Mide manufactures and installs hydrogel activated bulkhead shaft seals.
The seals can operate at depths over 35 ft and with air pressure differentials across the seal exceeding 0.5 psid.
During qualification testing it was demonstrated that, when flooded for 14 days, the seals can limit the leak rate to less than 1 US pint/minute while the shaft is spinning at maximum RPMs.
The seals are non-rotating and can be installed with shaft/bulkhead misalignment angles exceeding 0.5 degrees. The seals are shock and vibration qualified as per MIL-S-901D and MIL-STD-167-1A.
It is anticipated that by October 2009, Midé will have qualified seals with diameters ranging from 10” to 30”.
