Replace Franklin axial flow pump Introduction
 
Since the trace of the fluid micro-group flowing through the impeller is theoretically located on the cylindrical surface concentric with the rotating shaft, and the outflow is considered to be along the axial direction after the guide vane derotation, this pump is called an axial flow pump, also known as a Kaplan pump. The flow rate of the axial flow pump is large, up to 60m3/s; the single-stage head is low, usually 1~25m. Therefore, the specific speed of the axial flow pump is high, and its common range is between 500~1600.
 
Replace Franklin axial flow pump Features
 

• ① Simple structure, under given working parameters, the cross-sectional area (plane perpendicular to the rotating shaft) and weight are smaller than other types of vane pumps;
• ② Whether in shutdown or running state, the flow rate can be easily changed by changing the blade placement angle;
• ③ Axial flow pumps are usually vertical structures, so they occupy a small area and can also be installed outdoors.

 
Replace Franklin axial flow pump Application
 
Axial flow pumps are widely used in irrigation, water supply and drainage, inland waterway dredging, power engineering and other fields that require large amounts of liquid to be transported but do not require high head. They are also used in nuclear power engineering and ship propulsion.

1. How efficient are axial flow pumps?

Yes, axial flow pumps are known for their high efficiency, and can move large amounts of fluid with relatively low energy consumption. Their design minimizes energy losses and maximizes hydraulic efficiency, especially when close to the best efficiency point (BEP).

Of course, correct sizing, selection, and maintenance are essential to achieving high efficiency. When the equipment is first specified, operating conditions and system design must be considered to improve efficiency.

2. How do axial flow pumps differ from other pump types?

Axial flow pumps work differently from other types of pumps, such as centrifugal pumps, and do not waste energy when changing the direction of fluid flow, thereby improving efficiency. All pumps convert mechanical/electrical energy into fluid kinetic energy, which manifests as velocity or pressure head. However, the machine form changes the nature of these conversions.

The fluid moves parallel to the pump shaft, and the impeller blades impart axial velocity to the fluid, rather than requiring forceful rotation as in centrifugal pumps. In most centrifugal pumps, the fluid moves radially from the center of the impeller to the outside, generating centrifugal force. The fluid enters the pump axially and exits radially, making a turbulent and energy-consuming 90° turn.

Axial flow pumps are designed to achieve high flow rates at relatively low heads, delivering large volumes of fluid with minimal pressure increase. Centrifugal pumps are typically suitable for a wide range of flow rates and heads, depending on the specific design and impeller configuration. Centrifugal pumps can handle moderate to high flow rates and have higher output pressures than typical axial flow pumps.

Axial flow pumps are typically used for high flow rates and low heads. Centrifugal pumps are more versatile and can be used in applications that require a balance between flow and delivery pressure.
