Wiggens Diaphragm Pump C400, Ultimate vacuum: 120mbar, max flow rate: 34L/min

The C series, constructed with PTFE, offers exceptional resistance to chemical vapors from inlet to exhaust, as well as high tolerance to condensates
The hermetically sealed pumping chambers ensure extended durability of the mechanical components. Most importantly, these diaphragm pumps are oil-free, significantly reducing service requirements compared to oil-sealed pumps
They eliminate the water costs and contamination issues associated with water-jet aspirators, as well as the waste-oil disposal concerns of rotary vane pumps. These pumps are chemically resistant and designed to handle highly aggressive acidic, basic, and solvent vapors, thanks to the corrosion-proof PTFE coating on all wetted surfaces
Through advanced mechanical engineering and user-friendly design, we have developed the C series to be quiet, safe, maintenance-free, and cost-effective. High Chemical Resistance: All wetted components of the C series pumps are made from PTFE, making them ideal for extremely corrosive gases and vapors. Long-Term Durability: The pump head and diaphragm are made of PTFE or PTFE-coated materials with a stable core, providing unrivaled long-term performance. No Air Pollution, Maintenance-Free: The Chemvak C series pumps are powered by diaphragms, eliminating the need for lubricants, oil changes, or regular maintenance—resulting in zero oil pollution. Practical Design: The smooth surfaces allow for easy cleaning, and the sealing system minimizes leakage, ensuring an improved ultimate vacuum performance.
