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
