Product Overview
The GM Series Mechanical Diaphragm Metering Pump is engineered for precision and durability in demanding chemical injection tasks. Featuring a unique vertical motor configuration and a high-strength PTFE diaphragm, this series provides a leak-free, reliable solution for transporting hazardous and corrosive fluids. It combines compact structural design with industrial-grade performance, making it a staple for water treatment and chemical processing.
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.
