Our ZJ series Roots vacuum pumps are widely used in the vacuum degassing, vacuum melting, and vacuum surface treatment in the metal and non-metal material industries. When串联 with the WLW oil-free vertical vacuum pump and water ring pump, they are particularly suitable for vacuum polymerization, reaction, decomposition in the chemical industry, as well as vacuum distillation, vacuum drying, and vacuum crystallization processes in the food industry.
Features - Roto-Rooter Pumps
1. Capable of achieving a high suction capacity over a wide pressure range.
2. Oil-free pump cavity to prevent oil vapor contamination of the vacuum environment.
3. Energy-efficient, easy maintenance.
4. Must be used with a preliminary pump; not to be used alone.
