Product Overview
Process water reticulation and heavy industrial chemical transfer requiring three-phase power call for the robust mechanical design of the DMX 221 series. 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.
Powered 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.
The 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.
Construction 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.
FEATURES
- Three-phase 0.09 kW motor for sustained mechanical duty in industrial power supplies.
- Manual stroke length control via scale knob for reliable 10:1 turn-down adjustment.
- Mechanical diaphragm design with NBR/PTFE coating for industrial durability.
- PVC dosing head and EPDM gaskets for standard process chemical resistance.
- Double ball valve configuration for consistent hydraulic behaviour and backflow prevention.
- IP65 rated aluminium gear enclosure for demanding site conditions.
- G5/8 connections with cap and inserts for multiple site hose and pipe sizes.
- Set-and-forget manual control without complex electronic integration.
