Utilizing RitterPTEEHigh-performance composite diaphragm, with the diaphragm processed through multi-directional roller pressing and surface quenching, achieving uniformity to a high degree.99.92%, reduces cold flow during operation, enhances compressive strength;

Internally mounted safety and oil补给 valves, featuring automatic exhaust and oil replenishment, offering superior performance and reliability.

High-precision one-way valve sets are used for import and export, ensuring accurate measurement and flow efficiency.

Integrated“Eurode”Helical gear reducer transmission unit, low noise, high efficiency.

Patented integrated sleeve adjustable eccentric drive mechanism, simple and reliable, with stroke capability0—100％Continuous adjustment; Measuring accuracy±0.5％（10％-100％Adjustment Range）；

Oil immersed lubrication ensures long-term reliable operation of the transmission mechanism.

When transporting hazardous substances such as toxic, flammable, explosive, and highly corrosive materials, double or multi-membrane pumps can be used.

Fracture alarm device, to prevent accidents caused by medium contacting hydraulic oil when the diaphragm ruptures.

Multiple flow adjustment methods available, including manual, electric, pneumatic, and variable frequency control.

Equipped with an electric actuator, it can achieve remote automatic control.

Can be connected in parallel at both ends or multiple ends, up to12Head; Multiple pump heads can be used to pump the same medium, reducing pulsation; or can pump various media, serving as a metering pump.

Wide application range; capable of safely transporting various media.
