Fatek SDM Series dosing pumps are among the most widely used and best-selling solenoid diaphragm dosing pumps for water treatment, swimming pools, chemical applications, and industrial processes. Equipped with a precise solenoid-driven mechanism, this series enables controlled dosing of various chemicals. Thanks to its simple design, high durability, and easy maintenance, it has become a popular choice for both industrial and semi-industrial projects.

The SDM Series is designed for dosing a wide range of chemicals, including sodium hypochlorite, antiscalants, acids, alkalis, coagulant polymers, ferric chloride, PAC, and other chemicals commonly used in water treatment systems and process lines. The availability of different material options for the pump head, diaphragm, check valves, and other wetted parts also makes this series suitable for a broad range of applications and operating conditions.

Precise flow control, adjustable dosing capacity, stable performance during continuous operation, and a wide selection of models with different pressure and flow ratings allow SDM dosing pumps to meet the requirements of many industries. Below, you can explore the available models in this series and select the most suitable option for your project based on the type of fluid, operating pressure, and required dosing capacity.
