Overview
ISO VG 32 is a hydraulic oil in the ISO VG 32 viscosity grade. Under ISO 3448, ISO VG 32 means a kinematic viscosity of 28.8 to 35.2 cSt at 40 °C; the published value for this product is 32 cSt.
The specification table also lists viscosity at 100 °C (5 cSt), viscosity index 100, pour point -9 °C, flash point 198 °C and density, each with its test method.
Application
Pumps and circuits whose manufacturer specifies ISO VG 32 at the system's operating temperature.
Feature
KV40 of 32 cSt is inside the ISO VG 32 band (28.8–35.2 cSt).
Feature
KV100 5 cSt, VI 100, pour point -9 °C, flash point 198 °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.
