GM mechanical diaphragm metering pump which is reliable pump require minimal maintenance with high performance. It has long-term cost benefits of low lifecycle cost. Double-diaphragm design is available for sensitive liquid dosing. Each pump with the reinforced plate to protect the diaphragm to increase the working life. Both stroke length and stroke speed can be adjusted to alter capacity.GM pump are very durable for chemicals dosing such as aluminum sulfate, polymers, alkalis, sodium hydroxide, acids, anti-scaling and anti-foaming agents ,chlorine and so on. It is widely used in waste treatment treatment, industrial chemical process, agriculture, and many more applications.
