When a hydraulic component fails or when the hydraulic system is opened, there’s a high risk of contamination being introduced which can be detrimental to the performance of the machine and its service life. It’s essential to filter the fluid to re-establish its proper cleanliness and keep your Geoprobe® machine in peak operating condition.

“The inline filter actually allows your machine to become its own filtration system,” explained Darren Stanley, Geoprobe® Resource Service Center Manager. It can be used in conjunction with your machine’s regular hydraulic service or after a hydraulic component failure. The new filter assembly eliminates the need for your Geoprobe® machine to spend time in the hydraulic shop to filter the hydraulic fluid. “We use a 3 micron filter in this system which more than adequately filters your hydraulic fluid,” Darren said. Not all shops use a filter size that’s adequate for this process. “It’s a good thing for you to know the filter size your hydraulic shop uses to make sure the fluids are adequately filtered,” he added. Transportation to and from the shop, and shop labor costs are eliminated. The inline filter system can be used in the field which keeps the machine making money.

The High-Pressure Inline Filter Assembly (37374) includes fittings which allows the assembly to adapt to most Geoprobe® machines. Hydraulic fluid is the lifeblood of a Geoprobe® machine, and keeping the hydraulic fluid clean is extremely important. The pumps, valves, cylinders, motors, and hammer would sit silent without this critical fluid. And as a Geoprobe® machine’s components become more sophisticated with tighter tolerances and systems pressures increasing, fluid cleanliness becomes even more vital to maintain dependable performance and to extend service life.

Some industry studies suggest proper filtration can increase hydraulic component life by as much as four times. That’s why Geoprobe® engineers and the service team use only the highest quality filters and fluids in Geoprobe® machines. And with the introduction of the new inline filtering system, it’s easier and less expensive to keep your machine’s hydraulics in peak operating condition.
