Diaphragm Vacuum Pump LMVP20 is a chemical-resistant oil-free vacuum pump designed for laboratory applications involving corrosive gases, solvent vapors, and chemical processing environments. The pump features a two-stage diaphragm system with PTFE-coated wetted components for enhanced chemical resistance and long-term durability.
The oil-free operating mechanism eliminates contamination risks and reduces maintenance requirements, making the pump suitable for sensitive analytical and chemical workflows. Its two-stage pump design provides stable vacuum generation with improved operational efficiency for demanding laboratory applications.
LMVP20 delivers a flow rate of 20 L/min with an ultimate vacuum of 20 mbar, supporting applications such as vacuum filtration, rotary evaporation, vacuum distillation, centrifugal concentration, and solid phase extraction.
The PTFE-coated diaphragm and corrosion-resistant construction enable reliable handling of aggressive chemical vapors and corrosive gases commonly encountered in chemical, pharmaceutical, and petrochemical laboratories.
Designed with low vibration and direct motor power transmission, the pump maintains stable operation with low noise levels below 70 dB. An integrated overheat protection mechanism and automatic temperature stabilization system further improve operational safety and reliability during continuous use.
