VSG 'The Green Grease'
VSG 'The Green Grease' Now with Liners
Many locations have restrictions on how much residual grease can be left in used steel kegs and drums when these are being sent for disposal. This has been a pain and VSG grease has characteristics that are good in bearings but which can make cleaning the containers more difficult.
At the request of users all VSG steel kegs and drums now have a disposable flexible plastic liner. This is made of LDPE which can be recycled where allowed.
The use of a flexible liner makes it much easier to get out the last bit of grease and to add it to the new container as well as to be able to quickly clean out the containers for reuse, recycling or disposal.
As a caution to reduce the chances of the liner being pulled down by the follower plate used with grease pumps, it is suggested that the loose end of the liner at the top be taped to the container.

Question & Answers
1. What's special about VSG grease?
First it is mainly canola oil which is a natural renewable resource. Canola oils
are also low in toxicity with many being food grade for cooking oils and they
also tend to be readily biodegradable. Secondly, the grease thickener used is
relatively benign and has both inherent corrosion protecting capabilities and
extreme pressure resistance. Thirdly, the combination of these two offer a
grease that is 'green' and yet outperforms many mineral oil based products.
Some users have found that much less if required so that this is an added
2. Who's using it?
Users include Arizona Public Service, BC Hydro, Bureau of Reclamation, City of
Seattle, Eastern Ontario Power, Hydro Quebec, Churchill Falls (Labrador) Corp.,
Landsvirkjun (Iceland), Manitoba Hydro, Newfoundland and Labrador Power,
Ontario Power Generation, Orillia Power Generation Corp., Ottawa City Center,
Synex Wolverine LLC and TVA.
3. How does it perform?
VSG generally provides much better corrosion protection and wear resistance
while at the same time being more resistant to grease line plugging. VSG has
excellent pumpability at low temperatures and yet also stiffens up in contact
with water so it gets to the bearings and stays there better.
4. Who has tested it?
VSG has been independently tested by a number of utilities and by outside
organisations. This data is available in most cases and there are links on the
website to Bureau testing.
5. Is it compatible with our current grease?
The calcium sulphonate thickener is compatible with many of the lithium and
calcium greases being used for wicket gates. Data is available for the other
types and at the worst an intermediate grease has to be used for a short period
of time. But this has not been necessary yet. We do not recommend purging the
6. It costs more so is it worth it?
The components of VSG are more expensive and it is still a specialty product
with low volumes. However, as it becomes more popular some costs will come
down. In any case the amount of grease being used for a unit is seldom more
that a drum per year so the incremental cost should be less than $1,000. Given
the performance benefits and the high costs when dealing with regulators,
cottage owners and the like it can be well worth it. One station ended up using
42 times less grease so they saved big time.
