Synolex Venus S1 HLP 32
Premium
Hydraulic Fluid

Synolex Venus S1 HLP 32 is a high-quality mineral anti-wear hydraulic fluid for systems requiring an HLP / HM oil in ISO VG 32. It provides effective lubrication and smooth power transmission while helping protect pumps, control valves, cylinders, actuators and other critical hydraulic components during continuous service.

Good oxidation and thermal stability help limit sludge and deposit formation and support circuit cleanliness. Anti-wear, rust and corrosion protection, together with good water separation, filterability, air release and foam control, help protect equipment and maintain efficient, stable hydraulic operation. Final viscosity selection should follow the equipment manufacturer’s recommendation and consider operating temperature and ambient conditions.

Key Features and Benefits

• Long Fluid Life and Reduced Maintenance Needs: Resistance to thermal and oxidative degradation helps limit sludge, deposits and oxidation by-products, supporting system cleanliness and dependable fluid performance throughout the service period.
• Effective Anti-Wear Protection: A stable lubricating film and anti-wear additive system help protect pumps and loaded components against surface wear.
• System Cleanliness: Control of deposits and oil-degradation products supports reliable operation of valves, oil passages and filtration equipment.
• Moisture Stability and Corrosion Protection: Rust and corrosion protection helps safeguard metal surfaces in humid environments and where incidental water contamination may occur.
• Good Water Separation: Effective demulsibility promotes separation of free water from the oil, allowing easier removal of water contamination from the reservoir.
• Good Filterability: Supports effective filtration and hydraulic circuit cleanliness while helping reduce the risk of premature filter restriction caused by contamination and deposits.
• Air Release and Foam Control: Helps maintain efficient power transfer, stable pump operation and reduced adverse effects from entrained air, foam and cavitation.
• Maintained Hydraulic Efficiency: The combined effects of fluid stability, wear protection, contamination control and air management support consistent hydraulic response and efficient system operation.
• Smooth Equipment Operation: Suitable frictional characteristics can help reduce stick-slip behavior in sensitive hydraulic components and mechanisms.
• Equipment Compatibility: Suitable for use with most common hydraulic pump designs, subject to equipment-manufacturer recommendations.
• Fluid Compatibility & Miscibility: Compatible with most other mineral oil-based hydraulic fluids; however, it should not be mixed with fire-resistant or environmentally acceptable hydraulic fluids.
• Seal & Paint Compatibility: Compatible with seal materials and coatings normally specified for use with mineral oils.

Handling & Storage Advice

Store the product in its original, properly sealed and clearly identified container in a dry, sheltered and well-ventilated location. Protect it from excessive heat, direct sunlight, water and contamination. Use clean pumps, hoses and containers during transfer and filling to prevent the ingress of dust, moisture or other lubricants. Refer to the product Safety Data Sheet for safe-handling requirements. Used oil should be delivered to an authorized collection or recycling facility in accordance with applicable local requirements.

Directions for Use

Before use, verify the viscosity grade, performance level and equipment-manufacturer requirements. During an oil change, inspect the reservoir, hydraulic circuit and filters for contamination, water and deposits, and clean or service them where necessary. Fill the system using clean transfer equipment and suitable filtration where practical. Check compatibility before mixing with another mineral hydraulic oil, and do not mix with fire-resistant, biodegradable or other hydraulic fluids based on different chemistries. Monitor oil level, operating temperature, filter condition and water contamination, and establish change intervals according to manufacturer guidance and, where available, oil-condition monitoring.
