Vacuum Pump, Roots Vacuum Pump,ZJ150 Roots Vacuum Pump

The Roots vacuum pump is also called mechanical booster. It is the main pumping equipment in the middle 

or high vacuum. Its working principle is similar to the Roots fun by two rotors whose shape is like "8" 

and move synchronously to achieve the suction and discharge.

According to the technics for pumping amount of steam in the chemical, pharmacy and so on, we improved 

the sealing structure of the pump cavity and bearing housing so as to reduce the oil emulsification in 

the bearing housing or gear box efficiently. So the ZJ series Roots vacuum pumps are more suitable to 

pump amount of steam or solvent.

Main characteristcs: 
Higher suction capacity in wide pressure scope from 1 to 1×104Pa.
To prevent the oil steam to pollute the vacuum system for without any oil in the pump cavity.

 Less libration, lower noise.
 Less mechanical attrition, lower power.
 Easy to maintain and repair, low cost but long life.

To pump the coagulated gases. 
They cannot be used separately and should be connected with a fore pump. The Roots pump are not allowed 

to start under the atmosphere until the inlet pressure of the fore pump reaches the vacuum approved by 

the Roots vacuum pump. The fore pump is water ring vacuum pump, oil ring vacuum pump or oil sealing 

mechanical pump.
For pumping the amount of steam or solvent, the Roots vacuum pump structure is improved in order to 

avoid oil emulsification in the gear housing.
