Problem with replacing text in sed containing "|"

Question

I am trying to replace "watermarks" to nothing from my pdf using sed command to increase text size on my e-reader, but when i try to replace it stays becouse it have | character in the middle. The text i want to replace with nothing is:

• "Company | exampl3.com"
• "Page 1" > "Page xxx"

The commands i was trying to use:

pdftk PDF.pdf output PDF_UN.pdf uncompress

sed -i 's/Company | exampl3.com//g' PDF_UN.pdf

When i try to replace some words or/and sentences it works fine and is fast.
