Vacuum Pumps, Oil Free PTFE Diaphragm Chemically Resistant Laboratory Chemker Models 300, 400, 410 and 411

  Overview

The Rocker Chemker Models 300, 400, 410 and 411 oil free PTFE diaphragm chemically resistant vacuum pumps require no lubricant, regular oil changes or other routine maintenance. The oil free diaphragm design means that the pumps are cleaner in operation. All wetted parts of the Chemker pumps are made of PTFE, so they can resist most corrosive gases.

A direct drive motor eliminates the noise and complications of a belt drive and together with careful vibration lowering design and assembly results in low 50.0 dB noise levels. The motors automatically shut down if overheated and restart when they have cooled off.

The Chemker Model 411 has an attached external Glass Moisture trap/ Vacuum Regulator.

Whatever the laboratory application, be it filtration, gel electrophoresis, solid-phase extraction (SPE) or solvent purification, the Rocker Chemker oil free diaphragm vacuum pumps are ready to give dependable long term service in harsh conditions.

Features of the Chemker 300, Chemker 400, Chemker 410 and Chemker 411 Oil Free PTFE Diaphragm Vacuum Pumps:
  • No oil pollution, cleaner operating
  • Diaphragm pumps need no lubricant, regular oil changes or other routine maintenance
  • All wetted parts made of PTFE to handle most corrosive atmospheres
  • Direct drive motor with no transmission means lower noise than comparable models
  • Careful design and assembly reduces vibration
  • Thermal protection in case of overheating, with automatic restart
  • Glass moisture trap/Vacuum regulator (Chemker Model 411)
