How does it work?

Sucker Rod Pump

Simply, converting rotary motion to reciprocating

vertical motion

Sucker Rod Pump

The Beam Pumping unit (pump jack or surface pumping unit) is used to stroke the bottom hole pump up and down so that it will pump reservoir fluids to surface.

This is accomplished by converting rotary motion to reciprocating vertical motion.

Rotary power is supplied to a gearbox by an electric motor or gas engine.

The gearbox uses a series of gears to convert this high speed power to low speed power. (Usually a ratio of approximately 30 to 1 on a double reduction unit).

The gearbox turns the cranks and the cranks lift the pitman arms up and down (rotary to reciprocating).

Sucker Rod Pump

The pitman arms move the walking beam up and down consequently the horses head has to go up and down.

This action causes the bridle cable to move the carrier bar up and down which in turn moves the sucker rod system up and down, and consequently the traveling valve which connect to plunger.

Insert Pumps

Pump is run inside the tubing attached to sucker

rods.

Pump size is limited by tubing size.

Lower flow rates than tubing pump.
