This hydraulic pump is mainly applied in:

  • Large wheel loaders
  • Wheel dozers
  • Mining support equipment
  • Quarry machinery
  • Heavy construction equipment
  • Material handling machines

Compatible Caterpillar equipment includes:

  • CAT 844 Wheel Dozer
  • CAT 990 Wheel Loader
  • CAT 990 II Wheel Loader

The pump is used in hydraulic systems responsible for:

  • Boom lifting and bucket operation
  • Steering hydraulic circuits
  • Hydraulic implement control
  • Heavy-load material handling operations
  • Continuous-duty construction applications

Designed for severe working environments, the CAT 20R-3301 provides reliable hydraulic power under high loads, vibration, dust, and long operating cycles. It helps maintain machine productivity and reduces downtime in mining and construction applications.
