There are many Elastomers and Plastics that biodiesel and biodiesel processing degrade. Care should be taken when choosing parts for your system. Here is some information that we have put together on the compatibility of some of our items.
Please keep in mind that this information is designed to be used as a guide and that we leave it up to the end user to decide the suitability of our products for their application.
It is difficult to find compatibility information on Biodiesel. Most of our information below has been gathered from several different sources and may not apply to every biodiesel compound.
Materials that we have been able to confirm as being compatible with Biodiesel (Methyl Oleate) are as follows:
Glass filled Polypropylene
Materials that we know to not be compatible:
There are many things to consider when choosing the appropriate materials for your system. Because there are many types of biodiesel it is often necessary to test your materials with the particular type of biodiesel that you are producing.
The follow is a list of products that have been successfully used with Biodiesel.
For pumping biodiesel fuel
For transfer tubing
For quick disconnects fittings, CPC™ tells us that their glass filled Polypropylene fittings are what they recommend with FKM O-rings. They suggest their non-spill line. We do not stock any with the FKM O-rings, but we can order them in for you.
Nylon and Kynar fittings are both good choices for barbed or compression connectors and threaded fittings.
Note: People have been known to use PVC valves and fittings for biodiesel applications. We do not recommend the use of PVC since over time it will soften and weaken PVC which can cause leaks in your system. Because PVC is easy to acquire and often a much cheaper option then metal parts some people still choose to use it and just plan on replacing when they start to develop leaks.
Note: FKM or Viton is compatible with biodiesel; however, it is not compatible with sodium and potassium hydroxide which is often used in the processing of it.
The polyethylene cone bottom tanks that we distribute for Ace Rotomold are what are typically used for biodiesel processors. While these can be used for the processing, they are not recommended for storage. For storage many people use metal drums. The only tanks that we offer for storage are our Fuel and Oil tanks which are made of a special polyethylene resin that is designed to hold up to fuels.
Ryton® Body with PTFE vanes (90018 only)
Silver Star Explosion Proof Variable speed drum pump
Sandpiper® Metallic Pump series Aluminum and PTFE pumps (not available online)
Sandpiper® Air Operated Diaphragm Kynar and PTFE pumps
Portable Mixer with Retractable Blade (15242 has a explosion proof motor)
