moreThe use of Nitrile Butadiene Rubber NBR as seal in machines has increased in recent years. NBR is considered as the standard material for sealing and NBR owes its many applications to a range of special mechanical properties. However, the non-linear mechanical properties and incompressible behaviour of NBR make the analysis of NBR very difficult. The most common technical cause of hand pump failures was the wear of the piston seals. Contact surface of the piston seals and the piston seal contact area are the key of calculating and determining friction force and seal wear rate of hand pump NBR rubber piston seal.
