Detail Information
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.

I graduated with a degree in Mechanical Design and began my career in 2012 as a QC engineer in the workshop. I worked my way up through CAD engineering and eventually served as Chief Technical Engineer. I joined Shinjo Co in 2016 and have since focused on control valves and a wide range of challenging process conditions, supporting numerous overseas clients with demanding applications.
Over the years, I have come to believe that quality and solution capability are what ultimately maximize value — for both the client and the company. We welcome complex and unconventional cases. I hope my industry experience can be of help to you.
