Open Well Pumps Comparisons

Centrifugal pump which operates in a horizontal position.

Multistage centrifugal pump which operates in a vertical position.

Pushes water from the source to the surface using the impeller.

Pump pushes water to the surface by converting rotary energy into kinetic energy into pressure energy.

Pump in submerged inside the water, therefore no space on land is required.

Pump in submerged inside the water, therefore no space on land is required.

• Works well where application requires a high discharge of water.
• Easy to repair.
• Submerged so no additional space required.

• Efficient power consumption.
• Works well where high head application is required.
• No priming required.
• Quiet operation.

• Can only work up-to a limited depth.
• Limited to horizontal installation (vertical installation leads to shaft bending).
• Can't process solid particles.

• Can produce dry runs when water levels low (e.g. during summer)
• Hard to handle when needing repairs.
• Can allow entry of sand from the water source.
• Can't process solid particles.
