Shandong Zibo Boshan
ZJ series Roots vacuum pump is a volumetric vacuum pump, also known as mechanical booster pump. It is one of the main pumping equipments for obtaining medium and high vacuum. Its working principle is similar to that of Roots blower. It uses two 8-shaped shapes. The rotor rotates synchronously within the pump casing to complete the suction and exhaust.
For the chemical, pharmaceutical and other industries requiring the industry to remove a large amount of water vapor and solvent technology, our company has improved the sealing structure of the ZJ series Roots vacuum pump pump chamber and bearing cavity, greatly reducing the oil emulsification of the bearing cavity and gear chamber. The phenomenon makes the ZJ series Roots vacuum pump more suitable for mixing a large amount of water vapor and solvent with the water ring vacuum pump. At the same time, the over-current parts of the rotor, pump body and end cover of our company are nickel-plated, which greatly prolongs the Roots pump. The service life of the corrosive gas is removed, and the rust of the Roots pump is effectively prevented.
For the working condition of removing the solvent which is highly corrosive to rubber, we have designed a mechanical seal structure for the pump chamber and the bearing chamber at four places and a shaft extension end, which is referred to as "five-point mechanical seal", which is mechanically sealed. The flexible seal is made of corrosion-resistant PTFE material to completely eliminate the emulsification of the pump oil and completely close the passage of the pump oil to the pump cavity. Therefore, the Roots vacuum pump with "five-point mechanical seal" structure can be called real A dry Roots vacuum pump in the sense. If you need a Roots vacuum pump with a "five-point mechanical seal", please specify when ordering.

Note: The limit pressure values listed in the above table are the limit pressures measured when the Roots vacuum pump is equipped with a rotary vane vacuum pump or a slide vacuum pump with a suitable pumping rate as the foreline pump, such as a water ring vacuum pump or a oil cup vacuum pump. As the foreline pump, the ultimate pressure will be higher than this value. For the specific parameters, please refer to the Roots Liquid Ring Vacuum Unit.
