Polyurethane V-type combination piston rod seal
Good sealing performance, wear resistance, long service life, insensitive to medium pollution, Resistant to impact pressure and vibration pressure, able to work under extremely harsh conditions Allow certain eccentric load and eccentric movement, strong extrusion resistance, even if the surface quality of the piston rod or plunger is poor, it can work effectively for a period of time Suitable for rapid pressure changes , high reliability, can be cut and installed, easy maintenance and replacement. The materials that our company can make include various rubber materials (NBR, FKM, FFKM, SIL, EPDM, HNBR, CI, etc.), various polyurethane materials (oil resistance, hydrolysis resistance, high temperature resistance, food grade, ultra-wear resistance, etc.), various engineering plastics (PTFE, PTFE composite, ultra-high molecular polyethylene, PA, POM, phenolic resin, etc.) and metal materials.

Parameters

The internal open type is suitable for internal positive pressure conditions. The C-ring is a typical self-sealing structure. When the medium pressure enters the C-ring in the working state, the pressure self-tightening effect is generated on the C-ring from the inside to the outside, that is, the greater the system pressure, the better the sealing effect. Due to the principle of opening and self-sealing, it is only necessary to overcome the elasticity of the sealing ring itself during installation, so a very ideal sealing effect can be obtained without using a large pre-tightening force. Our company adopts INCONEL 718 alloy to manufacture.
