Description:

We have IC4 make up pumps in the LDAR Program. These are monitored monthly; the sample results were over 10,000 ppm limit. Our only course of action was to replace the seals , only to have them fail again next month. The failure was due to the design of the pump, not the seals.The cost for continually replacing the seals was adding up with no results.

P2 Application:

We installed our first Patent Pending Bio Filter system in May 2006. The G4 Model filter scrubbed the Hydrocarbons and kept them from escaping to the atmosphere. The design of the Sundyne centrifugal pump has on 1/4"npt vent port which is where the method 21 test instrument sampled and always found it leaking over the 10,000 ppm limit. This port is now piped to the inlet connection of the Bio-Filter inlet case. The system has a built in liquid fluid barrier to force the vapors through the filter pillow and an outlet line to the sump tank for safety reasons in the event of a seal failure. This application of new technology is keeping the pumps in complience every month without a single failure (average readings are now under 100 ppm).

  • Total Cost Savings: $10,000.00

Details of Reductions

Additional Information :

We have since installed this filter on 17 more similar designed pumps, with the same outstanding results. I have submitted this application for best practice within our company. We have saved thousand of dollars in maintenance expenses and we are no longer replacing perfectly good parts trying to meet the required limitations. If this technology had not been found, we would have been forced to replace our pumps with new designed equipment at much higher cost to achieve the same goals.
