| Diaphragm vacuum pumps LABOPORT®-SD, chemically-resistant With self-drying system for vacuum drying. Oil-free, positive displacement pumps for neutral, highly aggressive or corrosive gases and vapours. Unadulterated, pumped gas / vapour output. Constant vacuum. More environment-friendly and cost-effective than water jet pumps. The new self-drying system enables condensate to be blown out of the pumphead at high speed during the evacuation process. The vacuum in the vessel being pumped remains constant. The drying cycle can be synchronised in three different ways according to individual process requirements. With drying the pump achieves a better vacuum and can evacuate more quickly than pumps without drying systems. Pump components that come into contact with media Pump head: PTFE Diaphragm: PTFE Valves: FFPM Supplied as follows: Chemistry laboratory vacuum pumps are complete instruments that are ready for connection with mains switch, mains cable (supply requirements: 230V / 50Hz, other voltages and frequencies available on request) and fully automatic self-drying system. Easy connection to vacuum desiccator cabinets. Product Specification: Product Type: N 820.3 FT.40.18 Flow rate: 20 L / min. Ultimate vacuum: 10 mbar (abs).
