A single-stage centrifugal pump is a centrifugal pump with one impeller that creates centrifugal force to move fluid from a low-pressure area to a high-pressure area, used for applications requiring lower to moderate head and flow rates. Its simple design, with fewer moving parts, makes it cost-effective, easy to maintain, and suitable for a wide range of common applications, including water supply, HVAC, and various industrial processes.

Advantages of Single-stage Centrifugal Pump
Simplicity in Design
Their straightforward design makes them easy to install, operate, and maintain. This simplicity reduces downtime during maintenance activities.
Cost-Effectiveness
Generally less expensive than multi-stage pumps, making them suitable for budget-conscious projects while still delivering reliable performance.
High Flow Rates
Capable of delivering large volumes of fluid at low to moderate pressures efficiently. This feature is particularly beneficial in applications requiring rapid fluid movement.
Versatility
Suitable for various applications across different industries due to their adaptability to different fluid types. They can handle clean water as well as more viscous liquids depending on design specifications.
Close-coupled - Where the pump head and motor are directly connected without a coupling. Close Coupled Centrifugal Pump.
Long-coupled – Where the pump and motor are mounted on a base plate and connected via a coupling.
Vertical Inline - Pump is mounted Vertically for space saving. Vertical inline pumps can be close coupled of long coupled when fitted with a spacer bracket.
Applicable of Single-stage Centrifugal Pump
Large flow and low head water supply
Such as agricultural irrigation and primary water supply in water plants. Single-stage pumps have higher efficiency than multi-stage pumps due to the lack of impeller series resistance.
Limited space or mobile scenarios
Small factory supporting, vehicle-mounted emergency water supply pumps, single-stage pumps are smaller in size than multi-stage pumps, and installation and maintenance are more flexible.
Home and small commercial applications
Such as home tap water boosting, small air conditioning circulation system, laboratory low-head liquid transportation, single-stage pumps are simple to operate, low in energy consumption, and can meet daily low-pressure needs.
To operate properly, a standard centrifugal pump relies on several key components:
Impeller
The impeller is attached to the shaft and spins at the same speed as the shaft, powered by a motor, engine, or hydraulic unit. As fluid enters the impeller's eye, it passes through the vanes, gaining velocity and kinetic energy. By the time the fluid exits the impeller and enters the casing, its velocity matches the impeller's rotational speed.
Diffuser or Volute Casing
The diffuser or volute casing is responsible for containing the fluid and generating fluid pressure. It slows down the fluid's velocity upon entry, converting velocity into pressure.
Shaft and Shaft Sleeves
The shaft is the central part of the pump's rotor system. It supports the impellers, mechanical seal, and bearings. The shaft provides a rigid framework for pump operations.
Bearings
Bearings support the shaft and other rotating components within the pump's housing. They absorb radial and axial forces during pump operation, maintaining shaft alignment for peak efficiency and reliability. Types of bearings used include anti-friction bearings, pivoted-shoe thrust bearings, and sleeve bearings.
Mechanical Seals
Mechanical seals or packings prevent the pumped fluid from leaking along the rotating shaft. They are housed within the casing cover at the back of the pump casing. The type of seal used depends on factors like the process fluid, operational temperature, and pressure.
