Key Features & Advantages
Superior Corrosion Resistance: Equipped with high-strength PTFE (Teflon) diaphragms, the GB series offers exceptional chemical compatibility and an extended service life for transporting dangerous liquids.
Precision Metering & Sealing: The high-precision one-way check valve structure ensures accurate dosing, compact assembly, and excellent sealing performance, reducing operational costs while maintaining high interchangeability.
Leak-Proof Structural Design: The motor is positioned vertically above the transmission box, effectively preventing lubricant leakage. This unique configuration enhances transmission reliability and simplifies maintenance.
Flexible Material Customization: Flow-end components are available in PVC, PVDF, PTFE, and SS304/SS316. We also provide custom materials for specific chemical profiles, ensuring suitability for both corrosive and non-corrosive media.
Low-Maintenance Drive: The oil-lubricated transmission system requires only periodic oil changes, eliminating the need for complex, specialized maintenance routines.
