Risks of using Non-OEM Parts

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
