Product Description

Product Description

Product advantage

 

 Product advantage

· A larger pumping rate in a wide pressure range. Like an "accelerator" used on a front pump to increase its pumping speed and extreme vacuum.
· The operating parts of the pump have no friction and no oil in the pump chamber, so a clean vacuum can be obtained.
· The vertical flow of gas in the pump chamber is conducive to the removal of dust and condensate in the pumped gas.
· The fully symmetrical and precise dynamic balance rotor runs smoothly and reliably.
· Prevent oil leakage and emulsification- -the application of shaft extension mechanical seal and compartment composite sealing structure design.
· Small vibration and low noise.
· Compact structure, low driving power, and low operation and maintenance costs.
