Water Removal from Hydraulic and Lube Oils

Vacuum Dehydration Purifiers

Water, gas and solid contaminants in hydraulic and lubricating fluids have a detrimental affect on system performance. In order to maintain the health of these systems, free and dissolved water and gases should be removed.

Pall’s vacuum dehydration purifiers are designed to remove 100% of the free gases and water (under steady state conditions), and up to 80% of the dissolved gases and water. Our purifiers are also designed to remove solid contaminants, utilizing high efficiency filters with a particle removal efficiency rating of 99.9% at the 3 micron size range.


Coolant and Process Applications

Melt Blown Filter Elements

Recognizing that different applications have different contamination loading and debris profiles, Pall offers a broad range of melt blown filter products to meet varying process requirements in lubrication, coolant, and other process applications. Pall’s family of melt blown filter elements are made using continuously extruded fine fibers to form a highly porous, high strength filter matrix with superior on-stream service life, low pressure drops, and consistent contamination removal performance.


Incoming Water

Pall Aria Membrane Systems

Pall Aria water treatment systems are specifically designed to produce potable drinking water that meets today’s stringent quality standards. Pall Aria systems use uniquely designed hollow fiber membrane modules to remove turbidity, bacteria, cysts and oocysts, iron, and manganese from ground and surface waters, as well as secondary wastewater effluent streams. 


Wastewater & Alkali Solutions

Ceramic Membrane Systems

Pall’s ceramic membrane systems are used to treat spent oil emulsions and have proven to be effective in caustic degreasing in the metals industry. With this novel approach to treatment, fewer chemicals are used and discharge waste and sludge are minimized. Pall’s ceramic membranes and systems offer superior resistance to thermal and chemical degradation when facing water with extremes in pH and temperature. The membranes can easily be cleaned and regenerated providing superior service life and economy for the customer.


Rolling Mill Coolant Systems

Microfiltration (MF) Systems

Pall offers a range of microfiltration systems which are used to remove suspended solids from highly contaminated fluid streams. The robust nature of our hollow fiber membrane technology allows these systems to manage highly contaminated feed streams. This technology offers a new approach for treating many process coolant streams found in aluminum, stainless steel, and copper rolling mills.


Contamination Monitoring


Particulate Contamination Monitors

Obtaining accurate and reliable fluid cleanliness data quickly in order to detect abnormal contamination levels is a key factor in ensuring the required cleanliness for fluid systems. Pall provides portable devices that give plant operators the ability to measure the cleanliness of fluids simply, quickly, and reliably. Pall offers two types of cleanliness monitors — mesh blockage for emulsions and aqueous fluids and laser light particle counters for mineral, synthetic- and hydrocarbon-based fluids.


Water Sensors

Hydraulic or lube systems should be operated with minimal concentrations of water. Pall’s water sensors detect water in solution within the fluid, displayed as a percentage of the fluid saturation level at the measurement temperature, or expressed as parts per million (PPM), specific to each brand of fluid. Options include a handheld unit for a ‘point-intime’ reading or a permanent unit which can provide continuous or timed monitoring.


Pall Fluid Analysis Services

Pall offers multiple levels of fluid analysis services to meet the varying needs of our customers. Level I fluid analysis uses Pall’s portable fluid contamination analysis kit and fluid contamination comparator tool to provide rapid, on-site, real-time assessment of the health of lubricating and hydraulic systems. With this service, we provide approximate fluid contamination levels as well as particle size distribution and contaminant identification. Level II services provide quantitative fluid contamination analysis and can be custom tailored to meet individual plant requirements. Pall fluid analysis programs* can be a highly effective tool to monitor the health of lubricating and hydraulic systems.
