EcoRenovator - View Single Post - DIY well drilling / trench digging for GSHP

I started with low speed high torque hydraulic motor. I used Sauer Danfoss DH 315.

I lowered speed to get even more torque but I did not need it. I had only 1100 Psi of pressure in the system and that was enough.
Here some specs:

Second main component (even first) was water swivel. King swivel 2J
Here some info:

Hydraulic pump I just found one in my garage. It is model 310L. This is all I have about it. It is a bit too small. Hydraulic motor needed more GPM for full speed. But pressure/torque wise pump was big enough.

At the beginning I wanted to use electric motors because I didn't want to disturb neighbors. I used 5 HP electric motor to drive pump and 2HP to run water pump. Water pump need only gas engine because it allows to change its speed and water flow. Hydraulic pump can be driven by electric motor but 5 HP was just enough.

After I switched to gas engine for hydraulics. I used 15 HP Honda-like engine. This was real power.

So next time I will post my experience about using it.
