CASE STUDY: CONCRETE PUMPING AND CASTROL® PYROPLEX® BLUE 2 GREASE

PRODUCT NEWS / Post date: 2 August 2017

Customer Situation

  • Fleet of eleven concrete-pumping trucks with Z booms used for low-clearance job sites and hard-to-reach areas
  • Auger bearing main shaft has brass bushings that wear out on a normal basis; the auger bearings in the hopper have to keep the blades turning during a concrete pour
  • The applied grease has to not only lubricate these bearings, but also minimize concrete and water from getting into the bearings
  • Each truck is equipped with an auto greaser


Before Change in Grease

  • Auger bearings changed every 6-12 months
  • Grease usage was 3 to 4 400-pound drums per year


Castrol Solution

  • Converted customer to Castrol Pyroplex Blue 2 grease for its hydro-activated and pumpability properties along with better adhesion in the subject applications


After Change in Grease

  • Auger bearings are lasting 2 to 2.5 years
  • Grease usage has been cut to 1.5 400-pound drums per year


Maintenance Recommendations

  • Purge all bearings, grease fittings, and auto lube systems with Castrol Pyroplex Blue 2
  • Reapply often until all grease is purged out
  • Begin to lengthen periods between greasing


Customer Results

  • Customer is using 50% less grease and is experiencing twice the bearing life in the augers
  • With savings on downtime, parts, labor, and grease, this customer has experienced an annual savings of $44,000 for the entire fleet
