Contamination Fundamentals

Cost Savings through Fluid Service!• Effective filtration practices and in-depth monitoringand evaluation of fluid attribute changes in hydraulicand lubrication systems, provides alerts that lead tocorrective actions that will prevent breakdowns andincrease the life expectancy of important andexpensive hydraulic and lube system components .

• The high costs of component repair and systemdowntime can be kept to a minimum through a fluidservice program that includes using and maintainingthe proper system filtration and monitor ing equipment.

• Leaving sample bottles open too long

• Using previously contaminated bottles

• Unaware of system operation immediately beforesampling resulting in inaccurate analysis andconclusions.

• Improper handling causing contamination from hands

• Failure to flush sampling ports and lines before sampling

Note: Such errors are likely to result in higher contamination readings than

actual.

Beta Ratio remains at a relatively constant level at high pressure drops beyondnormal element operating ranges with high beta stability.

Beta 100 Stability = 210 psi means that:

Beta Ratio at the rated micron will not drop below Beta Ratio = 100 until 210 PSID

Beta Stability ISO 16889: 1999

Point of element failure

High ß x-Values / High ß x-Value Stabili ty

Poor Beta Stability Causes a loss ofadequate protection from the point that Beta drops

below manufacturer’s published beta specification before the end of element life.

• Significant loss of fil ter efficiency before the end ofelement life

• Loss of equipment through loss of protection

• Increased wear and component failures• Increased downtime• Decrease in Customer Satisfaction

• Decrease in downtime when indicator is uti lized for change-out indication(Less Element Changes)

• Decrease in replacement element costs (longer lasting-util izing full element capacity)

• Decrease in maintenance/labor costs

Surface Filtration Depth FiltrationWith surface media (paper, metals, polyester) there isno mechanism to hold di rt in place when placing theelement into a dynamic system with high veloci ty flow

changes and a reverse flow surgin g environment.

With depth media as show n above, the particles enterthe media and work their way down into th e pores andpassages to become entrained. This provides themechanism that holds these particles in place whenused in dynamic flow s urging s ystems.

The design and operation of a

Hydraulics System

• Assess system requirements • Recommend optimum components

for performance and longevity • Monitor & Maintain fluid

characteristics, cleanliness and watercontent

Assess 1. Determine TCL (target cleanliness level) Based on

• system components• system pressure & environmental conditions

Use this guidelines document found on our websiteIn the Brochures section

Assess 2. Determine Current Conditions

• particle contamination levels• water content• fluid health (ageing/effectiveness)• fluid sampling changes over time

Assess 2. Evaluate Current Protection in Place

• to account for ALL sources of contamination

Assess 2. Evaluate Current Protection in Place

• pressure filters• return line filters• offline filtration loops

• breathers-high integrity and desiccant types• new oil protection – treatment, transfer, polishing• monitoring (sampling)/change-out schedule

E = Pressure AND Return Filter AND Re-circulating Loop

Recommend Filtration Upgrades

Recommend Filtration Upgrades 1. Betafit Elements

• High ß x-values• High ß x-value stability

• High dirt holding capacity• Low long term pressure drop• High collapse stability• High flow fatigue stability• Wide fluid compatibility

Recommend Filtration Upgrades 2. Addition of Offline Filtration Loops

Vacuum Dehydrator when high water orgas content is present

Off line loop membraneFiltration –Used for solid particulate intransfer and tank kidney loops

Filter coolers when heat is a problem

Recommend Filtration Upgrades 3. Addition and replacement of high

performance breathers

Breathers Wide variety including:- desiccant for water vapor removal- spin-on- with filler baskets

Monitor & Maintain1. Contamination Monitoring Devices• Portable & Online• Water Content Sensors

FCU (Portable)Perfect for plants withmany small machines

CS (Permanent)Perfect for larger, critical systemswhere constant, monitoring is required

AS (AquaSensor)Water content sensor

2. Supplemental Monitoring Techniques• Regular Fluid Sampling & Analysis

Fluid Sampling Kits Provides information about more than contamination:- additive depletion- contamination- water content

- viscosity- wear metals- trending from periodic sampling

Monitor & Maintain

Leads to predictive maintenance decisions

eliminating unplanned shutdowns

3. Portable Offl ine and Fluid Handling Filtration Loops• Can be used on multiple machines if contamination

levels unexpectedly rise
