Drillers seeking rotary drilling options - outfitted for air drilling or mud drilling - for larger, deeper wells in tough geologies choose the DRILLMAX® DM650 by Geoprobe® providing power for drilling water wells with 28.5-foot stroke, 40,000 lb pullback, and 8,000 ft-lb torque. 

“I appreciate the design of the new mud pump and the amount of power it has. It’s a very nice, heavy-duty machine," Mark Kelly of Emerald Coast in Alabama said.

Possessing power to reach depth with ability to support weight of steel casing while drilling water wells, the DRILLMAX® DM650 by Geoprobe® is engineered to handle 24-inch wells. Top head and drill mast features contribute to its ability to quietly and smoothly drill deeper, bigger holes. 

“It looks well engineered with everything in the right spot. It’s probably bigger than I need, but if I bought a new rig, it would be what I want,” Mario D'Agostino of D'Agostino Well & Water Services said.

Drawn to the Geoprobe®DM650 for its attention to detail with a simple control center and clean routing of hydraulic hoses, other features catching drillers' eyes include:

  • ample power, both on and off the road
  • increased speed and efficiency running multiple functions without losing hydraulic power 
  • speed and labor savings of the rod carousel

DM250 Rigs for Water Well Drilling 

When it comes to power for drilling water wells, looks can be deceiving.

“Our industry has a hang up on bigger is better,” said Ricky Cosnahan, owner, DJ Pump Service, Georgia. “If a 24-inch wrench will break pipe loose, then you get the 36-inch to make sure you have the power. Just because it’s little doesn’t mean it doesn’t have power.”

Driller Chris Adkison attributes their success to the top head speed of the DM250 for cleaner, straighter well development in significantly less time - cutting the hole in hours instead of days.

“Where we drill wells there’s a lot of limestone and blue marl. It would take four days to drill 260 feet and then make a well on the fifth day,” Adkison said. “Now we’re doing it in a day and a half. The blue marl is a dense clay that swells and the DM250 cuts it really well.”

In choosing the small but mighty DM250 with its efficient water well drilling production, read how companies across the nation have added other big business advantages:

  • site accessibility
  • competitive advantage
  • no class A/B CDL required
  • easy mobilization
  • increased production and profit
  • more family time

DM450 Water Drill

Versatility combined with creature comforts like deck-mounted Mudslayer® make the DM450 the driller's choice on a wide-range of water well drilling jobs.

"It's fast and efficient. We get paid by the foot, so we need to make a hole fast as you can, and the DRILLMAX® DM450 [by Geoprobe®] does that," Mark Rhoads, Rhoads Farms, Texas, said.

The DM450 water well drilling rigs complete larger wells while amplifying production rates, ultimately combining for more family time.

"I'm able to complete jobs faster and do more work per week, which means more money and keeping customers happy. It also means more time with my kids and not working weekends trying to prepare for the next week," Mark said.

Drawn to the DM450 for its simplicity, read how customers discovered numerous other benefits:

  • superior safety
  • increased production and profit
  • engineered improvements
  • performance confidence
  • customer service

“The DM250 doesn’t use much fuel and per foot it’s cheaper to operate. Upfront cost is less, and maintenance is less because parts are cheaper and it’s easier to work on. Maintenance wise, it’s really simple. Essentially it’s maintenance free. I can use hand tools to fix what I have to fix. If a hydraulic hose breaks, you can use common stuff you find at an auto parts store.”
