3DX Pumps

The 3DX series of pumps was a very popular pump placed on many pressure washers. The series consists of:
  • 3DX29GSI: 2500 Max PSI, 2.9 GPM
  • 3DX30GSI: 2500 Max PSI, 3.0 GPM

These pumps are all basically the same and contain the same parts. There are only a few differences (well just one, the crankshaft), you should refer to the parts breakdown for information on your specific pump (see link below).
