2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

3. Automatic lubrication system - Wikipedia

   en.wikipedia.org/wiki/Automatic_lubrication_system

   When the system is started, a pump increases the pressure of lubricant throughout the system to a set point. A pressure switch signals the control system that lubricant has been applied at all the lubricant distribution points have been reached. The pump stops, pressure is vented from the system and the lubricant is directed back to the pump ...

4. Pumping (oil well) - Wikipedia

   en.wikipedia.org/wiki/Pumping_(oil_well)

   In the context of oil wells, pumping is a routine operation involving injecting fluids into the well. Pumping may either be done by rigging up to the kill wing valve on the Xmas tree or, if an intervention rig up is present pumping into the riser through a T-piece (a small section of riser with a connection on the side).

   en.wikipedia.org/wiki/Total_dynamic_head

   In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
