Filled Kalsi Seal™ Sizes
Filled Kalsi Seals™ were developed to retain lubricant in lower pressure, higher speed non-abrasive applications. The C-shaped construction of the shell allows the use of a low modulus silicone energizer that minimizes contact pressure at the seal-to-shaft interface. As with other Kalsi-brand rotary shaft seals, the Filled Kalsi Seal incorporates hydrodynamic waves that cause the seal to hydroplane on a film of lubricant when rotation occurs. This combination of features reduces running torque and seal-generated heat significantly, compared to single material Kalsi Seals.
Additional sizes can be furnished, subject to a one-time tooling charge to help to defray associated engineering, machining and set-up expenses. Seal purchase orders and requests for quote should be sent to the attention of Seal Sales via e-mail, or by fax at 281-240-0255.
