Different Centrifugal Pump Types and Their Applications

1. Different Centrifugal Pump Types and Their Applications Introduction Centrifugal pumps are central today in various industries. There are different types of centrifugal pumps available to suit diverse industrial application requirements. These pumps are widely used for pumping, circulating, and moving fluids through the pumps from one location to another. The robust and reliable design of centrifugal pumps makes them useful for moving large volumes of fluids as well. But what types of centrifugal pumps are out there, and what are their applications? Choosing the appropriate type of centrifugal pump is essential for successful pumping operation. There are a variety of centrifugal pumps in the market with unique features, functions, and capabilities. It’s important to know about the various centrifugal pump types to ensure you select the right pump for your application.

2. In this blog, we will introduce you to the different types of centrifugal pumps, their features, technical specifications, and applications so you will know which pump suits you the best. What Is A Centrifugal Pump? A centrifugal pump is commonly used for transporting fluid in various industries by converting rotational energy into kinetic energy generated from impellers. These pumps are renowned for providing the best performance in a wide range of applications. It has unique features like energy efficiency, high operating reliability, safe fluid handling, low maintenance, heavy-duty design, high productivity, and versatility. Working Principle Of Centrifugal Pumps As mentioned above, centrifugal pumps move fluids through energy generated from impellers; let’s quickly understand the working process in detail. First, the liquid enters the centrifugal pump suction, which further moves the rotating impeller. This rotating impeller rotates through energy received from the pump motor, engine, or turbine. Centrifugal pump impellers convert rotational energy into kinetic energy and push liquid outward by centrifugal force. Lastly, fluid enters inside the volute where its velocity reduces, and pressure increases to get outside from the discharge nozzle. Different Types Of Centrifugal Pumps 1. Semi-Open Centrifugal Pump

3. Semi-open centrifugal pumps are generally pumps with semi-open impellers. It has impellers that are not covered by a shroud and are semi-open, which allows solids to pass through the impeller easily without clogging. This type of centrifugal pump is ideal for handling liquids with high solids. Features Of Semi-Open Centrifugal Pump: Maximum Interchangeability  Greater Quality Control And Accuracy  Back Pull-out Design  Exclusive Balanced Thrust  Fully Open Impeller With Back Pumps  Low Maintenance Technical Specifications:  Capacity Up to 800 m3/hr Head Up to 150 Meter Temperature 300 C Max Speed Up to 3600 rpm MOC C.I Cast Steel (Wcb), S.S 304, S.S 316 Applications Of Semi-Open Centrifugal Pump:  ETP, STP Wastewater Treatment Plant Fertilizers, Cement, And Steel Industries  Pumping Chemicals  Paper And Pulp Industries  Organic / Inorganic Chemicals 

4. Volatile Liquids  Corrosive Chemicals  Caustic Process  Effluent  Filter Press  Slurry Application  Pharmaceutical  Dyes  Textiles Kerosene  Diesel And Other Solvents 2. Side Suction Centrifugal Pump  Suction centrifugal pumps have two different types - single and double suction centrifugal pumps. Suction pumps with single suction are ideal for smaller flows, while suction pumps with double suction are suitable for large flows. Features Of Side Suction Centrifugal Pump: W/o. Mechanical Seal Gland Less Design  Dynamically Balanced Rotating Parts  Non-Clogging Semi-Open Impeller to Handle Solids  Easy Maintenance & Spares Availability 

5. Technical Specifications: Capacity Up to 100 m3/hr Head Up to 120 meter/hr Speed Up to 3000 rpm Size 25mm to 80mm Pressure Up to 12 Kg. /cm2 C.I, C.S, S.S.304, SS316/316L, Alloy-20, CD4MUC (Other MOC can be Supply on Request) Applications Of Side Suction Centrifugal Pump:  Effluent Treatment Plant MOC Dyes & Intermediates Re-Rolling Mills  Petrochemical Industries  Textile Industries  Acid  Dyes  Solvent  Organic/Inorganic Chemical  Volatile Liquids  Corrosive Chemical  Kerosene  Diesel Phosphates  Nitric  Ammonia  Condensates  Filter Press 24”, 36”, 48”, 60”, & Other Industrial Application 

6. 3. Closed Impeller Centrifugal Pump A closed impeller centrifugal pumprefers to a pump with closed impellers. Its impeller is fully covered by a shroud as it is designed with added wall sections on both the front and back sides of the vanes. Centrifugal pump with a closed impeller is suitable for fluids with low solids and high flow rates. It can not be used for pumping solids due to the risk of clogging and other wear, which can cause inefficient performance. Features Of Closed Impeller Centrifugal Pump: Maintenance Free  Superior Casting Qualities  Better Bearing Life  Highly Efficient  Chemical & Corrosion Resistant 

7. Technical Specifications: Capacity Up to 500 m3/hr Head Up to 160 meter Temperature 160 Speed 1400 to 2800 rpmm Size 25mm to 150mm MOC C.I, WCB. S.S 304, S.S 316/316L Alloy-20, CD4MCU Etc Applications Of Closed Impeller Centrifugal Pump:  Chemical And Petrochemical Sugar And Alcohol Industry  Petrochemical Industries  Boiler Feed  Circuits In Refineries & Industries  Water Supply  Irrigation  Air Conditioning  Fire-Fighting  Drainage  Circulation Of Heat Transfer Oil 
