Rocker – Chemical Resistant Vacuum Pump (Chemker 400)
The wetted parts of the Chemker 400 and all products in this line are made of PTFE material that resists most corrosive gases. They are diaphragm controlled and require no lubricant, no periodic oil changes, and no maintenance; no oil contamination. Thanks to the vibration-proof design, the Chemker Series has the lowest noise level of any comparable pump. Each Chemker Series vacuum pump motor has a built-in thermal protection device that automatically shuts down the pump if it overheats and restarts it when it cools down.
- Solvent purification
- Solid-Phase Extraction (SPE)
- Gel electrophoresis
- Vacuum filtration
- High chemical resistance
All wetted parts of Chemker series pump are made of PTFE material which can resist most of corrosive gases.
- No air pollution, maintenance free
Chemker series pumps are driven by Diaphragm, without the need of lubricant, regular oil changes and maintenance; with no oil pollution.
- Quiet and low vibration
Driven direct by motor with no additional belt-driven transmission; the quality vibration-proof assembly makes Chemker series run at the lowest noise level among all other equivalent pumps.
- Thermal protection device
Every motor of Chemker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
