Seals for Rotating Service
Engineered Sealing System
—the leak-free, no dilution sealing
system designed to replace
mechanical seals in industrial
pumping applications.
The Best Option for Slurry Service
Garlock has created a long life seal that will increase reliability
and process yield while conserving water and energy.
Hydra-Just combines the best of both worlds; like a
mechanical seal, Hydra-Just provides leak free, no dilution
service and saves energy and water because of the
low friction design. Like conventional packing, Hydra-
Just can accommodate system upsets and is not subject
to catastrophic failure.
The Choice for Water Reduction
Up until now, mechanical seals were the most water efficient
rotary seal on the market. As a rule of thumb, a
mechanical seal requires 1 US gallons per minute per
inch of shaft diameter. Hydra-Just runs with 98% less
water than mechanical seals requiring as little as 3
US gallons per hour. To put this in context, replacing
a mechanical seal that requires 2 USGPM of flush with
Hydra-Just will save over 1,000,000 US gallons of water
per pump.
Designed For Outage-to-
Outage Performance
This robust seal enables users to increase profitability
through improved process yield. The process exclusive
design of the Hydra-Just ensures a seal with the versatility
to handle a wide range of system upsets and excel in abrasive
slurries. Additionally, the Hydra-Just seal requires no
adjustment, freeing up maintenance resources to focus on
other areas of the plant.
Easy to Install
Hydra-Just customers can realize production increases
by getting back on line faster. The components of the
Hydra-Just allow the seal to be installed without uncoupling
the motor.
