What is the Eaton HYD HP 171-451?

The Eaton HYD HP 171-451 series generally refers to Eaton’s range of flange-mounted high-pressure filters (often associated with the HP or EHPF product lines depending on the specific generation). These filters are engineered for operating pressures up to 4,568 psi (315 bar) and are crucial for inline mounting in hydraulic systems.

These units are designed to filter mineral oils, H-W emulsions, and synthetic fluids, ensuring that particulate matter does not damage valves, pumps, or actuators downstream. Constructed with high-grade materials like stainless steel (e.g., EN10088-1.4571), they offer superior resistance to corrosion and high intrinsic stability.

Key Features

  • High Pressure Capability: Withstands operating pressures up to 4,568 psi (315 bar) and test pressures up to 6,525 psi.
  • Robust Materials: Stainless steel housing options (316 Ti) provide excellent corrosion resistance, making them suitable for harsh environments.
  • Efficient Filtration: Utilizes star-shaped, pleated filter material which flows from outside to inside, maximizing dirt-retaining capacity and service life.
  • Versatile Application: Compatible with various fluid types including petroleum-based fluids and synthetic lubricants.

Applications and Industries

The Eaton HYD HP 171-451 filters are designed for industries where system failure is not an option. Their high-pressure tolerance and stainless steel construction make them ideal for:

  • Oil & Gas: Protecting hydraulic control systems in offshore and onshore drilling operations where corrosion resistance is vital.
  • Heavy Manufacturing: Used in injection molding machines, die casting, and metal forming presses.
  • Mobility & Construction: Ensuring reliability in the hydraulic circuits of cranes, excavators, and agricultural machinery to prevent jams and component wear.
  • Power Generation: Filtering lubrication systems in turbines and control hydraulics in power plants.

Why Choose Eaton High Pressure Filters?

Eaton is a global leader in filtration, known for engineering solutions that reduce life cycle costs and maximize productivity. The design of the HP 171-451 series focuses on high structural integrity. Pressure peaks—common in hydraulic systems—can be absorbed with a sufficient safety margin, preventing housing fatigue.

Furthermore, the star-pleated filter elements used in these units allow for a compact design with a large filtration surface area. This results in a low pressure drop across the filter and a longer interval between element changes, saving maintenance hours and reducing consumable costs.
