Utilize a single spring coiled in a right of left hand design to accommodate left and right hand turning pumps. They have the flexibility to accommodate misalignment, shaft deflection, and break away shock loading. It resists clogging in extremely viscous fluids.
All mechanical seals are constructed of three basic sets of parts:
1) A set of primary seal faces: one that rotates and one that remains stationary.
2) A set of secondary seals known as shaft packings and insert mountings, such as o-rings, rubber boots, PTFE or Grafoil wedges, or V-Rings.
3) Mechanical Seals have hardware including gland rings, collars, compression rings, pins, springs, retaining rings and bellows.
