Helping a Heavy Industrial Construction Company to Filter Hydraulic Oil

October 22nd, 2013

Custom Spin-On Filter Cart with ReservoirChris called me in the middle of the week. He was the project manager of a heavy industrial construction company in the Pacific Northwest. His company works on large-scale projects for commercial business enterprises and government agencies, much of their work in the Snake and Columbia River Dam. They also deal with the industrial plant maintenance industry in applications such as Converting Waste to Energy, Aluminum Production, as well as Plywood Mill and Lumber.

As a contractor on a job site, Chris was expected to supply what he called a “hydraulic system charging unit”, adding fluid to the Hydraulic Power Unit (HPU). His particular fluid application (service) was hydraulic oil, more specifically what he liked to all “fish friendly” Mobil 32H. Luckily he provided me with a spec sheet which laid out all of the details that the hydraulic oil filtration system needed to incorporate. Even more luckily, most of the requirements our SFC Spin-On Filter Cart already exhibited, such as the following:

  • The filtration unit needed to be portable.
  • It needed to have an electric motor with an on-off switch.
  • It needed to have a power cord at least 30-feet long (SFC has a 40′ power cord).
  • It needed to be compatible with 110-volt, single phase electricity input power.
  • Its flow rate needed to be 1 GPM (SFC comes in 1-, 5-, 11-, or 22-GPM standard pumps).
  • It needed to be compact enough to maneuver through 30-inch doorways.
  • It need to use spin-on type filters with a by-pass and a level indicator
  • It needed to have seamless stainless tubing

Custom Spin-On Filter Cart with ReservoirUpon reading the requirements I thought it appeared as if they had copied verbatim from the PDF brochure of our SFC Spin-On Filter Cart!

Chris also needed a Hydraulic Fluid Reservoir, which was something new for me, and for which I had never provided a price quote in the past. The reservoir needed to hold 5-gallons, nominal capacity, and also be made of steel. I determined the size that the reservoir needed to be and then decided to use a stainless steel that would be clean and have a bright metal finish like Chris wanted. Then I had to take some measurements and figure out where to mount the reservoir on the frame of the SFC filtration cart.

Next I had to determine where we would mount it on our unit and I was able to take dimensions and determine how we would attach it into the frame of our custom portable filtration cart. Chris also specified that he needed something to remove dirt and moisture from the incoming air so I ended up incorporating a desiccant air breather. The particular breather that I included also provides a visual indication of the desiccant as well as the condition of its filter. We also made sure to use a clear fluid level indicator for the reservoir that was flexible enough to bend and follow the contour of the tank without breaking.

This was definitely a success story since, in addition to already being one of the best filter carts on the market, the fact that we were able to add custom modifications for Chris’s needs really helps make us stand out from other companies which don’t have these type of manufacturing capabilities. I felt proud when I received the following positive feedback from Chris – “Received it today. Looks sharp! Everything looks in good condition.”
