MA Series Dosing Pumps
MOTOR-DRIVEN DOSING PUMP
The MA series dosing pump is a positive displacement piston dosing pump with mechanical drive. It is widely used in industrial and scientific sectors, such as petrochemical, chemical, food, pharmaceutical, paper, light industry, agriculture, environmental protection in water bodies, etc., and is responsible for measuring and adding various media during the process. Different pump head materials are available to handle various types of liquids. The standard configuration is PVC material; other materials available include 304, 316, and PVDF.
MA series dosing pumps can handle corrosive or non-corrosive liquids without solid particles within the temperature range of -15 °C to 60 °C and viscosity of 0.3 to 1000 cps. The nominal flow rate of the pump ranges from 10 to 1800 l/h, and the corresponding maximum outlet pressure ranges from 10 to 1 bar. The pump flow rate is adjusted by rotating the handwheel, and the adjustment can be made from 0 % to 100 % regardless of whether the pump is running or not.
Steady-state accuracy is ±1 % within the flow rate range of 30 % to 100 %. This is a dosing pump with a simple design, low power consumption, accurate measurement, and practicality. Various types of dosing pumps can be equipped with explosion-proof motors or variable frequency motors upon customer request.
- Non-hermetic design.
- Smooth flow rate adjustment in both operating and non-operating states.
- Specifically designed for handling aggressive liquids.
- Adjustable flow rate in both operating and non-operating states.
- Various material options for different applications.
- Compact modular design.
- Dosing accuracy of ±1 % within 10–100 % of nominal flow rate.
- Double-ball check valve for easy maintenance.
- Easy replacement of parts.
- Multi-layer diaphragm ensures longer service life.
