Offline Hydraulic Filtration Systems

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.

The bottom line - fluid should always be filtered before being put into use. The Parker Guardian Portable Filtration System offers a unique pump/motor/filter combination, designed for conditioning and transferring petroleum-based and water emulsion fluids. This unit protects systems from contamination added by new fluid. The Guardian also circulates and “polishes” existing fluid in systems to reduce the contamination to an acceptable level.

The Guardian is lightweight, compact, and hand-held, making it easy to carry and reach difficult areas. Fitting easily on a 55 gallon drum, this convenient unit and only requires one person to operate – saving labor costs.

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.

The Parker SMR Series Submicronic Removal Fluid Purification System is the smart purification solution for fluid flow around 10 GPM (38 LPM). The SMR contains Parker patented Balanced Charge Agglomeration (BCA™) technology, which maintains hydraulic and lubricating fluids in optimum condition while preventing/removing the build-up of sludge and varnish.

Balanced Charge Agglomeration (BCA™) technology does not remove water, however with the removal of thousands of submicron particles; the majority of sites where water can readily attach are mitigated. Water is more easily separated and removed, improving demulsibility, or the ability to release water.   
Demulsibility is an important factor to consider when hydraulic equipment operates in an atmosphere that is wet or humid. Food-processing operations, such as cooking oil, for example, provide significant exposure to water-based process fluids.

Because oil is hygroscopic, or able to absorb water, it is quite easy for water to saturate the oil. Water enters through any number of ways, and must be removed in order to protect a system’s operation. When demulsibility is diminished, the oil will become contaminated by the water, causing quick wear to the system’s components.

Maintaining a hydraulic system’s oil cleanliness level will increase the life of the critical wear components, and reduce system downtime. Portable purification units are ideal for systems in applications demanding on-site decontamination. With several models to choose from, the Parker SMR Series is an ideal solution for many hydraulic system’s needs.

This system is available in a PLC or simplified control version. Please contact a Parker Representative for assistance.

Balanced Charge Agglomeration (BCA™) - How the Technology Works:
Contaminated fluid is passed over a series of high-voltage electrodes, inducing a charge on the submicron particles of (+) and (-), then the particles continue down separate paths. (Note that particulate contamination as small as 0.1 microns are able to amass this charge). Oil, a non-conducting fluid, remains neutral. The two oppositely charged particle fluid streams are then re-combined. The oppositely charged particles are then mixed and are attracted to each other, forming larger particle clusters, growing in size as they agglomerate, or join together. Submicron particles grow into multiple micron-sized particle clusters. Once larger in size, the particle clusters are more efficiently filtered. Finally, the particle clusters are then sent through the system’s high efficiency filter to be removed.

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 many serious problems such as: corrosion, fluid breakdown, reduction of lubricating properties, additive precipitation, oil oxidation, reduced dielectric strength, and abrasive wear in hydraulic components.

Whether dissolved water (water which is absorbed into the oil) or free water (occurring when oil is too saturated* to hold any more water), solid particulate, or air/gasses, contaminated oil can be purified on-site using Parker's PVS Series Portable Purification System.

* Please Note that Temperature and Fluid type determines the saturation point for your
system (Please Refer to Brochure).

Maintaining a hydraulic system's oil cleanliness level will increase the life of the critical wear components, and reduce system downtime. Portable purification units are ideal for systems in applications demanding on-site decontamination. With several models to choose from, the Parker PVS Series is an ideal solution for many hydraulic system's needs.

Principles of Operation:
Contaminated oil is drawn into the Parker PVS Series Portable Purification System by a vacuum. The contaminated oil is then subjected to optimum vacuum, temperature, and increased surface area exposure. The optimum temperature is achieved using an in-line, low watt density heater. Afterward, the oil enters the distillation column, where it is exposed to the vacuum through the use of special dispersal elements, achieving the increased surface area exposure. This process converts water into water vapor, which is then drawn through the condenser by the vacuum pump.
The water-free oil falls to the bottom of the distillation 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 then back into the system.

Why PVS (Vacuum Dehydration) Techonology Out-performs 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.

The AFS is the ideal way to prefilter and transfer fluids, on the ground or in the air.
Fluid should always be filtered prior to use. New fluid is not necessarily clean fluid. Most new fluids (directly from the container) are unfit for use, due to high initial contamination levels. Contamination, both particulate and water, may be introduced to a new fluid during processing, mixing, handling and storage.
The AFS uses a high capacity ModuFlow™ Plus filter for long element life and optimum filtration. The single element package provides a high level of filtration performance in a compact size. Free water is controlled by utilizing Parker’s Par-Gel™ element. Par-Gel™ elements have a very high affinity for free water.
Designed with functionality, space and durability in mind the AFS comes standard with a rated lifting eye. The optimized design and rugged steel construction allow service personnel access to the critical hydraulic systems through passageways as small as 12” x 16”.
The use of a Parker portable filtration system is the most efficient and economical way to extend fluid life and protect critical system components from harmful contaminants.
