Changing hydraulic pump cartridge can give me more torque?

Click For Summary
SUMMARY

Changing the hydraulic pump cartridge from 21 GPM to 12 GPM will indeed increase torque at the winch HD motor while maintaining the same pressure and engine horsepower. This is due to the relationship between flow rate and torque in hydraulic systems. A formula to calculate the percentage increase in torque based on the change in flow rate is necessary for precise measurements. Reference materials, such as the hydraulic motor calculations from Nott Company, provide valuable insights into these calculations.

PREREQUISITES
  • Understanding of hydraulic systems and torque principles
  • Knowledge of flow rate (GPM) and its impact on hydraulic performance
  • Familiarity with hydraulic motor specifications and calculations
  • Basic grasp of horsepower and engine RPM relationships
NEXT STEPS
  • Research the formula for calculating torque increase based on flow rate changes
  • Explore hydraulic motor performance metrics and specifications
  • Learn about the impact of pressure and horsepower on hydraulic systems
  • Review resources on hydraulic system optimization techniques
USEFUL FOR

Hydraulic engineers, mechanical engineers, and technicians involved in hydraulic system design and optimization will benefit from this discussion.

hi all,
changing my cartridge of 21 gpm to a small one 12 gpm I will have more torque whith less rotation in my winch hd motor? it's sound correct?
if yes have a formula to know how much more % ?
obs - keeping same pressure and same engine HP drive rpm .
in case of will need more horsepower in hydraulic pump drive no problem , the engine have plenty.
