- Commodity name: Screw Pump Piston Ring Seal
- 副标题: Suitable for Elma VDP70–VDP2800
A set of complementary seals consisting of piston rings and piston ring seats. The piston ring seat is securely mounted on the rotating shaft, while the piston rings are precisely fitted into grooves within the seat. Thanks to their inherent tension, they maintain a tight seal against the pump housing walls, ensuring efficient sealing even during rotational motion.
ELMVAC-VDP Screw Pump Dedicated Piston Ring Seal
Main function:
1. Sealing Oil: Prevents lubricating oil from leaking from the bearing chamber/gearbox along the shaft into the clean vacuum chamber, thereby avoiding contamination of the process.
2. Sealing Atmosphere: Prevents external air from being drawn back into the vacuum chamber through the shaft gap, thereby ensuring the pump achieves its ultimate vacuum level.
Common applications: Widely used in oil-lubricated dry vacuum pumps such as Roots pumps and screw pumps.

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.
