3. Specifications
Liquids used
A hydraulic mineral oil with viscosity 20 ... 37 cSt at 40 °C and viscosity grade VG20 to
VG37 to ISO 3448 (BS 4231) is used for the model CPP1200-X hydraulic comparison
test pump. Most users will be able to obtain locally suitable oil (see below) as used in
hydraulic machinery. However, for the convenience of users we can supply a 500 ml
bottle of oil, viscosity grade VG22.

Other liquids
The model CPP1200-X hydraulic comparison test pump is designed for use with mineral
oils. If an end user wishes to use it on another fluid, it is the end user responsibility to
ensure that the fluid is compatible with high tensile brass, stainless steel, mild steel, and
nitrile rubber, which are the materials that will come into contact with the fluid.
Fluids, which attack ABS, should be used with caution. Continual
immersion of the cover in such fluids will cause deterioration. Spillages
should be wiped off immediately.
Wear safety goggles!
Protect eyes from flying particles and liquid splashes.
