Alpha™ SP 150 P

1 of 2 products in this brand
Castrol Alpha™ SP 150 P (previously called Energol™ GR-XP 150 Plus) is based upon highly refined mineral oil, enhanced with extreme pressure additive technology. This provides good thermal stability, high load carrying capacity and resistance to microscopic wear, known as micropitting protection. The high load carrying capacity has been boosted over conventional gear oils of this type for specific applications.

Features & Benefits

Advantages
  • Extreme Pressure (EP) performance gives high protection of gears against wear and shock-loading.
  • Good water separation characteristics means reduced down time through prolonged lubricant life and increased equipment reliability.
  • High protection against corrosion and wear resulting in less maintenance.

Applications & Uses

Application Area
Applications

Alpha SP 150 P is recommended for the lubrication of industrial gear boxes using forced circulation or splash and oil bath lubrication. It may be used for the lubrication of spur and helical gears and in some lightly loaded worm type gear applications.
The increased load carrying capacity, highlighted by the high Brugger value makes Alpha SP 150 P particularly suitable for Müller Weingarten equipment.
