About the Hy-Pro HPKL27-25MB-PC
Hy-Pro HPKL27-25MB-PC is a filter element rated at 22 µm (25 µm nominal), a beta ratio of β ≥ 4000, 290 psid collapse pressure, and measuring 3.88 in OD, 1.61 in ID, and 28.08 in length. It uses Dualglass media and Nitrile (Buna-N) seals, rated for -45 °F to 225 °F (Donaldson Hy-Pro HP101 Data Sheet FE-101-071724, p.4).
Application & Compatibility
The HY-PRO HPKL27-25MB-PC is designed for use in hydraulic and lubrication filtration systems. With a 25µm nominal (β-rated, absolute 22µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 290 PSID collapse rating indicates the maximum differential pressure this element can withstand during cold starts or bypass conditions without structural failure. Ensure your system's maximum differential pressure does not exceed this rating.
