Did you know that well pumps play a huge role in bringing oil and gas to the surface?<\/p>

These hardworking machines pull valuable resources from deep underground, helping power our cars, homes, and industries. Whether on land or out at sea, well pumps keep energy flowing by moving oil and gas from the ground to the surface where it can begin its journey. Without them, getting liquid oil out of the Earth would be nearly impossible.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Progressive Cavity Pumps (PCPs) are special types of pumps used to move fluids from one place to another. They are great for handling a wide range of fluids, from thin liquids to thick pastes, and can even handle fluids with solids and gases in them.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A Progressing Cavity Pump<\/strong> consists of two helical gears, one nested inside the other, both rotating around parallel, spaced-apart longitudinal axes. The external gear has one more thread or tooth than the internal element. Regardless of the total number of threads, the difference between the two elements must always be exactly one.<\/p>

The internal element is designed so that all its threads or teeth are in constant contact with the external element. The helical pitches of the two elements are proportionate to each cross-section, with the number of teeth. The cross-sections of the helical elements consist of coupled profiles achieved by combining epicycloids and hypocycloids, whose generator circles have a diameter equal to the distance between the longitudinal axes of the two helical elements.<\/p>

The helical winding of these profiles around their rotating axes creates volumes between the two elements, with a length equal to the pitch of the external gear. When the internal element rotates inside the external element, these volumes move without deformation along a helical path. If the helices of the external element extend over more than one revolution, the pump can discharge fluid under pressure or expand it without the need for a check valve. The pressure increases only after the first revolution of the external element’s helices.<\/p>

This motion results in the formation of “closed cavities” between the rotor and stator, which move axially from the suction side to the discharge side. Thanks to this principle, a rotating positive displacement pump is achieved that is:<\/p>
