Overview
ISO VG 46 is a hydraulic oil in the ISO VG 46 viscosity grade. Under ISO 3448, ISO VG 46 means a kinematic viscosity of 41.4 to 50.6 cSt at 40 °C; the published value for this product is 46 cSt.
The specification table also lists viscosity at 100 °C (6.5 cSt), viscosity index 95, pour point -9 °C, flash point 210 °C and density, each with its test method.
Application
Pumps and circuits whose manufacturer specifies ISO VG 46 at the system's operating temperature.
Feature
KV40 of 46 cSt is inside the ISO VG 46 band (41.4–50.6 cSt).
Feature
KV100 6.5 cSt, VI 95, pour point -9 °C, flash point 210 °C.
Use the viscosity range in the pump manufacturer's documentation at your operating temperature. Lower grades suit colder conditions or high-speed pumps; higher grades suit higher temperatures and loads.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
