Risks of using Non-OEM Parts

Alfa Laval has a large Canadian inventory of heat exchanger gaskets and plates. Alfa Laval manufactures OEM-specified heat exchanger gaskets in custom gasket materials, FDA-approved, NBR and EPDM. Using non-OEM parts introduces risks into your business that can be costly over time. Order parts, or, send us your serial number and questions via:

After extensive testing of genuine Alfa Laval parts vs. non-OEM parts, consider these flaws we documented in non-OEM pump seals:

  • Low steel grade - lower steel grade found in static face holder
  • RISK: High potential for seizure when seal is being fitted into the pump

  • Wrong silicon carbide - an inferior silicon carbide found in static face inserts
  • RISK: Unwanted chemical reactions and part corrosion can occur

  • Using gasket material for an O-ring - a non-OEM O-ring "re-design" uses PTFE gasket material instead of standard O-ring material
  • RISK: The PTFE gasket material in an O-ring will result in O-ring compression, and eventually cause a leak

  • Incorrectly sized O-ring - a non-OEM manufacturer's O-ring cross-section measured 3.41-3.46 mm below tolerance
  • RISK: The poor O-ring seal can cause excessive leakage

  • Inconsistent coil spring diameter - the coil spring inner diameter was too tight in one or more areas
  • RISK: Excessive spring stress, resulting in leakage
