanical-diaphragm-dosing-pump-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
