Tubing Pumps vs. Insert Pump
z Barrel Assembly of this type pump is screwed onto,
and becomes part of the tubing.
z Larger bore than a rod pump, thus it produces a
greater volume of fluid in any give diameter of tubing
z The complete pump is attached to, and inserted into
the well tubing with the sucker rod string.
z As a complete unit, this pump may be pulled out of
the well without pulling the tubing.

Rod Pump
Operation - Concept
Visualization of Rod Pump Working
(A) (B) (C)
Pump grabs a “bite” of fluid
on each downstroke of the
pump, as the “mouth” of the
traveling valve opens on the
downstroke, and grabs a
bite of whatever is within the
compression chamber.

Rod Pump
Operation - Concept
Upstroke closes the
traveling valve, traps the
fluids in the chamber and
physically lifts them up the
well a few feet. This bite is
simply stacked below the
previous bite until enough
bites start running out at
the surface of the well.
