Parker Hydraulic Filters: Maximum Protection for Industrial Hydraulic Systems

What Is a Hydraulic Filter?

A hydraulic filter is a critical component in a hydraulic system that functions to remove contaminants such as dust, metal particles, scale, water, and other microscopic debris from hydraulic oil before the fluid circulates through various system components.

Many studies show that more than 70% of hydraulic system failures are caused by fluid contamination. Even particles smaller than what the human eye can see can cause wear on pumps, valves, hydraulic motors, cylinders, and other precision components.

Therefore, using a hydraulic filter is not merely an optional accessory, but an essential investment to maintain the reliability, efficiency, and lifespan of the entire hydraulic system.

How Does a Hydraulic Filter Work?

In simple terms, a hydraulic filter works by filtering fluid as oil flows through the filter media.

Here is how it works:

Parker Hydraulic Filter Product Range

Suction Line Filter

Suction filters are installed before the hydraulic pump to prevent large particles from entering the pump.

Function

Protects the pump from coarse contaminants
Extends pump lifespan
Reduces the risk of cavitation caused by foreign objects

Parker Series

G Series
ModuFlow Suction Filters
Tank Top Suction Filter

Suitable For

Mobile Hydraulics
Agricultural Equipment
Construction Machinery
Mining Equipment

Pressure Line Filter

Pressure line filters are installed after the pump and before the oil reaches valves or actuators.

This type provides the highest level of protection because it operates under high pressure.

Function

Protects servo valves
Protects proportional valves
Protects actuators
Maintains fluid cleanliness in high-pressure systems
