Two Main Categories

Positive Displacement Pumps

Deliver a fixed volume per stroke/rotation. Flow is proportional to speed.

• AODD pumps
• Metering pumps
• Screw pumps
• Lobe pumps

Centrifugal Pumps

Use rotating impeller to create flow. Flow varies with pressure.

• Monoblock pumps
• Submersible pumps
• Self-priming pumps
