HIGH BACK PRESSURE BREAKERS

Now you can use your skid steer, backhoe, excavator, or tractor to power your breaker.  These tools are designed to work with high back pressure and represent a breakthrough in versatility.

These units are able to work on a maximum return/back pressure of 508psi (200 psi for non-high back pressure units)

  • Flow requirement of 8 gpm (Same as non-high back pressure units).
  • Working pressure at approximately 1668 to 1885psi with maximum relief valve setting at 2200 psi. (Same as non-high back pressure units.)
  • To ensure the tool is receiving the correct flow of 8gpm, you will need OFD8 (1801164319).  Max flow in:  32 gpm; Max pressure:  360psi
  • No warranty for tools damaged by over-pressure when run without an oil flow divider.
  • **For John Deere and Bobcat Skidsteer that deliver between 16 and 30gpm - pressure reduction hoses must be used in conjuntion with the OFD
