Power Unit found on Maxon's 72-25/30LM model and a few RCM models. This is a complete pump and motor assembly usually for gravity down gates. If your gate is 72-25/30LM and is a power down model you may need part number 253473 instead. If your gate is a RCM series and is a power down model, you may need 250100-24.
Numbers that may appear
We've seen the following numbers on this power unit. These are not Maxon numbers, but rather numbers from the manufacturer. These start with a "S203T-".
- S203T-3648
- S203T-3809
- S203T-4586
They may also have a *
- S203T*3648
- S203T*3809
- S203T*3809
- S203T*4586
Or they may have no seperator
- S203T3648
- S203T3809
- S203T3809
- S203T4586
What's Included?
The following items are included in this full power unit. That said, you can purchase them separately if needed. For our non-technical folks, the full power unit is the best option since it's basically a "plug and play" piece - remove the old one, insert the new one, connect, and you should be good to go.
