Castrol Alpha VT 32
01736 757002VISCOSITY - ISO 32
Castrol Alpha VT 32 Turbo transmission oil
Castrol Alpha™ VT 32 has been developed specifically for Voith Turbo transmissions to provide long service life and realibility, and to exceed the Voith specification 3.90-8e_2011-07
Castrol Alpha VT 32 is formulated for hydrokinetic transmissions used mainly in railway locomotives. Other applications include trucks and heavy off-highway equipment incorporating this type of transmission unit. The oil is also suitable for conventional industrial gearboxes where a low-viscosity oil is suitable. This oil provides higher load-carrying performance, together with excellent oxidation resistance, anti-corrosion and minimal foaming.
Alpha VT 32 is fully compatible with nitrile, silicone and fluropolymer seal materials.
Castrol Alpha VT 32 meets the requirements of:
Voith Turbo Specification 3.90-8e_2011-07
- Long service life
- Excellent load carrying and micropitting resistance
- Good seal compatibility
- Low foam and rapid air release
- Excellent demulsification
