Pumping Unit
CRANK BALANCE PUMPING UNIT
API C series pumping unit adopts crank balance is the most widely used artificial lift equipment in oil recovering produc tions, which conform to API Spec 11 E and relevant domestic petroleum industry standard GB/T29021-2012.
ENHANCEDGEOMETRY PUMPING UNIT
The API Enhanced Geometry (torque max) pumping unit has similar structure to the crank balancing PU which adopts phased crank holes. It is a special design with energy-saving features and popular and widely used in the oil fields, which conforms to API Spec 11 E and relevant domestic petroleum industry standard GB/T29021-2012
Long Stroke BPU’s
Long stroke pumping unit has the features of long stroke length, low stroke frequency, big load capacity. The special de-signed mechanical rotation chain makes it unique in aspects of large pump lifting, heavy oil recovery, and small pump deep-pumping, with a max load of 22.7T (50000LB) and max stroke length 9.3m (366in). The belt-type long stroke pumping unit is becoming more and more popular and widely used with its high efficiency, energy saving, environmentally friendly and durable advantages.
