HY Guard

Proactive Hydraulic System Care

HY Guard is a proactive hydraulic treatment designed to help reduce friction, protect loaded contact surfaces, and support stable system performance. Once dispersed in the oil, PTFE particles help form a low-friction protective layer on pumps, valves and cylinders.

System Compatibility & Blending
HY Guard is based on high-quality mineral hydraulic oil and is designed to blend with most commonly used mineral hydraulic lubricants.

Oil Compatibility Note
HY Guard is intended for selected mineral oil-based hydraulic systems. For EAL or bio-oil systems, compatibility must be reviewed separately based on oil type, viscosity, additive package, system condition, and operating environment.

Suitable System Types
HY Guard can be considered for selected mineral oil-based hydraulic systems, including cylinders, pumps, valves, hydraulic power units, and other loaded lubrication systems where friction, wear, heat, or unstable operation are key concerns.

Assessment Before Application
Each application is reviewed individually to ensure the treatment is suitable for the hydraulic system and operating conditions. This helps ensure correct blending, dosage, and application guidance.

Application Example

Developed for real operating conditions across hydraulic systems exposed
to load, pressure variation, heat, and continuous mechanical stress.

Hydraulic Guard – Proactive Care for a Hydraulic Power Unit

System type: Hydraulic power unit with cylinder operation

Hydraulic oil volume: ~500 L
Observed leakage: Within normal operating range

Scenario
The hydraulic system was operating under stable conditions with no significant leakage or pressure loss. During repeated duty cycles, the operator observed elevated oil temperatures and signs of increasing mechanical stress. The goal was to reduce friction, protect loaded contact surfaces, and support stable hydraulic performance as part of routine maintenance.

Action
Based on the system type, oil volume, duty cycle, and operating profile, a proactive treatment was recommended.

Recommended starting point: Hydraulic Guard
Indicative quantity: ~5–7 L total

Application
The product was added during a planned maintenance window, following the recommended dosage and application guidance.

Outcome
The hydraulic system remained stable, with added support for friction control, surface protection, and reliable operation between planned service intervals.
