ROCKER Chemical Resistant Vacuum Pump, Chemker 400 169400-22

Chemker 400 Chemical Resistant Vacuum Pump (part number 169400-22) is an oil-free, diaphragm-driven laboratory vacuum pump designed for handling corrosive gases and solvent applications; it is specified for AC220V, 50Hz operation. The pump provides a compact, quiet and stable vacuum source for solvent purification, vacuum filtration, gel electrophoresis and other laboratory procedures requiring chemical resistance. Wetted parts are constructed from PTFE and FFKM for superior chemical resistance, and the unit incorporates motor-driven transmission with vibration-proof assembly and overheat protection for safer, long-lasting operation.

Key Features:

• Part number: 169400-22 (AC220V, 50Hz)
• Max. power: 90 W
• Max. current: 0.5 A
• Max. vacuum: 99 mbar abs.
• Max. flow rate: 33 L/min
• Noise level: 52 dB
• Hose barb: ID8; Net weight: 7.0 Kg; Dimensions (L×W×H): 27 × 11 × 18 cm

Advantages:

• Superior chemical resistance via PTFE and FFKM wetted parts suitable for corrosive gases.
• Oil-free, diaphragm-driven design requires no lubricant and is maintenance-free and oil-mist-free.
• Quieter and more stable operation from motor-driven transmission and vibration-proof assembly.
• Built-in overheat protection that shuts down the pump when overheated and resumes when cooled.
