Horizontal-type vacuum pump geared toward vacuum drying equipment.

The "TRM Series" is a versatile roots-type dry vacuum pump with many years of experience and numerous achievements. It can operate efficiently and stably at a consistent temperature thanks to what we call "back-flow cooling system". Additionally, as this pump is capable of collecting condensates that generate during the vacuum process, it is suitable for handling condensable gases in applications like vacuum drying, distillation, and degassing. This pump can cover a wide range of pumping speeds from approximately 2 m³/min to 35 m³/min and can be designed to accommodate special requirements requiring corrosion-resistant materials such as electroless nickel plating, and stainless steel. 【Features】 ○ Wide operating range ○ Completely dry ○ No water contamination ○ Long-term continuous operation For more details, please contact us or download the catalog.
