all parts of centrifugal pump|centrifugal pump selection chart : makers Priming is the initial phase of a centrifugal pump’s operation. The process of priming involves filling the pump’s suction pipe casing with the liquid to be pumped and positioning the fluid … See more Twin screw pumps are a type of positive-displacement pump that uses two screws to move liquids or solids along their axis. They are often used in sanitary processing systems, where they offer several advantages over centrifugal pumps, such as reduced damage to pumped products due to lower turbulence and pulsation, and the ability to pump fluids with significantly .A screw pump is a type of pump that uses a set of screws to pump fluid from one area to other. Ituses one or more screws to move fluids or water along the axis of the screw. The screws of the pump are interlocked to pressurize the fluid and move it inside the system. These screws are meshed with each other . See more

SEIM screws pumps are positive displacement volumetric self-priming pumps suited to handle various oils and fluids with a minimum lubricating property. The pumps design and .
Different types of centrifugal pumps are widely used in various industries worldwide. These pumps are classified based on the number of impellers, type of casing, orientation, and position. Understanding the various parts of a centrifugal pump is essential for proper maintenance, troubleshooting, and efficient operation. Let's delve into the different components that make up a centrifugal pump.
It is one of the simple and exciting topics in fluid mechanics.What is the need for a pump? We require a pump to transmit water from a region of low pressure to a region of higher pressure. The centrifugal pump defines as a hydraulic machine that converts mechanical energy into hydraulic energyby means of a
Based on the Number of Impellers
# 1. Single Stage Impeller
A single-stage centrifugal pump has only one impeller mounted on the shaft. This type of pump is commonly used for low-pressure applications where a single impeller is sufficient to achieve the desired flow rate. The impeller is the primary rotating component of the pump responsible for imparting energy to the fluid.
# 2. Multi-Stage Impeller
In contrast to single-stage pumps, multi-stage centrifugal pumps feature multiple impellers stacked in series on the same shaft. Each impeller increases the pressure of the fluid as it passes through, allowing for higher pressure applications. Multi-stage pumps are commonly used in high-pressure systems such as boiler feedwater, reverse osmosis, and irrigation.
Centrifugal Pump Parts and Functions
# 1. Casing
The casing is the outer shell of the centrifugal pump that encloses the impeller and volute. It serves to contain the fluid being pumped and directs the flow towards the discharge outlet. Casings can be of various types, such as volute, diffuser, or axial flow, depending on the specific pump design.
# 2. Impeller
The impeller is a rotating component with vanes that transfer mechanical energy to the fluid by spinning at high speeds. The design of the impeller plays a crucial role in determining the pump's performance characteristics, such as flow rate, head, and efficiency.
# 3. Shaft
The shaft connects the motor to the impeller and transmits the rotational motion from the motor to the impeller. It must be properly aligned and supported to ensure smooth operation and prevent excessive vibration.
# 4. Bearings
Bearings support the shaft and impeller, allowing them to rotate freely with minimal friction. Proper lubrication and maintenance of bearings are essential to prevent premature wear and ensure long-term reliability.
# 5. Seal
Seals prevent leakage of fluid from the pump and maintain the pressure within the system. Common types of seals used in centrifugal pumps include mechanical seals, packing seals, and lip seals.
# 6. Suction and Discharge Ports
The suction port is where the fluid enters the pump, while the discharge port is where the pressurized fluid exits the pump. Proper alignment and sizing of these ports are critical for efficient operation.
# 7. Motor
The motor provides the power necessary to drive the pump and rotate the impeller. Motors can be electric, diesel, or steam-powered, depending on the application requirements.
Centrifugal Pump Selection Chart
When selecting a centrifugal pump for a specific application, various factors must be considered, including the flow rate, head, efficiency, and NPSH (Net Positive Suction Head) required. Refer to the centrifugal pump selection chart to determine the most suitable pump for your needs based on these parameters.
