MG Series Metering Pumps
METERING PUMP WITH ELECTRIC MOTOR DRIVE
The MG series metering pump is a positive displacement piston pump with mechanical drive. It is widely used in the oil, chemical, food, pharmaceutical, paper, light industries, agriculture, water supply stations, and other industrial and technological sectors for handling all types of media in measurement and dosing processes. Depending on the media, various materials are available, including PVC, SS304, SS316, PTFE, and others.
MG series metering pumps can handle liquids with temperatures ranging from -15 ℃ to 60 ℃ and viscosity from 0.3 to 1000 cps, including corrosive or non-corrosive liquids without solid particles. The nominal flow rate of the pump is 15–130 l/h, with a corresponding maximum discharge pressure of 10–4 bar. The pump flow can be adjusted using a handwheel from 0 % to 100 %, regardless of whether the pump is running or not.
In the range from 30 % to 100 % of flow, the steady-state accuracy is ±1 %. This is a simple design, low-power consumption, accurate measurement practical metering pump. Various models can be configured to meet 220 V, 380 V or other motor voltage requirements. Technical specifications and parameters of the pump models are provided in the company’s brochures.
- Hermetic design.
- Smooth flow adjustment in both operating and non-operating states.
- Specifically designed for handling aggressive liquids.
- Adjustable flow 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.
- Double ball check valve for easy maintenance.
- Easy replacement of parts.
- Multi-layer diaphragm ensures longer service life.
