Extremely robust against condensate! Vertical dry vacuum pump for chemical processes.

The "TRV Series" is a versatile dry vacuum pump (Roots vacuum pump) uniquely developed as a vacuum pump that is strong against condensable gases. The gas flow path is arranged to flow from the top to the bottom in a Down-Flow manner, allowing mist and liquids condensed inside the pump, which are drawn in with the gas, to easily flow down to the discharge port and be expelled or collected under atmospheric pressure. Therefore, it is an extremely robust pump against the inflow of mist and condensate from gases. In addition to the standard FC material, corrosion-resistant materials are also available for selection. 【Features】 ○ Strong against liquids ○ Energy-saving and high-performance design ○ Low temperature rise ○ Capable of drawing high-temperature gases ○ Small installation footprint For more details, please contact us or download the catalog.

Are you having trouble with the suction of corrosive gases? We will solve the problem with our thick film fluoropolymer-coated vacuum pumps.

  • Product news

The lineup of vertical dry vacuum pumps "TRV Series," suitable for chemical processes, has been enhanced with a thick film fluoropolymer coating. These pumps can handle highly corrosive acidic and alkaline gases that cannot be managed with stainless steel, making them suitable for hard processes. The 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, their small footprint makes them suitable for integration into equipment. 【Features】 ■ Compatible with 200μm thick fluoropolymer coating ■ Stable operation 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 motors can also be explosion-proof Basic Information 【Specifications of Fluoropolymer Coating】 Type: PFA (antistatic) Coating Thickness: 200μm *Equivalent to pinhole-free products Properties: Chemical resistance, non-stick, water and oil repellency *For more details, please refer to the materials. Feel free to contact us with any inquiries.
