Vertical Axial Flow Pump

Vertical Axial Flow Pump – Denwell Fluid Controls

Denwell Fluid Controls manufactures and supplies industrial axial flow pumps designed for high-flow, low-head applications. Its product range includes both horizontal and vertical configurations. The company identifies itself as a manufacturer and exporter of industrial centrifugal pumps and axial flow pumps for applications including water treatment, chemical processing, food & beverage, and other industrial requirements.

Vertical Axial Flow Pump

The Vertical Axial Flow Pump from Denwell Fluid Controls is designed for applications where very large volumes of liquid need to be moved at relatively low heads. Unlike conventional centrifugal pumps that primarily move liquid radially, an axial flow pump uses a propeller-type impeller to move fluid substantially parallel to the pump shaft.

The vertical configuration can be suitable for large water-handling installations where space, intake arrangement, liquid level, and high-volume circulation requirements make vertical pump installation practical.

Denwell's published axial-flow range states flow capacity up to 25,000 m³/hr and head up to 10 metres, with vertical and horizontal mounting options. Published material options include cast iron, stainless steel and alloy steel depending on application.

Q&A – Vertical Axial Flow Pump

1. What is a Vertical Axial Flow Pump?

A Vertical Axial Flow Pump is a pump designed to move large volumes of liquid at comparatively low heads. Its propeller-type impeller moves the liquid primarily parallel to the pump shaft.

2. How does a Vertical Axial Flow Pump work?

Liquid enters the pump and is accelerated by the rotating propeller-type impeller. The resulting flow travels substantially in the axial direction, allowing the pump to handle high volumes of liquid efficiently.

3. What is the main advantage of an axial flow pump?

Axial flow pumps are particularly suited to applications requiring very high flow rates at relatively low heads. Denwell describes its axial flow pumps specifically for very high-flow and low-head applications.

4. Why is the pump installed vertically?

A vertical arrangement can be advantageous for large water-handling systems where the pump intake and liquid level require a vertical configuration. The appropriate arrangement depends on the installation design and operating conditions.

5. What is the flow capacity of Denwell's Axial Flow Pump?

Denwell's published axial-flow pump range states a flow capacity of up to 25,000 m³/hr and a head range of up to 10 metres.

6. Where are Vertical Axial Flow Pumps commonly used?

They can be considered for cooling-water circulation, condenser systems, irrigation, flood control, desalination, water treatment, large water intake and discharge systems, MEE plants and biogas applications.

7. Can a Vertical Axial Flow Pump be used for water treatment applications?

Yes. Denwell lists water treatment among the applications for its industrial pumping solutions and includes water-treatment-related duties within its axial-flow applications.

8. Is a Vertical Axial Flow Pump suitable for high-head applications?

Axial flow pumps are primarily intended for high-flow, low-head duties. When an application requires substantially higher head, another pump configuration may be more appropriate. Final selection should be based on the required flow and head.

9. What materials are available for Denwell Axial Flow Pumps?

Denwell's published information lists Cast Iron, Stainless Steel and Alloy Steel as material options depending on the application.

10. Can the pump be used for continuous operation?

Denwell specifies its axial-flow pump offering for continuous-duty applications. Actual continuous operation should be evaluated against the selected pump's duty point, liquid characteristics and installation conditions.
