Product Information :

The Jabsco seal # SP6080-0391 is a Hygienic hard faced pinned Mechanical Shaft Seal, wave spring type, with Tungsten-Carbide on Tungsten-Carbide rotary faces. This is a high quality mechanical shaft seal designed to prevent leakage of product from the pump into the atmosphere and to prevent contamination by airborne micro-organisms. The seal design has a simple cartridge design and set-up, and is externally mounted into the rear of the rotor case which means that the drive collar, locating screws and wave spring are outside of the product, this ensures that good hygiene levels may be achieved for maximum cleanliness. The rotary seal face is driven by 2 pins that locates in slots in the drive collar. This means that the seal can be run equally well in both directions of rotation. This anti-rotation pin in the seal seat allows use on high viscosity products, and allows bi-directional rotation. The Tungsten-Carbide/Tungsten-Carbide seal faces are energized by a simple wave spring, which is used to keep the rotary and static seal faces in contact at low pressures. At higher pressures the static seal seat pistons backwards and forces the rotary face, mounted on the shaft, back against the drive collar. This compresses the wave spring and eliminates fatiguing of the spring.

Applications:

This single Tungsten-Carbide on Tungsten-Carbide seal is used where viscosities are higher than 150,000 centipoise and also where carbon is not acceptable in fluid contact or where face wear would be unacceptable. It can be used for abrasive fluids containing crystals, powders or particles which would rapidly wear away the carbon of the standard seal, and where shedding of particles into the fluid stream must be avoided. The seal faces are the only area in the pump design where rubbing contact is unavoidable. Tungsten-Carbide is extremely hard, so the seal does not wear and thus particles are NOT shed into the product. Note that Tungsten-Carbide on Tungsten-Carbide seals are not recommended for steam-purged applications as the seal faces can bind together.

Seal Design:

These seals use proven, very effective designs, highly utilized in many applications. The seal design has a simple cartridge design and set-up, and is externally mounted into the rear of the rotor case which means that the drive collar, locating screws and wave spring are outside of the product, this ensures that good hygiene levels may be achieved for maximum cleanliness. The rotary seal face is driven by 2 pins that locates in slots in the drive collar. This means that the seal can be run equally well in both directions of rotation.

The Tungsten-Carbide/Tungsten-Carbide seal faces are energized by a simple wave spring, which is used to keep the rotary and static seal faces in contact at low pressures.
