Description
The Chemical Dosing Pump Emec 5 L/h is an electromagnetic (solenoid) metering pump made in Italy by Emec, one of the brands we prefer for chemical dosing. It injects precise, adjustable amounts of liquid chemical into a water line, at up to around 5 litres per hour. Typical uses include chlorine dosing for disinfection, antiscalant dosing before RO membranes, pH correction, and corrosion inhibitor dosing for cooling and boiler systems.
Applications in Oman
- Sodium hypochlorite dosing for tanks, wells and building supplies
- Antiscalant dosing ahead of commercial RO plants
- Acid or caustic dosing for pH correction
- Chlorine and pH control for swimming pools
- Corrosion and scale inhibitor dosing for cooling towers and chillers
- Coagulant dosing in small treatment plants

How it works
An electromagnet drives a PTFE diaphragm back and forth. Each stroke draws chemical through the suction valve and pushes a fixed volume out through the delivery valve into the injection point. Output is adjusted by changing the stroke frequency, and on many models it can follow a water meter pulse or a 4–20 mA signal, so dosing rises and falls with flow.

Complete dosing systems
For a reliable installation, the Chemical Dosing Pump Emec is paired with a chemical tank, suction lance with level switch, injection valve and, where needed, a flow meter or controller. Farz Water designs and installs complete skids. See related products in our dosing systems range and water treatment chemicals. For background, see metering pump on Wikipedia.
Maintenance
Check the injection valve and foot valve every few months for blockage, and replace diaphragms and valve seals on a yearly schedule or as advised for your chemical. Flush with clean water before long shutdowns.
