comes into contact with this material,
it is removed from the system.
The Parker filter cart uses two high
capacity ModuFlow™filters for long
element life and better system
protection. The first stage (inlet) filter
captures larger particles, while the
second stage (outlet) filter controls
finer particles or removes water. A
rugged industrial quality gear pump
gets the job done fast.
Using a Parker portable filter cart is
the most economical way to protect
your system from the harm that can be
caused by contamination.
Parker filter carts are the ideal
way to prefilter and transfer fluids
into reservoirs or to clean up existing
systems.
Fluid should always be filtered before
being put into use. New fluid is not
necessarily clean fluid. Most new
fluids (right out of the drum) are unfit
for use due to high initial
contamination levels. Contamination,
both particulate and water, may be
added to a new fluid during processing,
mixing, handling and storage.
Water is removed by installing
Par-Gel™ elements in the outlet filter.
Par-Gel™ elements are made from
a polymer which has an extremely
high affinity for free water. Once water

Assembly
1) Install hoses to inlet and outlet
filters by threading the hose end
with the straight thread “o”-ring
seal fitting into the filter flange.
2) Connect the PVC tube wands to
the swivel fitting on the hose end.
Whenever servicing the PVC tube
wand do not overtorque the metal
fittings going into the PVC coupling.
Overtorque will result in cracking the
coupling. Generally, 1/4 turn beyond
handtight is sufficient.
Operating Instructions
1) Insert the inlet wand assembly
into the supply fluid receptacle
(drum/reservoir). The “RF”. filter
is the inlet filter.
2) Insert the outlet wand assembly
into the clean fluid receptacle
(drum/reservoir). The “CF” fIlter
is the outlet filter.
Caution:
Do not kink the hose assemblies,
this may result in excessive
vacuum or pressure at the pump.
3) Verify that the ON/OFF switch is
OFF and plug the cord into a 115V
10A grounded outlet (3 wire).
4) Turn switch to ON position and
check outlet wand for oil flow.
Allow 30 to 60 seconds for filters
to fill with oil. If repeated attempts
to obtain oil flow fail, check pump
inlet fittings for tightness, remove
inlet filter access cover and verify
the cover sealing “o”-ring is in
place. For very viscous fluids it
may be necessary to pour 1 or 2
quarts of fluid into the “RF” inlet
filter housing to prime pump
initially.
5) The condition of the filter
element should be monitored by
observing the cleanliness
indicator on the discharge
filter. When the Indicator is in the
CHANGE position, both inlet and
outlet filter elements MUST be
replaced to prevent fluid from
going into bypass in the filters.
6) The inlet filter Is provided with a
3PSI bypass spring, and prevents
the pump from cavitating If the
element is not changed. The outlet
filter is provided with a 25PSl
bypass spring to prevent excessive
pressure which may be harmful to
personnel or to the filter cart.
Warning:
The filter bypass spring acts as a
relief valve for the pump. Do not
restrict the discharge hose with
a shut-off valve which will defeat
the function of the bypass valve,
causing excessive pressure, which
may be harmful to personnel or to
the filter cart.
7) The cleanliness indicator works
on differential pressure and
will indicate the condition of the
element (CLEAN, CHANGE, or
BYPASS).
NOTE:
The filter cart must be in
operation for the indicator
to read properly.
Maintenance
Instructions
1) Turn switch to OFF position and
unplug cord from electrical outlet.
2) Remove tube wands from oil to
prevent siphoning.
3) Loosen hex head screws on
filter cover. Turn cover to clear
screws, remove cover.
4) Pull flow diverter assembly
from the filter head. Filter
element will follow the diverter.
a) Replace the cellulose,
synthetic or Microglass II
elements. Verify replacement.
b) Wire mesh elements can be
cleaned. Ultrasonic cleaners
provide best results.
5) Install element on flow diverter
and reinstall in filter housing.
Make sure diverter “o”-rings seat
properly into the head.
6) Check to be sure that the notch
on the flow diverter lines up with
the notch in the head.
7) Inspect the cover “o”-ring and
replace if necessary.
8) Replace cover and tighten hex
head screws until they are snug.
Do not over-torque these screws.
Do not interchange the inlet filter
cover with the outlet filter cover.
(The inlet filter has a “RF” prefix,
the outlet filter has a “CF” prefix).
Problem Cause Solution
Does not start. ON/OFF switch. Turn switch ON, replace switch if defective.
No electrical power. Plug in cart.
Defective motor. Replace.
Filter housing not filled with oil. Allow pump to run 30 to 60 seconds.
Suction leak. Check tightness of inlet fittings.
Check “o”-ring in inlet filter cover for nicks.
Kink or restriction in inlet hose.
Add 1 or 2 quarts of oil to inlet filter.
Defective pump. Replace pump.
Element dirty.
Replace or clean elements (both filters).
Oil extremely cold or viscous. Change element to coarser micron rating.

Portable Filtration System
Guardian®
Parker Hannifin Corporation
Hydraulic Filter Division
Metamora, OH
The Guardian portable filtration system is a unique
pump/motor/filter combination designed for conditioning
and transferring petroleum-based and water emulsion
fluids. It protects your system from contamination added
with new fluid because new fluid is not necessarily clean
fluid. Most new fluids right out of the drum are unfit for use
due to high initial concentrations of contaminants.
Contamination may be added to a new fluid during
processing, mixing, handling, and storage.
The Guardian also circulates and “polishes” fluid in your
existing systems to reduce the contamination to an
acceptable level.
There are literally hundreds of applications that the
Guardian is suited for, with more being discovered each day.
If your system is sensitive to the harmful effects of
contamination, then the Guardian may be ideal for you.

Principles of Operation
Contaminated oil is drawn into the Parker Portable
Purification System by a vacuum of 25 In/Hg. The oil
passes through the in-line low watt density heater
where the oil is heated to an optimum temperature of
150° F (66°C).
The oil then enters the distillation column where
it is exposed to the vacuum through the use of spe-
cial dispersal elements. This increases the exposed
surface area of the oil and converts the water to vapor
form, which is then drawn through the condenser by
the vacuum pump.
The water-free oil falls to the bottom of the column and
is removed by a heavy duty lube oil pump. This pump
forces the dry oil through a final particulate removal
filter. Clean oil passes out of the unit, back to the
reservoir — and into the system.
Effects of Water Contamination
Water is one of the most common contaminants in
a fluid system and one of the most damaging. When
water contaminates a system, it can cause serious
problems such as:
NCorrosion by etching metal
NFluid breakdown, reduction
of lubricating properties,
additive precipitation, and
oil oxidation
NReduced dielectric strength
NAbrasive wear in
hydraulic components
Free water occurs when oil becomes saturated and
cannot hold any more water. This water is usually seen
as cloudy oil or puddles of water at the bottom of an oil
reservoir. Water which is absorbed into the oil is called
dissolved water. At higher temperatures, oil has the
ability to hold more water in the dissolved stage due
to the expansion of oil molecules. As the oil cools, this
ability reverses and free water will appear where not
visible before. In addition to temperature, fluid type
also determines the saturation point for your system
(see chart above).

PVS (Vacuum Dehydration)
Compared to Other Technologies
Centrifuge units– Removes free water only; has difficulty
breaking stable emulsions; larger envelope dimensions but
lower flows; higher initial and operating costs.
Desiccant units– Have limited water removal
capability due to absorbing material; only removes air
ingressed particles; expensive compared to the volume of
water removed.
Coalescer units– Removes free water only; has difficulty
breaking stable emulsions; does not work well in viscous
fluids (>100 sus); much larger in size compared to PVS.
