Pumping unit also called pump jacks is a kind of equipment for oil extraction, which used in oilfield. The pumping unit is the most important lifting equipment in the rod pumping system.
According to whether there is a beam, it can be divided into beam pumping unit and beamless pumping unit.
Beam pumping unit is devided into C series and B series groups. C series pump jacks are crank balance beam pumping unit, B series pump jacks are beam balance pumping unit.
Both types are manufactured in accordance with API 11E standard.
The main parts of pumping unit include the beam, horse head, reducer,pitman, samson post, base, equalizer, wireline, crank, counter weights, break assembly, also with fence and ladder,
if required, we also can equip the pumping unit with motor and control pannel. And the motor and control pannel could be explosion proof type.
The main parameters of pumping unit are polished rod capacity, stroke frequency, and stroke length.
