Chemvak C Series vacuum pumps by Wiggens deliver outstanding chemical resistance, low noise, and long-term durability. Built for corrosive gas and vapor handling, these oil-free diaphragm pumps suit a wide range of applications in the chemical, pharmaceutical, and petrochemical industries. As part of Apex Scientific’s advanced laboratory equipment range, they provide reliable and eco-friendly vacuum solutions to labs across South Africa.

 

High Chemical Resistance and Oil-Free Performance

All wetted components in the Chemvak C Series use corrosion-resistant PTFE. This ensures consistent performance from inlet to exhaust, even under harsh conditions. Because they operate oil-free, these pumps avoid contamination, reduce maintenance, and eliminate the need for waste disposal associated with rotary vane or water-jet systems. As a result, they offer a cleaner and more cost-effective solution for modern laboratories.

 

Quiet, Safe, and Durable by Design

Each model features a direct motor drive with a vibration-resistant build. This design keeps noise levels low—ideal for quiet working environments. Additionally, the reinforced PTFE-coated diaphragm and head cover extend product lifespan. For added safety, the built-in thermal protection shuts the pump down during overheating and restarts it automatically once cooled.

 

Versatile Models for Every Lab

The Chemvak C Series includes a wide range of models (C300–C610). Each supports different vacuum levels and flow rates. Whether you’re running rotary evaporation, distillation, or gel drying, there’s a model tailored to your process.

 

Engineered for Demanding Applications

These pumps handle vacuum filtration, concentration, and solvent processing with precision. Their smooth surfaces simplify cleaning, while advanced seals reduce leakage. They are CE-certified and built to deliver reproducible results in South African labs.
