HAOSH offers a range of high-quality solenoid driven metering pumps suitable for accurate dosing of chemicals across various water and wastewater treatment applications. Their electromagnetic metering pumps provide flow rates from 0.4 L/H up to 80 L/H and can handle back pressures between 1.5-16 bar.

Simple and Reliable Design

HAOSH solenoid driven metering pumps feature a straightforward design with only one moving part - the solenoid. This minimizes wear and tear, resulting in extremely low maintenance requirements. Without any need for lubricated bearings or shafts, repairs and servicing costs are negligible. The pumps offer reliable continuous operation even in demanding conditions.

Customizable Flow Rates and Pressures

Depending on your flow and pressure needs, HAOSH provides three models of solenoid driven metering pumps - H, HS, and HH. You can select the model best suited for your specific application. Additionally, the electronic pulse control allows micro-adjustment of stroke length and frequency. This precise control enables customizable dosing rates from the pump.

Proven Performance in Water Treatment

For over 15 years, HAOSH solenoid driven metering pumps have been trusted in drinking water, wastewater, cooling towers and various industrial liquid handling applications. They are extremely effective at dosing small volumes of chemicals like disinfectants, flocculants, corrosion inhibitors and more. Thanks to their chemical resistance and robustness, HAOSH pumps ensure reliable and accurate dosing year after year.
