Abstract: Disclosed is a plunger for use in a sucker-rod pumping system. The plunger reciprocates within a barrel. The plunger comprises first, second, and third sections, in which the first and third sections are sealed against the barrel and in which a second section is between the first and third sections and in some embodiments may be a pull tube. A through passage for production fluid is provided, along with a pressure balancing chamber that is connected to the through passage via a sand snare, where the pressure balancing chamber is operable to equalize pressure on longitudinal sides of the seals, whereas the sand snare operates to restrain solids from reaching the pressure balancing chamber from the through passage (which is carrying the production fluid) and thereby create a slippage flow in the pressure balancing chamber, which equalizes pressure between the balancing chamber and the plunger's through passage.

In one implementation, the downhole pump comprises a barrel having a first valve for controlling fluid flow into the barrel. The first valve includes an interior cavity with a first surface. The downhole pump further includes a plunger housed within the interior cavity of the barrel. The plunger comprises a wiper-plunger having a first circumference to which one or more resilient seals are coupled. The one or more resilient seals seal a first boundary between the first circumference of the wiper- plunger and a first portion of the first surface associated with the barrel. The plunger further comprises a sand separation unit coupled to the wiper-plunger at a first side. The sand separation unit forms a balancing chamber that minimizes a pressure differential across the one or more resilient seals.
