Axial Flow Pump

Vertical Axial Flow Pump

The Vertical Axial Flow Pumps are the ideal pumping device for the applications of big flow rate and relatively discharge pressure. Compared to horizonal type, the vertical design minimizes footprint a lot by fully immersed the pump casing into the fluid in the tanks or sumps. Therefore, the Vertical Axial Flow Pump is suiable for places where the space is restricted. Those pumps have advantages like space-saving, robust pump construction and optimized hydraulic models. Due to the vertical structure design, it simplifies the daily maintenance of both pump and electric motor, making those veritcal axial flow pumps the cost-saving and pratical solution for heavy duty and large volume applications. Those pumps can work with both clean water or corrosive fluids, so they are widely used in flood control, irrigation, water treatment plants, seawater desalination plants, dry docks, chemical plants...

Performance

The Vertical Axial Flow Pumps can be used in various application, and base on the different requirements, we developed a wide performance range as follows:

■ Flow rate: Q=300～38,000 （m³/h）

■ Total head: H= 1～300 (m)

■ Speed: n=180-1450rpm

■ Fluid temperature: T= 0～150℃

■ Fluid s.g.: γ≤1.4

■ Vertical Space-Saving Design: The pump and motor are arranged vertically, typically submerged in the fluid source. This compact configuration significantly reduces the required floor space and footprint compared to horizontal pumps, making it ideal for confined areas such as sumps, pits, and tanks.

■ High-Flow, Low-Head Efficiency: This pump is specifically engineered to efficiently move very large volumes of fluid (high flow) against low system resistance (low head). Its hydraulic profile is optimized for applications where lifting fluid over a short height at a high rate is the primary requirement.

■ Robust Construction for Demanding Environments: Designed for continuous, heavy-duty service, these pumps are often built with durable materials like stainless steel, cast iron, or specialized alloys to withstand harsh conditions, including raw water, mildly corrosive liquids, and abrasive suspensions.

■ Straight-Thru Axial Flow Path: The impeller directs the fluid parallel to the pump shaft (axially), resulting in a straight-through discharge. This streamlined flow path minimizes hydraulic losses and turbulence, contributing to high operational efficiency and reduced energy consumption.

■ Simplified Installation & Maintenance: The design often eliminates the need for complex foundations, baseplates, and coupling alignment. Many models feature a discharge elbow that is supported separately, allowing the entire rotating assembly to be lifted vertically for easy inspection and maintenance without disturbing the main pipeline.

■ Reliable Operation: With minimal rotating components and a design less prone to clogging, vertical axial flow pumps offer high reliability and long service intervals, ensuring stable performance in critical applications like flood control and continuous process cooling.
