High-Pressure Filter for Petrochemical Pump Stations – Durable, Precise, Corrosion-Resistant

Product Performance

Excellent High-Pressure Resistance

The filter is specifically designed for high-pressure petrochemical hydraulic pump station 

conditions, operating without leakage or structural damage under rated pressure. 

Its robust construction ensures reliable performance even during pressure surges and 

system fluctuations.

High Filtration Precision

The unit accurately captures fine impurities, effectively controlling hydraulic oil 

contamination levels and maintaining oil cleanliness within specified limits. 

This high precision protects sensitive components such as servo valves, pumps, 

and actuators from particle-induced wear.

Large Dirt-Holding Capacity

The filter element features strong clogging resistance and long service life,

 reducing the frequency of element replacement. This lowers overall operation and

 maintenance costs while minimizing system downtime for maintenance activities.

Low Operating Resistance

Designed with minimal flow restriction, the filter does not adversely affect the oil circulation 

efficiency of the hydraulic pump station. It is suitable for long-term continuous operation 

without causing excessive pressure drop or energy loss.

Technical Specifications

Shell Construction

The housing is manufactured from high-strength anti-corrosion material, 

resistant to petrochemical medium corrosion and suitable for harsh petrochemical working 

conditions. Material selection considers both mechanical strength and chemical 

compatibility with various hydraulic fluids.

High-Pressure Sealing Structure

The filter is equipped with a high-pressure sealing system that provides excellent sealing 

performance, able to withstand oil impact under high-pressure operation without leakage. 

The seal design accounts for thermal expansion, pressure cycling, and chemical exposure.

Filter Element

High-pressure and wear-resistant filter elements are selected to maintain stable filtration 

efficiency over extended service life. The element media is chosen to balance filtration 

precision with dirt-holding capacity, suitable for high-pressure hydraulic oil purification needs.

Monitoring Options

Optional differential pressure alarm devices can be installed to monitor filter element status 

in real time. This allows timely replacement when the element becomes saturated, 

ensuring consistent filtration effectiveness and preventing bypass contamination.

Scope of Application

The high-pressure filter is primarily used for oil purification of hydraulic pump stations in 

the petrochemical industry. It is suitable for high-pressure hydraulic systems in various

 petrochemical facilities including oil refineries and chemical plants. The unit can purify

 hydraulic oil, fire-resistant hydraulic oil, and other industrial fluids.

Beyond the petrochemical sector, the filter is also applicable to high-pressure hydraulic 

systems in metallurgy, electric power, and other heavy industries where reliable filtration 

under high pressure and demanding conditions is required.
