Product features
1. There is no contact between the gas and the bearing, the pressurized element bearing the lateral force is transferred from the high temperature area to the low temperature area, and the service life of the bearing and the guide ring is doubled. Special relubrication structure makes
maintenance faster.
2. The unique mid-body sealing structure improves the life of the seal and provides excellent sealing effect. The leakage is less than 4/1000, which ensures the purity and cleanliness of the gas after pressurization and prolongs the service life of the raw material machine.
3. Applicable gas: Nitrogen/Air, Oxygen(piston rings are different, please specify when ordering)
4. Pressure Range: ≤50 Barg
5.Flow Range: ≤240 m3 /h (Larger flow can be customized)
