The single-stage centrifugal pumps are the most common and simplest type of centrifugal pumps. 

The Single-stage Centrifugal Pumps are versatile and widely used pumps designed to move and transfer liquids, typically water or other fluids. It operates on the principle of centrifugal force to effectively and efficiently transport fluids from one place to another. At their core, these pumps are valued for their simplicity, high efficiency, smooth flow output, and capacity to handle large volumes of low-to-medium viscosity fluids, such as water, chemicals, and light oils.

Advantages

• Simple Design: Fewer parts lead to lower initial cost, easier maintenance, and robust operation.
• High Flow Rates: Excellent for applications requiring substantial volumetric flow.
• Smooth, Continuous Flow: Delivers a steady, non-pulsating flow.
• Compact and Versatile: Available in a vast range of sizes, materials, and configurations to handle diverse fluids (water, chemicals, light oils, etc.).
• Generally Low to Moderate Pressure: Generates pressure in a single stage; for very high pressures, multi-stage pumps are required.

Applications

• Due to their versatility and efficiency, single-stage centrifugal pumps are used across countless industries:
• Water Supply & Irrigation: Municipal water systems, building services, and agricultural irrigation.
• HVAC Systems: Circulating hot and chilled water in heating and cooling systems.
• Industrial Processes: Transferring process water, solvents, and mild chemical solutions.
• Fire Protection Systems: As part of fire water ring mains and sprinkler systems.
• Wastewater & Drainage: Handling low-viscosity effluents and stormwater.
   

Centrifugal single-stage pumps are commonly used in several industries, and this is because of their efficiency as well as reliability. Single-stage pumps have fewer components, which reduces wear and tear and extends equipment life, lowering maintenance costs.
