Garlock Case Study: Poultry Processing: KLOZURE® ISO-GARD®

Poultry Processing: KLOZURE® ISO-GARD®

ISO-GARD bearing isolators offer exceptional bearing protection for pumps, motors, and bearing supported industrial equipment under the harshest conditions.

ISO-GARD products are constructed using a filled PTFE material which provides excellent chemical resistance.


Food – Poultry Processing


A diversified food processing company, with facilities located
throughout the US.


The customer had persistent problems with sealing the bearings inpicture of iso gard their non-metallic feather picker housings. Using standard lip seals, and with a monthly maintenance program, they still encountered frequent failures. With 72 assemblies (each with two sealing locations) this had a detrimental effect on manufacturing efficiency, and placed a significant burden on the maintenance teams.


Poultry feathers were getting under the lip seals and into the bearing housing, causing frequent and unexpected failures. Daily wash-downs also used a chemical cleaning solution that could also damage the bearings if not sealed correctly. Additionally, there was limited space available for any modification of sealing element.

Meat processing environments are highly regulated by the FDA, so any manufacturing changes must be carefully controlled. Therefore the customer required close support to ensure that any changes could be implemented with full confidence.

Orion Engineered Seals Receives BPD Patent

Orion’s Path to Innovative Bearing Protection Technology and the Issuing of their Patent

Since the opening of Orion Engineered Seals in 2011, their team has been working tirelessly to ensure they have the most innovative products available to increase the reliability of rotating equipment. Among their various product lines, it is their patented Bearing Protection Device (BPD) in its many design variations that separates them from their competition. In March of 2017, after a long yet rewarding process, they were issued a US PATENT for their robust and distinctly innovative Bearing Protection Device (BPD) technology. There is so much they could say about why their products stand above their competition, but today we’re going to focus specifically on the team behind the BPD and why Orion has been so successful.

Orion Engineered Seals - BPDTodd Brickson, Director of Engineering has been working in manufacturing for over 25 years and is enjoying the fruits of his hard work. When designing the BPD device he had a few key points going through his mind.

  • To create the most effective, innovative, and efficient design in bearing protection
  • How can we be innovative in the market and create something that has never been seen before
  • Develop multiple internal layers of contaminant control that would surpass any design available in the market today.

Introducing Orion’s Bearing Protection Device

Orion Engineered Seals - Bearing Protection Device (BPD)The Orion Engineered Seals Bearing Protection Device (BPD)

The Orion Engineered Seals patented Bearing Protection Device (BPD) represents state of the art bearing protection technology which provides maximum protection against contaminants while maintaining lubrication in the bearing.  It is the premier non-contacting bearing protection device on the market today.

The BPD was designed with an understanding of the nature of the bearing housing environment under all operating conditions and utilizes the laws of physics to create what has proven to be the best performing and most cost effective way to protect the bearings of your rotating equipment. Every feature of the BPD is designed to work together as a system.

What Makes Orion’s Bearing Protection Device (BPD) Better

Orion Engineered Seals - Bearing Protection Device (BPD)Two Vertical Internal Chambers – The Orion BPD utilizes the laws of physics with the vertical alignment of the internal chambers to create the most effective and efficient bearing protection device on the market today.

Internal Static Elastomers – BPD is the only true non-contacting device with two internal static elastomers, eliminating the potential of dynamic o-ring hangup.

Contaminant Exclusion – With double exclusion chambers, the Orion BPD can exclude the higher volumes of contaminant, ensuring longer bearing life.

Angled Oil Return – With an angled oil return, the Orion BPD offers enhanced return flow and higher volume capacity with no oil leakage.

Angled Interface – While competing products offer a straight interface, the Orion BPD features an angled interface, giving the contaminant direction and flow to expel more efficiently.
