The GM Series Oil-Free Diaphragm Vacuum Pumps are compact and reliable vacuum solutions designed for laboratory applications requiring clean, stable vacuum generation without oil contamination. These pumps use a diaphragm-based mechanism, eliminating the need for lubricating oil and ensuring contaminant-free operation, making them ideal for analytical laboratories, sample preparation workflows, filtration systems, and vacuum manifolds.
The pumps incorporate a built-in filtration system that ensures clean exhaust air, while the automatic cooling exhaust system enables continuous operation for extended laboratory workflows. The adjustable pressure design allows users to control vacuum levels and gas velocity to meet specific experimental requirements. Selected models also feature TEFLON surface treatment to enhance resistance against corrosive gases, making them suitable for chemically demanding applications.
GM Series pumps are widely used in laboratories for solid phase extraction (SPE), vacuum filtration, solvent evaporation, degassing, and vacuum drying, providing stable performance with low noise and minimal maintenance.
