CYL Series Fluorine Lined Vertical Centrifugal Pipeline Pumps​

Product Introduction

Vertical Centrifugal Pipeline Pumps​ are a highly efficient pump type directly connected to pipelines. Featuring a vertical structural design with inlet and outlet ports aligned on the same centerline, they offer convenient installation and a compact footprint. Their fundamental principle involves an electric motor driving the impeller to rotate at high speeds, imparting energy to the liquid through centrifugal force and continuously conveying it into the pipeline system. This pump is widely used in industrial and municipal water supply/drainage, HVAC circulation, fire protection boosting, landscape irrigation, as well as liquid transfer in chemical, petroleum, and power industries. If you are seeking a pumping solution tailored to your specific application, please contact our professional team for customized proposals and quotations.

Parts

The Vertical Centrifugal Pipeline Pump consists of main components including the pump body, impeller, motor, and mechanical seal. The impeller is directly mounted on the motor's extended shaft, featuring a compact axial dimension for stable operation. The inlet and outlet ports share the same diameter and are aligned on the same centerline, facilitating installation within piping systems. The sealing assembly employs a wear-resistant mechanical seal, ensuring extended service life and convenient maintenance.

Working Principle

After the motor starts, it drives the pump shaft and impeller to rotate at high speed. Liquid enters through the center of the impeller and is flung outward by centrifugal force. It then converts into pressure energy within the volute or guide passages, propelling the liquid toward the outlet to achieve stable flow rate and head. Simultaneously, the pressure at the impeller's center decreases, creating a vacuum zone that continuously draws in fresh liquid. This enables continuous fluid conveyance, effectively elevating the medium's pressure to accomplish long-distance or high-rise water supply tasks.

Types of Vertical Centrifugal Pipeline Pumps 

Based on different media and operating conditions, vertical single-stage pipeline centrifugal pumps have evolved into multiple series:

• Clean Water Pumps: For liquids with physical and chemical properties similar to clean water (T < 80°C).
• Hot Water Pumps: Used in metallurgy, chemical processing, boilers, and heating systems (T ≤ 120°C).
• High-Temperature Pumps: Suitable for energy, chemical, and papermaking industries (T ≤ 240°C).
• Stainless Steel Chemical Pumps: Capable of conveying corrosive liquids (-20°C to 120°C).
• Pipeline Oil Pumps: Designed for petroleum products like gasoline, diesel, and kerosene (-20°C to 120°C).
• Stainless Steel Explosion-Proof Chemical Pumps: Suitable for flammable media.

Features

• The pump and motor are directly connected, with a compact structure and no need for alignment during installation.
• A variety of grinding materials to choose from, aluminum oxide vs. PTFE, silicon carbide vs. PTFE, cemented carbide vs. cemented carbide.
• Direct connection and shaft connection, no need to dismantle the pipeline for maintenance, easy to use.
• The vertical structure has the same inlet and outlet diameters, and there is no need to change the diameter. It can be connected in series, saving space. It is the first choice for pipeline pressurization of corrosion-resistant liquids.

​Uses of Vertical Centrifugal Pumps 

• Landscape Irrigation: Efficiently conveys clean water for landscaping and agricultural crop irrigation.
• Industrial and Municipal Water Supply/Drainage: Suitable for water supply, drainage, and circulating water conveyance in factories and municipal systems.
• HVAC: Used for circulating hot and cold water to ensure efficient operation of heating, ventilation, and air conditioning systems.
• Water Supply & Fire Protection: Provides stable, reliable pressurized water supply for high-rise buildings and fire protection systems.
• Other Process Applications: Widely used in petroleum, chemical, metallurgical, power, papermaking, food, pharmaceutical, and synthetic fiber industries.
• Corrosion-Resistant Conveyance: Capable of long-term conveyance of acids, alkalis, oxidizing agents, and other corrosive liquids at any concentration, with an operating temperature range of -20°C to +120°C.

Operating Conditions for Vertical Pipeline Centrifugal Pumps

1. Suction inlet pressure ≤ 1.0 MPa, or maximum system operating pressure ≤ 1.6 MPa (suction inlet pressure + head ≤ 1.6 MPa). The pump's static pressure test pressure is 2.5 MPa. If system pressure exceeds 1.6 MPa, special instructions must be provided at the time of ordering to select cast steel flow-through components and connecting parts.
2. Ambient temperature shall not exceed 40°C, with relative humidity not exceeding 95%.
3. Solid particle content in conveyed medium ≤0.1% (by volume), particle size <0.2mm. If the medium contains fine particles, specify at the time of ordering to ensure the installation of wear-resistant mechanical seals.

FAQ

1. What kind of pumps are used on pipelines?

Pipelines commonly use several types of pumps, including:

1. Centrifugal Pumps: Ideal for transporting large volumes of low-viscosity liquids, commonly used in water and chemical transfer.
2. Positive Displacement Pumps: Suitable for viscous fluids and providing accurate flow rates, often used in oil and fuel pipelines.
3. Submersible Pumps: Used in situations where the pump needs to be submerged in the fluid, such as in groundwater extraction.
4. Gear Pumps: Effective for moving viscous fluids in various industrial applications, including oil and chemical pipelines.

These pumps are selected based on the type of fluid, flow rate, and specific pipeline requirements.

2. What is an Inline Centrifugal Pump?

An inline centrifugal pump is a type of pump where the inlet and outlet are aligned in the same straight line. This design allows for easy integration into existing piping systems without requiring significant alterations. Inline centrifugal pumps are commonly used for circulating liquids in HVAC systems, water supply, and various industrial applications. They are efficient for handling low-viscosity fluids and are known for their compact size and ease of maintenance.

3. What type of pump is used to transport oil through pipelines?

The most commonly used pumps for transporting oil through pipelines are positive displacement pumps and centrifugal pumps. Positive displacement pumps are preferred for their ability to handle high-viscosity oils and provide consistent flow rates. Centrifugal pumps are also used, especially for low-viscosity oils, due to their efficiency and ability to move large volumes of liquid quickly. The choice of pump depends on the type of oil, viscosity, and specific pipeline requirements.

4. Where is centrifugal pump used?

 Centrifugal pumps are widely used in various applications, including:

1. Water Supply and Distribution: For municipal water systems and irrigation.
2. Industrial Processes: In chemical, pharmaceutical, and food processing industries to move liquids.
3. HVAC Systems: For heating and cooling applications.
4. Wastewater Treatment: To transport sewage and effluent.
5. Fire Protection Systems: For firefighting water supply.
6. Oil and Gas: For transporting low-viscosity fluids in pipelines.

Their versatility and efficiency make them suitable for many liquid handling applications.

5. What are the two types of centrifugal pumps?

The two main types of centrifugal pumps are:

1. Single-Stage Centrifugal Pumps: These pumps have one impeller and are used for applications that require low to moderate pressure. They are simple in design and suitable for transferring water or low-viscosity liquids.

2. Multi-Stage Centrifugal Pumps: These pumps have multiple impellers (stages) and are designed to generate higher pressure. They are used in applications such as boiler feedwater, high-rise building water supply, and irrigation systems.

Both types are widely used in various industries for fluid handling.
