Hydraulic Solutions
Wear, Friction & Seal Support
Common Hydraulic Challenges
Industrial hydraulic systems operate under high load, heat, pressure variation, and continuous mechanical stress. Over time, these conditions can affect lubrication performance, increase wear, and lead to operational instability or unplanned maintenance.
Friction & Wear
Continuous load and movement increases friction and wear on gears, pumps, bearings, valves, and seals.
Heat & Oil Stress
High operating temperatures and demanding cycles can reduce lubricant stability and performance.
Leakage & Pressure Loss
Worn seals or pressure fluctuations can lead to leakage, reduced efficiency, and unstable operation.
Unplanned Maintenance
Wear, leakage, heat, and lubrication issues can create pressure for early intervention or downtime.

Typical Hydraulic Applications & System Types
HY Guard and HY Seal products can be considered for selected mineral oil-based hydraulic systems where friction, wear, leakage, pressure variation, or unstable operation are key concerns.
Typical applications include:
Hydraulic cylinders
Pumps and valves
Bearings and sliding surfaces
Hydraulic power units
Industrial and marine hydraulic systems
Built Around Hydralic Operating Conditions
Hydraulic systems operate under demanding pressure and load conditions that may affect sealing stability, fluid performance, and long-term system reliability.
Key operating factors include:
- Continuous pressure variation
- Frequent load changes and system cycling
- Valve activity and flow fluctuations
- Seal exposure under high-pressure conditions
- Fluid stress, temperature variation, and contamination risk
Why it
matters:
Over time, these conditions may contribute to oil leakage, seal wear, reduced
fluid stability, pressure irregularities, and increased uncertainty around
hydraulic system reliability.
A Progressive Hydralic Solution Structure
The HY range is structured from preventive protection to stronger hydraulic support for demanding system conditions.
The range is built around four application levels:
HY Guard — preventive protection for stable hydraulic systems
HY Core — standard support for smaller leakage cases or early performance deviations
HY Plus — reinforced support for moderate leakage, pressure variation, or demanding conditions
HY Max — maximum support for severe leakage cases or critical hydraulic conditions
Why it matters:
This structure helps operators identify a relevant starting point based on
hydraulic system condition, leakage behaviour, pressure stability, and
operating demands.
Hydraulic Product Selection Factors
The right product depends on the actual hydraulic system and operating situation.
Typical selection factors include:
- Leakage behaviour and development over time
- Hydraulic oil volume
- Fluid type currently in use
- Seal condition and wear pattern
- Pressure variation and operating load
- Filtration setup and contamination level
- Service objective before next maintenance window or dry dock
Why it
matters:
These factors help determine whether the focus should be preventive protection,
standard leakage support, or stronger hydraulic support for demanding system
conditions.
Technical Review Before Hydralic Application
Before application, the hydraulic system should be reviewed to ensure the correct product selection and quantity.
Typical review points include:
- Hydraulic oil volume
- Current leakage level
- Fluid type and viscosity
- Seal condition and service history
- Pressure profile and load variation
- Filtration setup and system cleanliness
Why it
matters:
A technical review helps reduce application risk and ensures the selected HY
product is matched to the actual hydraulic system condition and operating
environment.
