All pump types have their advantages and disadvantages, but some are more effective for a particular application than others. View the comparative chart below. Though not exhaustive, it details 14 types of pumps. For even more information on the pumps (such as specific flow rates, if they handle particulates, run dry, and more), go to metering pumps, transfer pumps, centrifugal pumps, hand and drum pumps, peristaltic pumps, and positive displacement pumps.
Pump Type | Max Pressure | Self-Priming | Pulseless Flow | Fluid Viscosity | Advantages |
Air-Operated Diaphragm | Up to 87 psi | Excellent | Fair | Medium | Low flow, simple operation with one diaphragm.Ideal for OEM or end-use applications. |
Bellows | Up to 73 psi | Good | Poor | Medium | Can pump liquids or gases |
Centrifugal | Up to 363 psi | Poor | Excellent | Light | Fluid transfer at high flow rates and low pressures |
Diaphragm | Up to 300 psi | Good | Poor | Medium | High-accuracy; for applications such as pH/ORP control |
Dispensing | Up to 125 psi | Good | Poor | Medium | Accurate, reproducible flow |
Drum | Up to 100 psi | Poor | Excellent | Medium | Economical. No electrical parts |
Gear | Up to 100 psi | Poor | Excellent | Medium | Pulseless flow at high pressures |
Masterflex® Peristaltic | Up to 125 psi | Excellent | Fair | Heavy | Noncontaminating; available in a wide variety of pump materials |
Microfluidics | Up to 6000 psi | Fair | Excellent | Medium | Low-flow precision fluid distribution |
Peristaltic (Other) | Up to 125 psi | Excellent | Fair | Heavy | Noncontaminating |
Piston | Up to 5000 psi | Good | Poor | Medium | Highest pressure and accuracy; ideal for HPLC applications |
Progressing Cavity | Up to 360 psi | Fair | Excellent | Very heavy | Pulseless flow for highly viscous or particulate-laden fluids |
Pump Systems | Up to 100 psi | Good | Excellent | Excellent | Complete systems configured to your exact needs |
Roller | Up to 50 psi | Excellent | Excellent | Medium | For high-temperature applications where some particulates are present |
