Did You Forget the Suction Strainer?

Everyone knows the value in protecting something that’s important. Any aspiring championship football team makes sure its star quarterback gets offensive linemen that allow him to perform at the highest level. This similarly goes for the pump of a critical hydraulic system.

In the American Filtration & Separations Society’s (AFS) latest “One-Minute Filtration Article,” published at the trade group’s website, writer Don Krause, general manager of Flow Ezy Filters Inc., advocates the use of pump suction strainers to separate harmful particulates from a hydraulic or fluid power system. Krause writes the pump is the “‘heart’ of a hydraulic system,” and without proper filtration, an unprotected system could stop dead in its tracks.

Continuing the article, Krause notes the importance of balancing filtration and suction-line flow requirements. Excessive restriction of flow will cause a pump to cavitate, damaging it, and therefore suction strainers “are commonly available with a built-in bypass valve,” he writes. And he adds that the proper level of filtration for any system is determined by the type of pump being used, the fluid’s viscosity and flow rate, and the system’s pressure.

Krause writes:

Take a proactive approach to insure your hydraulic system’s proper operation and longevity… Suction strainers are an inexpensive yet effective investment that will safeguard the “heart” of your hydraulic system and, in so doing, prolong its life.

AFS will hold its annual conference May 6-9, 2013, in the Minneapolis-St. Paul area. Themed “Filtration and Separation in the Global Market Recent Advancements – Innovative Solutions,” the event will have sessions on various two-phase separation, fundamental and computational understanding for filtration and separations technology, new and improved areas of testing and new product areas for the global market.

The event’s details can be found here.
