Product Overview
Industrial chemical reticulation requiring enhanced material resistance from a mechanical diaphragm system are served by this robust configuration. This DMX 221 system is intended for rural and industrial users who need a dependable solution with FKM gaskets for compatibility with diverse non-aggressive media.
The unit is driven by a 0.09 kW single-phase motor drawing power from a standard 240v supply to maintain high hydraulic efficiency. It delivers a maximum dosing capacity of 16 L/h at a 12 bar maximum operating pressure, utilising a 10:1 turn-down range through manual stroke length adjustment for consistent fluid management.
The hydraulic design utilises a robust mechanical diaphragm paired with ceramic double ball valves to ensure accurate fluid handling and long-term service. This basic control model supports manual adjustment via a 10-100% scale knob, ensuring that chemical delivery corresponds to the available site process requirements during daily duty.
Mechanical integrity is maintained by a PVC pump head and durable FKM gaskets paired with ceramic ball valves. The unit features an IP65 rated gear enclosure with aluminium construction, handles liquid temperatures up to 40°C, and is supplied with standard G5/8 connections for versatile site tubing and pipework.
