Recommended information

TRV Series Vertical Dry Vacuum Pumps Compatible with Thick Film Fluororesin Coating

TRV Series Vertical Dry Vacuum Pumps Compatible with Thick Film Fluororesin Coating

For the suction of highly corrosive acidic and alkaline gases. Adopts a thick film fluororesin coating (200μm). The unique vertical structure facilitates the recovery of condensed liquids.

The lineup of the vertical dry vacuum pump "TRV Series," suitable for chemical processes, has been enhanced with a thick film fluororesin coating. It can handle hard processes that involve highly corrosive acidic and alkaline gases that cannot be managed with stainless steel. Its unique vertical structure is designed so that the gas flow path runs from the top to the bottom, allowing mist and liquids condensed inside the pump, which are drawn in with the gas, to flow down to the discharge port and be easily expelled and recovered under atmospheric pressure. Additionally, its small footprint makes it suitable for integration into equipment. 【Features】 ■ Compatible with 200μm thick film fluororesin coating ■ Stable operation possible from atmospheric pressure to cutoff operation ■ Capable of drawing high-temperature gases up to 120°C ■ Wide vacuum range supported by combination with mechanical boosters ■ Electric motor can be explosion-proof *For more details, please download the PDF or feel free to contact us.
