Pumps for Oil & Gas Applications
Pumps in oil and gas handle crude oil, refined products, and process fluids. API 610 defines requirements for centrifugal pumps, while API 674/675/676 cover positive displacement types.
Common Equipment
Crude transfer pumps, injection pumps, pipeline booster pumps, loading arm pumps, firewater pumps
Selection Criteria
API compliance, NPSH requirements, material compatibility, seal system selection, driver sizing
Compliance Notes
API 610 11th edition for centrifugal, API 674 for reciprocating, API 676 for rotary. ATEX/IECEx for hazardous areas.
Part Types
Centrifugal Pumps
Centrifugal pumps move fluid using rotational energy from impellers. Most common pump type for water and low-viscosity fluids.
Diaphragm Pumps
Diaphragm pumps use flexible membrane displacement for pumping. Ideal for abrasive, viscous, and chemical fluids.
Gear Pumps
Gear pumps use meshing gears to pump fluid. Provide smooth, pulse-free flow for lubricants and fuels.
Metering Pumps
Precise chemical dosing
Peristaltic Pumps
Tube compression for sterile transfer
Piston Pumps
Reciprocating action for high pressure
Positive Displacement Pumps
Positive displacement pumps move fixed volumes of fluid per cycle. Provide consistent flow regardless of pressure.
Screw Pumps
Helical rotors for viscous fluids
Submersible Pumps
Submerged operation for wells and tanks
Vacuum Pumps
Create and maintain vacuum conditions
