Hydraulic Pumping Unit

Known as a leader and innovator in artificial lift solutions, Lufkin continues the tradition with the introduction of the Hydraulic Pumping Unit (HPU) which is supported by the Lufkin Hydraulic Lift group (LHL). This innovative solution employs patented rod string management technology, featuring three limit switches positioned on the tower to monitor the exact position of the rod string. The location data is then processed by Lufkin’s proven controller to precisely deliver hydraulic fluid through the proportioning valve to optimize every stroke and accurately regulate the stroke rate between one half and four strokes-per-minute.

With a minimal footprint, rapid installation and few moving parts, the HPU provides a cost-effective solution for dewatering low volume oil and natural gas wells. We design these units with flexibility in mind and offer natural gas, diesel and electric prime movers to meet your unique requirements. These units deliver a stroke length up to 168 inches and achieve 30,500 lbs peak polish rod load. Power units are available as skids or enclosures for environments where noise and security are a concern.

What is Hydraulic Rod Lift?

The HPU uses a hydraulic piston to vertically lift the fluid from the well.

UP STROKE: Hydraulic Lift

DOWN STROKE: Controlled descent using rod string weight
