Calculate Potential Seal Savings

Save costs with Kalrez® sealing parts

Use the calculator below to estimate cost savings by installing Kalrez® perfluoroelastomer parts.

Kalrez® seals extend mean time between repair (MTBR), which reduces both scheduled and unscheduled downtime, associated costs, and results in significant cost reductions and/or cost avoidance.

Current Elastomer Material
Kalrez® Perfluoroelastomer Parts
Cost of new mechanical sealmore info
Enter a numeric current seal cost.
Enter a numeric Kalrez® seal cost.
Enter the cost for a new mechanical seal outfitted with the current elastomer O-rings and then input the cost of a seal outfitted with Kalrez® perfluoroelastomer O-rings.
Cost to repair sealmore info
Enter a numeric repair cost.
Enter the cost of a repaired mechanical seal utilizing the current elastomer O-rings. This is typically 50% of the cost of a new seal.
Number of pumpsmore info
Enter the number of pumps.
Enter the number of pumps in this service.
Downtime cost of seal failure (avg)more info
Enter a numeric downtime cost.
Enter an estimate of the cost when a pump goes down. This would include items such as: maintenance costs (pump removal and repair), lost production expense, spill cleanup, off spec product disposal, inability to meet customer orders, etc. In a typical chemical plant this cost may be $5000 or more.
Mean time between repairs (in months)more info
Enter numeric prior mean time between repairs (in months).
Enter numeric new mean time between repairs (in months).
Enter the Mean Time Between Repair (MTBR) in months for the current mechanical seal. Next, enter the expected (or known) MTBR for the mechanical seal with Kalrez® O-rings.
Expected equipment lifetime (in years)more info
Enter the numeric expected equipment lifetime (in years).
Enter the expected lifetime of the process equipment. For a pump, this may be on the order of 25 years.

Enter a numeric downtime cost.
Enter an estimate of the cost when seal failure occurs. This would include items such as: maintenance costs (pump removal and repair), lost production expense, spill cleanup, off spec product disposal, inability to meet customer orders, etc. In a typical chemical plant this cost may be $2000 or more.

*Downtime cost generally ranges between US$ 1000 and 3000. The above example was kept rather conservative. With higher downtime cost, total system cost savings could be even higher. The example covers 15 to 30 minutes to replace O-ring and rebuild coupling, or to install a spare coupling. Of course, each plant has its unique replacement rate and downtime cost to be considered for this cost calculation.

Explanations to above chart:
  • The initial seal price of the Kalrez® O-ring is estimated at 50 times higher than the current elastomer O-ring. This is an indicative number, if you would like to get a quote for a Kalrez® part, please contact us.
  • The installation (100) and the downtime cost (1000) related to seal failure are the same for both O-rings.
  • The lifetime of the Kalrez® O-ring is twice as long (36 months) as the lifetime of the current O-ring (18 months). Thus, for a timeframe of 3 years, the current O-ring will need to be replaced once, whereas the Kalrez® part does not need replacing. The resulting total cost (total downtime cost and cost for installations) related to the number of seal replacements is also higher for the current O-ring material used.
  • Conclusion: The lifetime of the O-ring has a dramatic impact on total system cost. In this example, even for only one O-ring installed, savings of 87% could be realized with the use of a Kalrez® O-ring.
