Chemvak A series vacuum pumps by Wiggens deliver exceptional chemical resistance and consistent performance in demanding laboratory environments. With PTFE-coated wetted surfaces, these pumps efficiently handle corrosive vapors in chemical, pharmaceutical, and petrochemical applications. Designed for scientists in South Africa, the Chemvak A Series is part of the trusted laboratory equipment range offered by Apex Scientific.
Oil-Free, Low-Maintenance Operation
The Chemvak A series features a direct-drive diaphragm system, which eliminates oil, lubricants, and belt-driven parts. This actively reduces maintenance needs while delivering clean, oil-free operation. Moreover, with noise levels below 50 dB, these pumps are ideal for quiet, precision-based lab settings. Each model includes thermal protection that automatically shuts off the pump during overheating and restarts it once temperatures normalize—ensuring consistent performance and safety.
Corrosion Resistance and Versatile Applications
Built with corrosion-resistant materials, these pumps perform reliably in environments with aggressive gases and solvent vapors. They are perfect for rotary evaporation, vacuum filtration, vacuum distillation, solid phase extraction, and vacuum concentration. With vacuum capabilities reaching 8 mbar, the Chemvak A series efficiently supports a wide range of applications in modern South African laboratories.
Multiple Models for Different Lab Needs
This series includes several models, each offering specific flow rates and vacuum depths. Whether you need a compact pump for everyday tasks or a powerful system for demanding processes, Chemvak delivers a tailored solution to match your workflow.
