S45 Axial Piston Open Circuit Pump

Series 45 is a complete family of high performance variable displacement, axial piston pumps. Each frame is designed to exceed the demanding work function requirements of the mobile equipment marketplace. Each frame within the Series 45 family is uniquely designed to optimize performance, size, and cost.

High Performance
• Displacements from 25 cm³ - 147 cm³ [1.53 - 8.97 in 3/rev]
• Speeds up to 3600 rpm
• Pressures up to 310 bar [4495 psi]
• Variety of control system options including load sensing and pressure compensated

Latest Technology
• Customer-driven using quality function deployment (QFD) and design for manufacturability (DFM) techniques
• Optimized design maximizes efficiency and quiet operation
• Computer-modeled castings to optimize inlet conditions for maximum pump speed
• Compact package size minimizing installation space requirements
• Heavy-duty tapered roller bearings for long life
• Single piece rigid housing to reduce noise and leak paths
• Integrated controls for high speed response and system stability

  • Integrated gauge ports for monitoring operating conditions
  • Robust input shaft bearings to handle large external shaft loads
  • No gasket joints
  • Significantly fewer parts
  • Long service life
  • Manufactured to rigid quality standards
  • Proven in both laboratory and field
  • Designed to rigorous standards
