Morris Hydraulic Oil - Liquimatic No 4 ISO 32

ISO VG 32 refers to the viscosity grade according to the International Organization for Standardization. It indicates that the oil has a kinematic viscosity of approximately 32 centistokes (cSt) at 40°C. This is a mid-range viscosity suitable for many hydraulic applications.

No, it is specifically designed for systems requiring an ISO VG 32 viscosity grade and compatible additive package. Always check your equipment manufacturer's specifications to ensure this oil meets their requirements.

An ashless formulation means the oil does not contain metallic additives that can form ash when burned or subjected to high temperatures. This helps prevent deposit formation in critical areas like valve spools and reduces filter plugging, leading to a cleaner system and longer oil life.

It is generally not recommended to mix different hydraulic oils, even if they have the same viscosity grade, as additive packages can be incompatible and may lead to reduced performance or system damage. It's best to use only Liquimatic No 4 ISO 32 or to thoroughly flush the system before changing fluid types.

The oil change interval depends heavily on the operating conditions, system design, and manufacturer recommendations. Regular oil analysis can help determine the optimal change interval for your specific application. As a general guideline, follow the equipment manufacturer's service manual.

It means the oil contains additives that actively prevent the formation of rust on ferrous metal parts and slow down the degradation of the oil itself due to oxidation. This leads to improved component longevity and sustained fluid performance, especially in the presence of moisture or air.

Yes, the rapid air release properties of this oil make it well-suited for hydrostatic drives, helping to ensure smooth and responsive operation by quickly expelling entrained air.

This could indicate excessive air in the system. Ensure the rapid air release function is working correctly and check for any potential air ingress points. Low oil level can also cause this; check and top up if necessary.

Verify that the system's operating conditions (pressure, temperature) do not exceed the designed limits for an ISO VG 32 oil. Ensure no contamination has occurred and that the oil has not degraded. If the issue persists, consider if a higher viscosity grade might be needed for extreme loads.

While this oil meets modern filterability requirements, excessive or rapid clogging may indicate system contamination or the breakdown of internal components. Inspect the system for wear particles and clean thoroughly. Ensure the filter element is appropriate for the system.

Although the oil is rust and oxidation inhibited, severe contamination with water or corrosive agents can overwhelm its protective capabilities. Drain and flush the system, then refill with fresh oil. Investigate the source of contamination.
