LUFKIN Hi-Pro Pump
LUFKIN Don-Nan
Addresses mature wells producing more water than initially anticipated, letting operators overcome that restriction without replacing the tubing string with larger tubing — using a plunger whose outer diameter exceeds the tubing's inner diameter.
Key Features/Specs:
- Accommodates higher fluid volumes than insert pumps
- Largest bore rod pump available
- Heavy-walled barrel construction
- Runs across bore sizes 2-1/4" to 3-3/4"
- Runs entirely on the tubing string (unlike API tubing pumps)
- Rod string connects via sinker bar, polished rod, and on-off tool
- Requires tubing removal for service access
