Packing used specially for mechanical pump is also called water-base packing. This product is a packing used specially for mechanical pump, which is made by vegetable fibers as the main body with adding special type lubricant in it. It can be met with the requirements of all sorts of pumps in the installations of oil refining, chemical, pharmacy, food, iron and steel as well as water treatment, such as centrifugal-pump, spin-pump, reciprocating-pump and turbo-pump etc.

Physical and chemical parameters of the packing:

1,Permit working temp: -60℃—270℃
2, Permit working pressure: 190kg/cm2
3,Max line speed: 12m/s
4, PH: 5-11
5,Resilient ratio: 30%
6, Density: 1.4~1.7g/cm3

Type 825 High Elastic Packing

    The internal elastic-force compensating of the packing is composed by inner-core of high elastic materials. It makes this product to have avoided the sealing invalidation, which is caused by shaking and clearance increasing of sealing place led to equipment aging. Selecting combination of fibers and elastomers according to different medium, temperature and pressure can produce the product.
