Shell Cassida Fluid WG
High performance, synthetic gear lubricant for worm gear
boxes used on food manufacturing equipment
Shell Cassida Fluid WG 220, 320, 460 and 680 are high performance, anti-wear gear oils
for the lubrication of worm gears, highly loaded gears and applications where high
resistance to micro-pitting is needed, in food and beverage processing machinery.
They are based on a careful blend of synthetic fluids and selected additives chosen for their ability to meet
the stringent requirements of the food industry.
Registered by NSF (Class H1) for use where there is potential for incidental food contact. These Products
contain only substances permitted under US 21 CFR 178.3570, 178.3620 and 182 for use in lubricants with
incidental food contact. They also meet the former guidelines (1998) of the US Department of Agriculture for
Food Safety and Inspection Service (USDA) for H1.
Applications
Especially recommended for use in worm gears and
applications where excellent thermal stability is
required.
Lubrication of enclosed gear boxes used in the food
industry.
High load carrying capability, for extreme pressure
applications
Performance Features
High resistance to micro-pitting
Neutral odour and taste
High viscosity index: Maintains higher viscosities at
higher temperatures, giving thicker oil films under
difficult conditions.
Shell Cassida Fluid WG provides excellent thermal
stability, load carrying properties and corrosion
protection. Resistant to the formation of harmful
oxidation products.
Exceptional low friction providing efficient power
transmission. Measured worm gear efficiency is high
relative to other oils.
Water solubility makes Shell Cassida Fluid WG ideal
for use in situations where equipment gets routinely
cleaned before and after use and where some water
might penetrate into the lubricant.
Does NOT mix with mineral oils or PAO
Seal and Paint Compatibility
Compatible with most of the elastomers, gaskets and
seals normally used in food machinery lubrication
systems. Nitrile rubber (NBR), Fluoro-Silicone or VinylMethyl Polysiloxane (Q) are recommended especially
where high temperatures are involved. Polyurethane
based elastomers, leather, cork, asbestos paper and
board should be avoided. Note: see warning about seal
shrinkage in section on change-over procedures. Some
ordinary industrial paints soften in the presence of Shell
Cassida Fluid WG. Internal gearbox surfaces should
ideally be unpainted or coated with resistant material
such as two-part epoxy formulations.

Change over procedures
When changing form a lubricant based on mineral oil or
PAO, the following procedure must be followed:
The equipment should be at normal operating
temperature then the oil drained off as fully as possible.
Special attention should be paid to reservoirs, lines etc.
where oil may be trapped.
Then the system must be flushed with the new lubricant,
which should then be drained before re-filling with fresh,
new lubricant. Do not use Shell Cassida Flushing Fluid
for flushing a system prior to using Shell Cassida Fluid
WG.
Note: Seals previously exposed to mineral oils may
shrink when exposed to Shell Cassida Fluid WG. This
can result in oil leaks. It may therefore sometimes be
necessary to replace them.
Synthetic lubricants

animals or genetically modified organisms (GMO). Technical Data Sheet Shell Cassida Fluid WG
Shell Lubricants Page 2 of 2 FEBRUARY 2006
Does not contain any allergenic or intoleranceinducing substances as specified in Annex IIIa of EC
directive 203/98/EC
Suitable for use where vegetarian and ‘nut-free’ food
is prepared.
Biostatic; does not promote the growth of bacteria or
fungal organisms.
“Incidental Food contact”
Registered by NSF (Class H1) and meets the USDA H1
guidelines (1998) for lubricants for use where there is a
potential for incidental food contact.
Made only from substances permitted under the US FDA
Title 21 CFR 178.3570, 178.3620 and/or those
generally regarded as safe (US 21 CFR 182) for use in
food grade lubricants.
To comply with the requirements of US 21 CFR
178.3570, contact with food should be avoided where
possible. In the case of incidental food contact, the
concentration of this product in the food must not exceed
10 parts per million (10mg/kg of foodstuff).
In locations and/or applications where local legislation
does not specify maximum concentration limits, Shell
recommends that this same 10 ppm limit be observed, as
up to this concentration Shell Cassida Fluid WG will not
impart undesirable taste, odour or colour to food, nor
will cause adverse health effects.
Consistent with good manufacturing practice, use only
the amount necessary to achieve correct lubrication and
take appropriate corrective action should excessive
incidental contact with food be detected.
Health & Safety
Based on information available, Shell Cassida Fluid WG
is unlikely to present any significant health or safety
hazard when properly used in the recommended
application and good standards of industrial and
personal hygiene are maintained. As for all oils,
prolonged or repeated contact with the skin should be
avoided.
For further information refer to the appropriate Shell
Material Safety Data Sheet.
Oil condition during use
It is recommended that the condition of the oil and the
equipment be regularly checked to ensure safe
operation.
Protect the environment
Take used lubricants and empty packs to an authorised
collection point. Do not discharge into drains, soil or
water
Handling and storage
All food grade lubricants, such as Shell Cassida Fluid
WG, should be stored separately, out of direct sunlight
or other heat sources, from other lubricants, chemical
substances and foodstuffs. Store between 0°C and 40°C.
Provided that the product has been stored under these
conditions we recommend that the product be used
within 5 years from the date of manufacture. Consult
your local Shell Company for details.
Accept for use new Shell Cassida Fluid WG only if the
manufacturer's seal is intact.
Before opening the pack ensure the area around the
closure is clean. It is recommended that it be cleaned
with Shell Cassida Fluid PL and/or potable water and
then dried with a clean cloth before opening.
Record the date the seal was broken. To prevent product
contamination, always close the package after use. Upon
opening a pack, the product must be used within 2 years
(or within 5 years of date of manufacture, whichever is
the sooner).
