Modern high pressure hydraulic systems are demanding. Better controls and long component life are expected. To deliver the high standards of performance, hydraulic components are built with tighter tolerances increasing their sensitivity to contamination.

That's where Parker Pressure Filters come into play. Pressure filters are used to protect downstream components from contamination, protecting these critical components from catastrophic failure. They filter out ingressed contamination before it jams a valve or scores a cylinder. They block pump-generated debris before it gets to servo or proportional valves.

The design objective for all Parker filters is to achieve a sensible balance between cost and performance. Using state of the art technology to arrive at innovative yet practical designs, offers a cost effective option for both OEM's and users alike. Parker Pressure Filters are a key ingredient in meeting today's system demands.

The Parker 50P High Pressure Filter Series allows for each filter to be customized, closely matching any specific system needs. Choose the options which best fit your application. No need to waste money on features you don't need!

Design
The Parker 50P Series High Pressure Filters are base mounted, which provides several possible advantages. The bowl up mounting makes servicing the elements quick and easy. Simply remove the top cover to access the element. A drain port is provided to allow the oil to be removed from filter prior to element servicing. This design reduces the possibility of oil spillage and injury to maintenance personnel.

The Parker 50P Series has optional manifold porting for space saving design that reduces the number of fittings and potential leak points. The porting is also designed to match the installation of many other manufacturers.

Available in single, double, and triple lengths, and utilizes Microglass III media in 2, 5, 10 and 20 microns for the industry's best particle removal efficiency and retention. Most significant to note, the Parker 50P Series meets the SAE HF4 automotive standard, ensuring the safety, quality and effectiveness of products.


50PR Reverse Flow Filter
Also Available: The Parker 50PR - designed specifically for hydrostatic transmission loops because of its capability to handle reverse flow.

Closed circuit HSTs frequently reverse direction causing flow to reverse in the fluid lines. Pressure filters installed between pump and motor must be able to handle reverse flow without having contaminant washed off of the elements and back into the system. To prevent such an occurrence, the filters require the use of internal check valves to direct the flow through the element in one direction and around the element in the other. Parker's internal check valve design minimizes additional pressure loss and eliminates the cost associated with external valves and fittings. Also the internal design keeps the envelope dimensions of the filter to a minimum as can be seen on the installation drawing.
