High Velocity Flush of Hydraulic Power Units

July 6, 2015

In the fall, PFPUSA had a customer call in to rent one of our Hydraulic Flushing Skids to flush a hydraulic system.  Their client had four old hydraulic power units (HPU)s that needed to rebuilt and flushed.

The hydraulic power units are a critical piece of equipment in the production process. The units supply power to the friction welders, which build the drive shafts. Needless to say, the HPUs play an important role in the production process.

The problem was that the units were running extremely hot, causing the company to make repairs frequently, sometimes daily. This lead to costly downtime and required the HPUs to be repaired immediately.

With a quick turnaround required, PFP shipped a 75 GPM Flushing Skid to flush the hydraulic lines and steel pipe fittings. By incorporating our Absolute Rated Microglass Filter Cartridges, the customer was able to achieve their target ISO code in a timely manner.

PODS In addition to the flushing skid, we provided our Portable Online Diagnostic System (PODs) in order to verify that the target ISO Code was achieved. Utilizing the PODs unit allowed our customer to determine when they achieved their target ISO Code on-site. No need to send an oil sample out to be tested.

The end result was four completely rebuilt and flushed Hydraulic Power Units and ultimately a happy customer!

High Flow, Clay Treater, and Coalescer Separator for NGL Application

Particulate Filter, Clay Treater, and Coalescer/Separator for NGL Application

A customer of ours was commissioning a new NGL distribution line. After gaining an accurate understanding of the application and quality goals, I was able to specify and deliver the appropriate filter vessels and elements within a few days. The most difficult challenge for our customer was time, or a lack there of. The immediate demand to provide product required a solution…FAST!

An additional challenge was a higher than standard design pressure of 285 PSIG. Fortunately, PFP maintains a significant rental fleet ranging from portable hydraulic filter carts to high flow pipeline filter vessels.

To guarantee the delivery of high quality product, a three-stage system with specific filtration technology was required to protect from potential contaminants…

  1. High Flow, Clay Treater, and Coalescer Separator Installed at Customer Location

    Particulate Filter, Clay Treater, and Coalescer/Separator Installed at Customer Location

    Particulate Filter: Removal hard particulate contamination such as pipe scale and dirt

  2. Coalescer/Separator: Aids is the coalescing and removal of water droplets
  3. Clay Treater: Absorption of chemical contaminates such as drag reducers, color bodies and surfactants.

Currently the system is operating perfectly and will continue to achieve quality goals until we build and ship the brand new system!

Call us to discuss how we can help you achieve and maintain your high quality product goals!

Heavy Equipment Service Center – Oil Cleanliness

May 5, 2015

LSF Filter UnitsAchieving target oil cleanliness levels when maintaining and repairing heavy equipment is critical to maximizing component life.

Recently we developed a specific plan and provided the filtration components to allow a local company to achieve their oil quality goals throughout the entire facility.

LargHydraulic Cartridge Housingse cartridge filter housings were provided to not only filter inbound oil, but also to provide kidney-loop or “multi-pass” capabilities in each oil storage reservoir. We then provided point-of-use filter housings at each hose reel and dispensing point throughout the plant. This combination ensures that oil will be filtered ever time it is transferred.

Adequately sized filters constructed with high efficiency, “absolute rated” filter media will provide significant dirt holding capacity, as well as, target ISO Cleanliness Codes. In addition, differential pressure indicators and electrical connections were provided to ensure filters will be changed-out as efficiently as possible, providing an even greater cost savings.

Give us a call at 888.679.6645 to discuss how we can help you improve your oil quality and maximize your equipment life.

How to Determine Correct Media Size for Achieving Target ISO 4406

January 21, 2015

ISO 4406 Cleanliness ChartOur sales manager forwarded me an email the other day from a researcher at a university who was confused about how to select the proper size of filter media in order to achieve a certain level of cleanliness according to the ISO 4406 standard. I proceeded to explain the following to him.

Referencing the document in question, “Understanding ISO Codes” (PDF), on the second page, the column labelled “Media” describes the recommended pore size of the corresponding filter media necessary in order to achieve the ISO code listed in the column to the left of the media size.

Please note that the examples listed are for systems using petroleum-based fluids per ISO 4406:1999, and for the following particle sizes:

4μ[c] / 6μ[c] / 14μ[c] (where each size corresponds to an ISO code number)

For example, in the chart you can see that for a servo valve with fluid operating up to 3000 PSI, the recommended target ISO cleanliness code is 16/14/11 and, in order to achieve this ISO code, the corresponding recommended media pore size is 5 micron (using an older testing method with a “beta[c] ratio” of 1000) and 3 micron (using the new testing method with a “beta ratio” of 200).

The “beta ratio” is the ratio between the number of particles per unit volume above a specific size in the suspension upstream of the filter to the same parameter in the flow downstream of the filter. The beta ratio of any particular filter is determined in a special test rig that enables accurate particle counting in its upstream and downstream flow regions. This simple ratio can be described by the following formula:

βx = Nu / Nd

where: “x” is the beta ratio for particles larger than x μm, “Nu” is the number of particles per unit volume larger then x μm upstream, and “Nd” is the number of particles per unit volume larger then x μm downstream. The higher the value of the beta ratio, the more particles of the specified size (or greater) are retained in the filter.

One insight that should be noted is that the filter efficiency (in percentage) at any particle size can then be determined directly from the beta ratio by using the following formula:

Ex (%) = 100 (βx – 1)/βx

For example, as mentioned in “Understanding ISO Codes“, a beta ratio of 1000 equates to a filtration efficiency of 99.9%:

Ex = 100 (1000-1)/1000 = 99.9%

and a beta ratio of 200 equates to a filtration efficiency of 99.5% efficiency.

Does this help you to understand better how to select filter media to achieve oil cleanliness?

Chemical Company Conquers Contamination of Lube Oil Reservoir

March 5, 2014

PFP's SFC spin-on filter cart for hydraulic oilI called on Brian one day, plant engineer at a chemical company on the east coast that manufactures adhesives for industrial manufacturers and end users. Unfortunately water and particulate had contaminated the lube oil system of multiple heavy machines that they operated. It appeared that the contamination was coming from a poorly sealed oil reservoir that was located outside of the facility, exposed to the natural elements of the four seasons. The contamination became a major issue because it was causing the failure of various servo-valves, thus shutting down their production lines, a major business disaster. They really needed a quick way to filter the lube oil without spending too much time or money in the process. I offered to visit them on site to see if one of our rental filter units could help them out.

During the time that I spent visiting Brian at the plant I discussed with him how exactly the lube oil system worked. We then determined which were the most critical mechanical components that come in contact with the lubricating oil. This allowed us to establish a base target ISO 4406 cleanliness code. We determined the proper flow rate to create a kidney loop for the oil reservoir. I also recommended that the they change to desiccant breathers on their reservoir and that they add better seals. Based on their necessity for portability and their oil system’s capacity I recommended that they rent our 5-GPM SFC spin-on filter cart, with which we were to include filter elements that both absorb water and also filter out particulate down to 1 micron in size.

Within a few days after delivering our SFC to Brian’s team, they utilized the filter cart to filter all the oil in the reservoir. Afterwards they also installed desiccant breathers as I recommended to them during my site visit. The final oil analysis lab test results showed that oil had been significantly reduced in moisture content and that the achieved their target ISO cleanliness level for the particulate, more so than they originally anticipated. Brian and his company are now happy with our service. We really find pleasure in providing successful results such as these!

Filter Vessel Delivers Success for De-Silting Operation on River Barge

December 19, 2013

River Barge Desilting Bag Filter VesselDave contacted me on a Wednesday morning. He was the purchasing manager at a marine services/underwater engineering company. They were awarded the contract for a de-silting operation in a large river in the northeast. They needed to pump silt in to a barge, and then from that barge to a hopper barge, filter the sediment, and then back into the ocean. The water was to sit in the hopper barge over night and then be skimmed to another barge, and finally needed to be filtered of all particulate larger than 200 micron before being pumped back into the ocean at a rate of 1000 GPM. As such, Dave expressed his interest in renting a filtration vessel that could be utilized on the boat.

I reviewed our list of rental vessels to see if we had a bag filter housing which would handle 1000 GPM. Luckily I found a horizontal bag filter housing which utilized 7-round 80″ long bag filters. I then checked our supplier’s inventory and, once again, luckily we had 60 of them ready to ship. I conveyed all this information to Dave and he quickly placed the order. After we had already begun the process of getting the filter vessel and bag filters shipped to Dave’s location, he contacted me last minute and said that he needed to change the filtration efficiency to 100 micron retention instead of 200 micron. I immediately contacted our supplier and requested a change, to which they responded accordingly after finding some old inventory of 100 micron bags that would fit the same filter vessel. In the end, because of the lower-micron filters and the last minute change, Dave had to pay a little bit extra and wait some more to receive the products, but our inside sales team made sure that they entire process ran correctly and smoothly, and Dave’s company successfully received the filter bag housing that they were expecting, with the 100-micron bag filters that they needed.

River Barge Desilting Bag Filter Vessel (Close-Up)Upon starting up the vessel, Dave discovered that they were going to need more bag filters than they originally anticipated, so he contacted me once again to quickly place an order for more. I made sure to work with our shipping department to expedite the order and the partial shipments in order to keep their de-silting project in operation. I wanted to help them avoid a shut-down and thus have them risk not completing the job in the time-frame that they specified to their customer, which would’ve been bad news. In the end, Dave’s barge filtration operation required the entire time that was allotted to them, but it was completed on time. Success once again!
