This leads to seal failure, causing higher production costs, increased maintenance, environmental concerns and unsafe working environments. Shaft movement and misalignment challenge contact sealing methods, causing them to wear out or groove the shaft. Conventional contact seals, such as mechanical packing, mechanical seals and lip seals, rely on dynamic mechanical contact to seal. Industrial process equipment often suffers from product leakage and contamination due to unreliable sealing. Inpro/Seal Air Mizer ® shaft seals eliminate product loss and contamination on industrial process equipment, decreasing maintenance and production costs. Eliminate seal failure and increase equipment reliability with a permanent sealing solution. Their short and unpredictable service life makes them inadequate to seal industrial rotating equipment. Due to this, they will eventually wear at the point of contact or groove the shaft, becoming ineffective. The High Cost of Contact SealsĬontact seals, such as lip seals, mechanical seals and magnetic seals, are common bearing seals that rely on mechanical contact to seal the bearing housing.
The Inpro/Seal Bearing Isolator’s innovative non-contacting design consists of a unitized stator and rotor that form a compound labyrinth seal with no wearing parts, ensuring permanent bearing protection against lubrication loss and contamination ingress for the lifetime of your equipment.
Permanent Bearing ProtectionĪs the inventor of the Bearing Isolator, Inpro/Seal has delivered proven permanent bearing protection for rotating equipment, including pumps, motors, pillow blocks, gearboxes and more, for over 40 years. Because of this, maintenance professionals place an increased emphasis on bearing protection as a means of improving overall equipment reliability. Over half of failed bearings are caused by lubrication loss and contaminants, such as dirt and moisture, entering the bearing housing. The Importance of Bearing ProtectionĪ leading cause of equipment downtime and lost production, bearing failure impacts equipment reliability across all industries. Inpro/Seal Bearing Isolators ensure permanent bearing protection – increasing the reliability of your rotating equipment.Inpro/Seal Bearing Isolators permanently protect rotating equipment from contamination ingress and lubrication loss, significantly increasing equipment reliability, reducing maintenance costs and unscheduled downtime. Same day shipments are available, even on new designs.Ĭustom engineered designs can be split for easy installation and come with an unconditional performance guarantee. Outside contamination attempting to enter the bearing housing is captured in the outer labyrinth paths and expelled through a port in the stator.īearing lubricant is captured in the inner portion of the labyrinth and directed back into the bearing housing. During operation, centrifugal force lifts the VBX ring away from contact with the stator to create a non-wearing permanent seal. When at rest, the Inpro/Seal VBX ring effectively seals the labyrinth – blocking condensation and other contaminants from entering the bearing housing. The Inpro/Seal Bearing Isolator provides permanent bearing protection for pumps, motors, gearboxes, pillow blocks and other rotating equipment.Ī two-part dynamic seal, the Inpro/Seal Bearing Isolator consists of a stator and rotor working in conjunction to form a non-contacting compound labyrinth seal with no wearing parts and ingress protection ratings up to IP66.
