Greased Purged Seals (GPS Series)
A seal’s a seal, right? Not anymore.
Our revolutionary Grease Purged Seal (GPS) is a major step forward. Unlike
most others, our GPS seals are constructed of elastomers that center on the
shaft – and flex with it.
How GPS seals work
Our revolutionary seal is comprised of multiple nitrile seals stretched over the
rotating shaft. Some seals face inward (toward the product), while some face
outward (away from the product).
The key to our GPS seal’s success are the inward seals – they maintain a
tighter seal than those to the outside and decrease the likelihood of grease
contamination reaching the product. The gap between these two seals is filled
with grease through a remote “zerk” or other fitting. Other features include:
- Low Profile: The GPS seal is capable of retrofit into
areas where waste pack and air purge seals were once used, allowing the use of
standard 4-bolt flange bearings, and interchangeability with other seal
- Effective up to 250º F and 15 psi (higher for short durations):
We are continuing to test elastomers and grease that will tolerate even higher
temperatures and pressures.
- Made with Heavy Gauge Elastomers: Nitrile or other
compounds that provide you with useable life after years of running with
average products. This design helps to create a seal that is more flexible and
tighter, allowing it to conform to the shaft and remain effective even in high
- Easy Retrofit: The GPS seal will replace most waste pack
and air purge seals already on the market with ZERO interchangeability
problems. Throw out that leaky waste pack. Toss the air purge seals (and the
regulator and air lines as well). Simply bolt the GPS seal in behind the
flange bearings you’re currently using and you’re ready to go. What about a
leaking flanged/packing gland seal? We can create a custom seal that will fit
– and at a reasonable cost.
- Custom Designs Available: GPS seals can be modified to
fit your company’s needs and increase the pressure resistance of your seal.
The grease used can be petroleum based, synthetic, or food grade. The lips can
be installed to ensure any grease purge leakage occurs away from the product.
Custom metal components, special patterns and stack-up dimensions and higher
pressure resistance are a simple matter.
- Successful in Difficult Applications: We have had
repeated success sealing against hexane, high head loads of sugar, cooled fly
ash, etc. The seals have lasted more than a year with only lubrication
GPS seals are as close to installing and forgetting a seal as you can get.
