VRA seals

null

The VRA is an outside-mounted, dry-running single pusher seal designed to operate on top-entry agitators and mixers.
Self-lubricating carbon or filled PTFE seal faces run completely dry without cooling.
Cost savings provided by contacting dry-running design and two-piece collar, which respectively eliminate the need for a buffer fluid system and expensive alloys in non-wetted areas

Press: vacuum to 13.8 bar (200 psi)
Temp: to 121°C (250°F)
Speed: to 350 rpm
Sizes: 25 to 178 mm (1.000 to 7.000 in)

FEATURES & BENEFITS

  • Optimized for high run-out requirements — up to 3.81 mm (0.150 in) FIM
  • High reliability provided by flexible rotor design that compensates for misalignment and double O-ring mounted stator that prevents distortion
  • Reduced downtime facilitated by optional sanitary gland that allows steam cleaning and sterilizing of the seal’s interior while mounted on the equipment

MSS mixer split seal

null

The MSS is for tough mixer and vessel applications where stuffing box face, bore and OD run-out are extreme. Typically used on older equipment or where compression packing had been used.
Easy installation, inspection and maintenance facilitated by outside seal arrangement and split design
