The heads used in mechanical pumping systems are high resistance mechanical elements to traction, friction and tension, they are made of a pair of keyholes to Steel molten heads, connected by a Steel center string and head anchor system through the providing material application of high purity.
This system connects the superficial mechanical system and the extraction system (string of bars) which are in the underground and they depend of the unit capacity, being 322-640 or 912 from the mechanical pumping system, it is necessary to install a head system from 16ft to 48ft.
