Rocker – Chemical Resistant Vacuum Pump (Chemker 611)

The wetted parts of the Chemker 611 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.

Ideal for:

  • Rotary evaporator
  • Concentrator
  • Vacuum drying / oven / defoaming
  • Solvent purification
  • Vacuum filtration

Rocker – Chemical Resistant Vacuum Pump (Chemker 611)

Key Features

  • High chemical resistance
    All wetted parts of Chemker series vacuum pump are made of PTFE material which can resist most of corrosive gases.
  • Start against vacuum
    Chemker 600 series vacuum pumps, designed to start against vacuum, are ideal for various kinds of laboratory instruments which need to stop and restart pump repeatedly during operating process.
  • Vacuum regulator / Moisture trap
    Chemker 611 vacuum pump is equipped with vacuum regulator and moisture trap used to adjust vacuum level and collect condensation to prolong the life of pump.
  • No air pollution, maintenance free
    Chemker series vacuum 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 run at the lowest noise level among all other equivalent pumps.
  • Thermal protection device
    Every motor of Chemker series vacuum 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.
