A frac pump (fracturing pump) is a high-pressure pump used in hydraulic fracturing (fracking) for oil and gas extraction. It is designed to inject a mixture of water, sand (proppant), and chemicals into underground rock formations at extremely high pressure to create fractures, allowing oil and gas to flow more freely.

Key Features of a Frac Pump:

1. High Pressure & Flow Rate – Typically operates at 5,000 to 15,000 psi with flow rates ranging from 2,000 to 3,500 GPM (gallons per minute).

2. Triplex or Quintuplex Plunger Design – Uses three or five plungers to generate consistent pressure.

3. Heavy-Duty Construction – Built to withstand extreme conditions in oilfield operations.

4. Diesel or Electric Power – Driven by large diesel engines (e.g., CAT or Cummins) or electric motors.

5. Modular Skid or Trailer-Mounted – Allows easy transportation and deployment in remote locations.

Types of Frac Pumps:

1. Triplex Pumps – 3-plunger design, commonly used in medium-duty operations.

2. Quintuplex Pumps – 5-plunger design, offering smoother operation and longer lifespan.

3. Electric Frac Pumps – More environmentally friendly, with lower emissions and reduced fuel costs.
