ΆΓ JMHN series are the hydraulic diaphragm
metering pump with a built-in air chamber,
which shows excellent microseism prevention,
no vibration and noise, and high precision
injection is possible. Especially, as relief
valve is built-in, if over pressure occurs,
it discharges pressure automatically, so
pump and system can be protected safely.
- A pump with a built-in air chamber
- An injection accuracy is high, and there's
no vibration or noise
- Enhanced durability
- Relief valve built-in
- Adoption of the IEC motor standard
