Pump Types

🔽

Submersible Pumps

Most common for boreholes, motor and pump submerged in water

Depth: 10m - 500m
Flow: 0.5 - 500 m³/hr
Efficiency: 50-75%
🔄

Surface Centrifugal Pumps

Surface-mounted, for shallow wells and water transfer

Depth: 0 - 8m suction
Flow: 1 - 2000 m³/hr
Efficiency: 60-85%
💨

Jet Pumps

Surface pump using ejector, for medium depth wells

Depth: 0 - 60m
Flow: 1 - 10 m³/hr
Efficiency: 30-50%
☀️

Solar Pumps

DC or AC pumps powered by solar panels, for off-grid locations

Depth: 10 - 200m
Flow: 0.5 - 50 m³/hr
Efficiency: 40-70%
✋

Hand Pumps

Manual operation, for rural areas without electricity

Depth: 0 - 45m
Flow: 0.5 - 1.5 m³/hr
Efficiency: N/A (manual)
🐍

Progressive Cavity Pumps

Positive displacement, for viscous fluids and solids handling

Depth: 0 - 100m
Flow: 0.1 - 200 m³/hr
Efficiency: 50-80%
