BMG’s range of Garlock sealing products includes a versatile sealing system that replaces mechanical seals in industrial pump applications.
Garlock’s Hydra-Just is a reliable, leak-free rotary sealing system which consists of a minimal number of components and comes completely split. This eliminates the need for a costly dismantling process or back-up equipment. Machinery can be serviced without having to uncouple the motor.
“Because this system provides cool, dry operation with no product dilution, overall water consumption is significantly reduced. Unlike mechanical seals, this sealing system can withstand fluctuations in water pressure and is more effective in high pressure, low flow conditions,” says Ken Steel, general manager of BMG’s seals division.
“With this system, which uses braided rings in conjunction with other high performance materials, a truly leak-free rotary seal is created, with no risk of catastrophic failure. This means users are able to optimise uptime and schedule maintenance around production needs, rather than re-scheduling production around seal failures.”
These low maintenance Hydra-Just seals, which are easy to install, can be used in the same places a single mechanical seal. The sealing system has high abrasion and chemical resistance which allows efficient operation, even in demanding environments.
Important components of the system are the flowmeter, needle valve and pressure gauge which regulate and measure the pressure of seal water. The barrier pressure ring efficiently directs seal water pressure in such a way as to maintain equal force on the inboard and outboard seals. No additional equipment is required with this system.
Because the seals do not use a machined seal face, this system can tolerate moderate amounts of wear in the stuffing box. If equipment is within the manufacturers’ design tolerances, the Hydra-Just seal will make the seal.
