- Commodity name: (Air-cooled) Roots Pump Piston Ring Bushing
- 副标题: Suitable for Elam ZJ/ZJQ70-20000
The piston ring bushing is a stationary, cylindrical component with exceptionally high precision in its inner bore machining. It is press-fitted or secured within the shaft hole of either the vacuum pump’s pump body or end cover, ensuring a tight seal between the rotating shaft and the stationary pump housing.
ELMVAC—ZJ/ZJQ (Air-Cooled) Piston Ring Bushing for Roots Vacuum Pumps
Main function:
The key components of the piston ring sealing system. As we previously discussed, the outer circular surface of the piston ring functions under the combined action of spring force and medium pressure,
It is tightly fitted against the inner wall of the bushing, thereby achieving a seal between the rotating shaft and the stationary pump body.

Precision Machining
The forged billet is turned by a CNC lathe to remove most of the allowance, making the shape of the rotor closer to the design size, while leaving an appropriate machining allowance for the subsequent fine processing. The precision machining of the screw profile is carried out using a MAZAK precision machining center. Through precise programming and processing, the profile accuracy of the screw rotor is controlled within the design requirements.
Assembly
After the installation engineer checked the vacuum pump materials, they assembled the vacuum pump products in accordance with the drawing requirements and conducted pressure tests and usage debugging on the assembled vacuum pump products.
Quality inspection
After each processing step of the product is completed, the quality inspection team conducts quality checks based on the processing technology and product standards. Products that do not meet the standards need to be reworked or scrapped.
Shipment
After all processing procedures are successfully completed, the staff responsible for packaging and shipping will check each product against the shipping documents one by one. Once the information is accurate, they will contact the logistics to arrange for shipping.
