ENVIRONMENTAL CONTROL REQUIRED
The NUTECH 3 primary seals are balanced when pressurized by the product or barrier fluid allowing the seal to be used as a double or tandem seal. The barrier fluid can be used to control the media between the seal faces or for environmental control reasons.
STAND BY SEAL:
Lower barrier fluid pressure idles outboard seal which becomes operational when inboard seal wears out, thus avoiding unscheduled maintenance shutdowns.
Temperature in seal area can be maintained at a level where the product will not crystallize by introduction of a controlled temperature barrier fluid.
PREVENTS PRODUCT HARDENING:
Introduction of barrier fluid excludes air that can cause congealing or hardening of some products.
PREVENTS PRODUCT COOLING:
Products that become viscous during shutdown can be kept warm by the introduction of a higher tamperature barrier fluid.
PREVENTS O-RING HEAT PROBLEMS:
A clean, cool, lubricating fluid can be introduced as a barrier fluid to reduce the temperature at the O-rings thus extending seal life.
POSITIVE PRESSURE BARRIER FLUID:
Introduction of the barrier fluid at 15-25 psi above stuffing box pressure allows the primary seal faces to run on selected media where product in non lubricating or not in contact with seal (top entering agitators, etc).
Typical uses: starch, sugar, pulp liquors, brine, pulp stock, caustic, sewage, asphalt, tar, heavy oils, industrial waste, toxic/hazardous chemicals, vapours, gases, liquid ammonia, latex, congealing foods, fruit/vegetable juices, glue, paint, molasses, wine, whiskey, liquors, mine slurries.
