Vacuum Pump, Chemker 611, Chemical Resistant, 50Hz

This Chemker 611 Vacuum Pump is specifically designed for laboratory applications requiring high chemical resistance.

All wetted parts are constructed from PTFE, offering excellent resistance to most corrosive gases. This makes it suitable for a variety of tasks involving aggressive solvents and vapours.

Reliable Start-Up Against Vacuum

This unit is engineered to start against vacuum - this feature is particularly advantageous in workflows where the pump needs to stop and restart during operations, such as with rotary evaporators and vacuum filtration systems.

Integrated Moisture Trap & Vacuum Regulator

Equipped with a built-in vacuum regulator and moisture trap, the Chemker 611 allows users to adjust vacuum levels precisely. The moisture trap collects condensation, helping to extend the pump's service life and reduce maintenance frequency.

Maintenance-Free & Environmentally Safe

The diaphragm-based mechanism of the Chemker 611 eliminates the need for oil, removing the risk of air contamination and avoiding routine oil changes or lubrication. This results in a maintenance-free, eco-conscious operation ideal for clean lab environments.

Quiet & Low Vibration Operation

With direct motor drive and no belt-driven components, the Chemker 611 maintains minimal vibration and low noise levels. Its vibration-damping design ensures quiet operation, enhancing user comfort and reducing noise pollution in the laboratory.

Built-in Thermal Protection

The pump features an integrated thermal protection device that automatically shuts off the motor in the event of overheating. Once cooled, the unit resumes normal operation, safeguarding the equipment and ensuring operational safety.

Certifications & Warranty

It is CE certified and supported by a 12-month manufacturer’s warranty, providing assurance of product reliability and quality.

Typical Applications

This pump is suitable for use with rotary evaporators, concentrators, vacuum drying ovens, solvent purification systems, vacuum filtration setups, and other general laboratory vacuum requirements.
