PUMPING UNITS

1. Beam Pumping Units (Rod Pumps / "Nodding Donkeys")

• Function: Reciprocating pump for artificial lift (sucker rod systems)

• Components:

  • Prime mover (electric motor or gas engine)

  • Walking beam & horsehead

  • Counterbalance & gearbox

• Applications: Onshore oil production (conventional wells)

2. Hydraulic Fracturing Pumps (Frac Pumps)

• Function: High-pressure fluid injection for shale stimulation

• Features:

  • 2,000–15,000+ HP

  • 5,000–20,000 PSI pressure rating

  • Quintuplex or triplex plunger designs

• Applications: Fracking, cementing, acidizing

3. Mud Pumps (Drilling Circulation Pumps)

• Function: Circulate drilling fluid in rotary drilling

• Types:

  • Triplex (3-cylinder) – Most common

  • Duplex (2-cylinder) – Older designs

• Pressure Range: 3,000–7,500 PSI

4. Submersible Pumps (ESP/Electric Submersible Pumps)

• Function: Downhole electric pumps for high-volume lift

• Components:

  • Multistage centrifugal pump

  • Downhole motor & seal section

  • Power cable & surface VSD controls

• Applications: High-water-cut wells, offshore production

5. Chemical Injection Pumps

• Function: Precise dosing of production chemicals

• Types:
