LUBRICATION STRATEGIES

attractant and can be transferred
unwittingly if the cart and its components are not kept scrupulously clean.
S Unless specified, most filter carts are
sold with open-end transfer wands
fitted to the delivery and suction hose
ends designed to slide easily into the
reservoir openings of the donor and
recipient reservoirs. In a program
designed to filter contaminants
from the oil, this type of delivery
fitting can allow moisture and dirt
contamination into the respective
reservoirs during the transfer
process. To combat this, and ensure a
contamination-free transfer process,
fit the filter cart delivery/return hose
ends and reservoir fill/drain ports
with quick-lock-style couplings. As
the reservoir is now airtight, it will
also require a quality desiccant-style
breather to be fitted and, in the case
of larger capacity reservoir, a closedloop expansion tank.
S Specify kink-resistant flexible suction
and delivery hose to prevent pump
cavitation. Clear hoses allow a visual
reference of the oil flowing through
the lines.
S The cart's electric motor will require
access to electricity. Ensure that an
electrical outlet is within easy reach
of the unit's electrical cord. If the
cord is short in length, consider
mounting a retractable electrical cord
caddy on the unit with enough cord
length to reach the nearest electrical
outlet.
S Paint a lined box similar to a laydown area as close as possible to the
oil reservoir that's to be serviced. This
allows a cart to be positioned and
used quickly without obstruction,
and within reach of its hose and
wand assemblies.
S Place the cart on a preventivemaintenance (PM) check program
prior to every use to ensure the unit's
filters don't go into bypass mode
from being too dirty. MT

Reduce Maintenance
Cost by up to 40%

Keeping oil clean - It's your best insurance!
1

Clean incoming oil - because new is NOT clean oil

2

Keep oil clean - remove solids AND moisture

Keep your first fill from starting things off on a dirty foot. Our
systems remove impurities in your new oil. These contaminants
are the seeds of increased maintenance costs in the form of
downtime, wear, and repair.

A Harvard Filtration system on your machinery will
keep your investment clean and operating at its peak
performance. In hydraulic systems, 70-80% of failures
are due to contamination. The Harvard Constant
Contamination ControlĀ® keeps moisture and contaminants
from accumulating in your oil. This prevents premature
wear, and reduces costs. Let us show you how one
company reduced their maintenance costs by 40%.
