Type: Rotodynamic pump (centrifugal type)
Load: Primarily hydraulic load from fluid movement; radial and axial forces on impeller
Cage: Not applicable (no rolling element cage; uses impeller and shaft system)
Performance: Steady flow, moderate to high efficiency, best for low-viscosity fluids
Construction: Casing, impeller, shaft, seals, bearings, and drive motor
Use cases: Water transfer, irrigation, HVAC systems, industrial fluid movement, cooling circuits
Note: Requires proper priming before operation; avoid dry running and ensure correct sizing for best efficiency

Type: Air-Operated Double Diaphragm (AODD) pump
Load: Handles fluid pressure loads; suitable for low to medium pressure transfer applications
Cage: Not applicable (uses flexible diaphragms instead of rolling elements)
Performance: Steady flow, self-priming, can run dry, handles solids and viscous fluids well
Construction: Dual diaphragm chambers, air valve system, check valves, and fluid housings (metal or plastic options)
Use cases: Chemical handling, slurry transfer, oil and fuel movement, wastewater, coatings, and industrial processing
Note: Requires clean, regulated compressed air; efficiency depends on air supply quality and proper diaphragm material selection

Type: Gear pump (external or internal gear type)
Load: Handles hydraulic pressure loads; designed for steady fluid displacement
Cage: No cage; uses meshing gears supported by bearings/bushings
Performance: Steady flow, moderate pressure capability, efficient with viscous fluids
Construction: Housing + driving and driven gears + shafts + seals; close-clearance design
Use cases: Hydraulics, lubrication, fuel transfer, oil circulation, industrial fluid systems
Note: Requires clean fluid and proper lubrication; avoid dry running to prevent damage

Type: Reciprocating piston pump (positive displacement)
Load: Handles high-pressure loads with steady flow output
Cage: Not typically cage-based; uses piston, seals, and valve assemblies
Performance: High efficiency, accurate flow control, capable of very high pressures
Construction: Cylinder block, reciprocating piston, inlet/outlet valves, seals, and drive mechanism
Use cases: Hydraulic power units, chemical injection, pressure cleaning, oil transfer, industrial fluid systems
Note: Requires regular seal maintenance and clean fluid supply; not ideal for highly abrasive or contaminated fluids without proper filtration

Type: Submersible pump (water/sewage/deep well types)
Load: Handles hydraulic load based on fluid head and flow demand
Cage: Not applicable (sealed motor and impeller assembly)
Performance: High efficiency, consistent flow, self-priming due to submerged operation
Construction: Sealed motor housing, impeller, shaft, mechanical seals, and waterproof cable
Use cases: Borewells, drainage pits, sewage systems, irrigation, construction sites
Note: Must remain submerged during operation for cooling; running dry can damage the pump
