Silicone bushing playing a role of liner is mostly applied in the field of valve,which is in the valve bonnet , wrapping the valve stem. A bushing or silicone bushing is a type of vibration isolator, it provides an interface between two parts, damping the energy transmitted and to absorb shock and reduce vibration through the bushing.
Â
 Bushing Function
The bushing can be replaced very conveniently if it is worn out. If you don't use the bushing, you have to replace the whole part once abrasion. Now, people tend to replace the bushing (while designing, the hardness of bushing can be reduced to be a bearing grinding of friction pair), due to its convenient processing, low replacement cost and easy replacement, of course, also including other secondary functions, like guiding function, and etc. Â
Â
A common application of bushing is in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic rubber or polyurethane) separates the faces of two metal objects while allowing a certain amount of movement. This movement allows the suspension parts to move freely, for example, when traveling over a large bump, while minimizing transmission of noise and small vibrations through to the chassis of the vehicle. A silicone bushing may also be described as a flexible mounting or antivibration mounting.

ID starch pump is a horizontal, single-stage, cantilever Centrifugal Pump. Its rated performance characteristics and installation dimensions conform to the standard ISO2858, and its manufacturing technical conditions conform to ISO5199. This series of pumps absorbs the advantages of KSB pumps and WARMAN pumps. The improvement of the pump makes the solid content of the conveyed liquid up to about 50%. It is specially designed for the transportation of special media with high solid content, precipitation and easy crystallization, and fiber in the starch, sugar, food, pharmaceutical, chemical and other industries. Put an end to "running", "running", "leakage", "blocking" and other phenomena, China Starch Association "starch equipment localized first-class product".
The impeller design of the ID series pump is based on the solid content of the conveying slurry, whether it is crystallized and glued, the size of the solid particle size, and the length of the suspended fibers. The impeller can be designed to be closed and the flow channel is widened on the premise of not affecting the rated performance. , semi-open, open, swirling, etc., the seal can be designed as single-end or double-end mechanical seal, with impeller plus packing seal, plus impeller plus skeleton oil seal, etc.
