Wilfley Centrifugal Pumps Save Water Mechanical Seals Compression Packing

Mechanical seals and compression packing waste millions of gallons of water every year


Wilfley sealing technology provides leak free operation at all times without requiring the type of flush systems and expensive operating costs that are needed for conventional sealing systems like mechanical seals and compression packing. This might not seem very important until you look at it from a larger scale… the yearly savings can be astounding!

Notes on Charts:

  • Charts are based on a pump running for 24 hours a day, 365 days a year. Solution contains 10-20% fine solids by weight.
  • Data is based on best case scenario.
  • Mechanical seal flush rate data based on 1 USGPM per inch of shaft sleeve diameter.
  • Packing data is based on a “full flush” configuration with 60% of the flush water entering the process.
  • Evaporating cost data based on the Fluid Sealing Association Life-Cycle Cost Estimator.
  • Evaporating cost based on $0.10 per kWh.
  • 1 drop of fluid = 0.0084 fl oz (0.25 ml).
