VPM vee packer seal is normally used in multiples in a set with male and female adaptors. The parts are 'stacked' together and are lubricated liberally with clean operating fluid prior to assembly. VPM must be axially pre-loaded by the housing. This pre-load works through the male adaptor on the pressure side, exerting a hinging action, forcing the sealing lips apart to ensure a low pressure seal. As pressure and hinging action increases, it increases the effectiveness of the seal even where severe vibration may occur.
Applications
High pressure rod and piston sealing applications
Used in steel mill and hydraulic press applications
Fluids
Mineral based oils, water/glycol and water emulsions
