2. Pressure range: Pmax = 1.2MPa;

3. Standard configuration: Materials include PVC, PVDF/PTFE, 304/316L; power supply 380V/50Hz;

4. Optional configuration: Single-phase motor; pump head material and inlet/outlet connection can be customized.

Key Features & Advantages
Superior Corrosion Resistance: Equipped with a high-strength PTFE (Polytetrafluoroethylene) diaphragm, the GM series is designed for longevity and is capable of handling the most aggressive and dangerous liquids without degradation.
Vertical Drive Design: The motor is positioned vertically above the transmission box. This innovative layout prevents lubricant leakage and significantly enhances transmission reliability.
High-Accuracy Check Valves: Utilizes a high-precision one-way check valve structure. This ensures meticulous metering accuracy, excellent sealing properties, and low maintenance costs through interchangeable parts.
Simplified Maintenance: The transmission mechanism is oil-lubricated, requiring only periodic oil changes. The system is designed for "set and forget" reliability without the need for specialized maintenance teams.
Versatile Material Options: To match your specific fluid requirements, the liquid-end components are available in PVC, PVDF, PTFE, and SS304/SS316. Custom materials are available for specialized industrial applications.
