Chemical-resistant diaphragm pumps

Vacuum performance is critical in laboratory and pilot-scale processes, particularly where corrosive gases or aggressive solvent vapours are present. Chemical-resistant diaphragm pumps provide an oil-free and reliable solution for applications requiring strong chemical compatibility, stable operation and low maintenance.

The C Series pumps from Wiggens feature a multi-stage design that combines high pumping speed with strong ultimate vacuum performance. All wetted components are manufactured from PTFE, making the system suitable for highly aggressive or corrosive media. A refined sealing system helps minimise leakage and supports vacuum levels down to 1 mbar.

Designed for demanding workflows such as pilot reactors, rotary evaporation, semiconductor processing and drying applications, the pumps deliver a maximum flow rate of up to 145 L/min, supporting efficient evaporation, drying and gas handling.

Frequency conversion technology enables rapid attainment of target vacuum levels while maintaining stable operation throughout use. It also helps reduce noise output and extend service life, contributing to quieter and more efficient laboratory environments.
