Packings have been the most widely used seals for many years. Fabric materials are used in the packings, which wrap around the pump shaft, fill the dead space and minimize fluid loss.

product introduction:

Packings are considered moving seals and a type of seal, which dynamically seal on the piston and shaft of pumps. The performance of the packings is one-way and two-way and can withstand pressure from 250 to 700 bar. In some cases, a support ring is also used to withstand more pressure in the packing. Packings, like other sealing parts, have the task of preventing liquid leakage to the main part of the device. Packings are usually made of natural or synthetic rubber, each of which can vary in terms of appearance and material depending on the type of application.
