Notes:

(1) The displacements 46-64 use the same external casing.
(2) The values shown are valid for an absolute pressure (pass) of 1 bar (14.5 psi]) at the suction inlet port an when operated on mineral oil.
(3) Approximate values.

The C3 46-50-64 series includes variable displacement axial piston pumps designed for use in closed-loop circuits.

Displacement variation occurs through the rotation of a swash plate; by moving beyond the neutral point, flow reversal is achieved.

The unit offers the following range of controls:

  • Manual without neutral reset
  • Manual lever with feedback
  • Proportional hydraulic without feedback
  • Proportional hydraulic with feedback
  • Electric impulse control
  • Electric 2-position (ON-OFF)
  • Automotive
  • Automotive with mechanical adjustment
  • Proportional electric with feedback
  • Proportional electric without feedback

Two mounting provisions for auxiliary pumps and additional options are available:

  • Power limiter
  • Pressure filter
  • Filter with electric clogging sensor
  • Electric cut-off valve
  • Shuttle valve
  • Hydraulic inching
  • Mechanical inching
  • Provision - SAE “A” Z9 - 16/32-DP
  • Provision - SAE “A-A” Z11 - 16/32-DP
  • Provision - SAE “B” Z13 - 16/32-DP
  • Provision - SAE “B-B” Z15 - 16/32-DP

Peak conditions must not exceed 1% of each minute.

Avoid simultaneous operation at maximum speed and maximum pressure.
