Patented three chamber hydraulic cylinder using nitrogen as counterweight and hydraulic fluid to move the fluid

• The pumping unit has a 2:1 stroke length ratio (cylinder only moves at 50% of Polished Rod Stroke length

The HPU powers and is the primary interface for the SSi system. Ranges of Horse Power - 40 to 250

• Patented auto-stroke Logic and Smart Speed Logic II (Patent Pending)
• Increase/decrease speeds and change stroke lengths at a touch of a button while production continues. Up and Down Strokes are independent of each other. Balancing of the well can be done without stopping production.
• Integrated Pump Off Control

Contact vendor for more details

• Intelligent unit speed changes – Independent up/down strokes
• Speed/stroke length changes do not require unit shutdown
• Safety
• Fully Compatible with any SCADA System,
  • Units will not start if “no load” detected
  • Safety feature stops system immediately upon detection of a rod break
• Remote control of system including unit start/stop
• Mounted on 3 H Beams instead of wellhead, more cost effective workovers

Competes with small ESPs and large rod pumps.

• For wells with high production - this hydraulic lift system allows the switch from ESP earlier than rod lift due to higher stroke and max load
• For deviated wells - this hydraulic lift system allows both longer/slower stroke and more ability to tailor the top and bottom of stroke to minimize reliability issues and solve tagging issues
• For gassy wells - the long stroke and flexibility in stroke start/stop position allows for higher compression, limiting gas locking issues and improving
