C900 Variable Frequency Series

The C900 Variable Frequency Series by Wiggens delivers advanced chemical-resistant diaphragm pumps for aggressive gas and vapor handling in demanding laboratory settings. Distributed in South Africa by Apex Scientific, this high-performance equipment line includes four models—C900EF, C920ZF, C960TF, and C980VF—built for large-capacity vacuum applications like distillation, filtration, drying, and semiconductor processing.

 

Precision Vacuum Control

Each pump pairs with a variable frequency controller to adjust motor speed, enabling faster pumping and a stable vacuum. The series supports flow rates up to 95 L/min and achieves vacuum levels as low as 1 mbar—ideal for large-volume distillation, enrichment, and reactor systems.

 

Durable Chemical Resistance

Wetted parts use high-grade PTFE or PTFE-coated materials for long-term resistance to corrosive media. These pumps ensure high-purity operation with low contamination risk in harsh chemical processes.

 

Low-Noise, Safe, and Easy to Maintain

With a quiet, low-vibration design, these pumps suit sensitive **laboratory** environments. Overheat protection automatically halts and restarts operation if needed. Maintenance is simple, keeping downtime to a minimum.

 

Flexible Model Options

Each model offers unique performance while preserving the Wiggens oil-free and durable design. Whether you’re in pharmaceuticals, semiconductors, or chemical processing, you can achieve reliable vacuum control with minimal upkeep.
