Our company has developed a series of soft-sealed plunger products.

Through continuous research and testing, our company has developed a series of soft-sealed plunger products with specifications of 106, 125, 150, 175, and 200. We can not only manufacture the soft-sealed plungers but also produce a series of soft-sealed rings. Soft-sealed plungers help reduce leakage in oil extraction pumps, improve oil recovery efficiency, and effectively minimize sand abrasion on the pump barrel and plunger in sand-laden wells, thereby extending the service life of the extraction pump. Compared to plasma-sprayed plungers, soft-sealed plungers are significantly more cost-effective.
