Medium-Pressure Piston - Fixed

Medium-Pressure-Fixed Eaton's medium-pressure fixed piston motors offer an attractive market solution in a number of mobile and industrial applications with a unique combination of product strengths. Featuring displacements from 10 to 83cc, a pressure rating of 350 bar, a speed rating up to 6,000 rpm, and a through drive option. Eaton's medium-pressure fixed piston motors are a great choice for many applications, including propel, fan drive and agricultural seeding and planting.

Addresses these engineering challenges:

  • Applications that require high speed (>4000 rpm) have to reach for bent axis motors, which can be costly and do not offer any through drive options.

Features and Benefits

  • Numerous shaft and mounting options, three fixed displacement models and two variable displacement models provide flexibility in possible applications
  • Lightweight, durable housing improves overall quality while allowing accessibility for ease of service

Technical Information

  • Displacement Range: 32.9 cc - 49.2 cc {2.01 in - 3.00 in}
  • Speed (max.): 3600 RPM
  • Rated Pressures: to 3000–5000 psi [210–345 bar]; intermittent to 5400 psi [370 bar]
