Vertical axial flow propeller pumps are of rugged, heavy-duty construction designed to operate in a multitude of applications requiring the movement of a high volume of water at a low discharge pressure. They are used extensively for pumping water from sources including lakes, cooling ponds, tanks, rivers and oceans.

An axial flow pump, or AFP, is a common type of pump that essentially consists of a propeller in a pipe. The propeller can be driven directly by a sealed motor in the pipe or mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
The main advantage of an AFP is that it can easily be adjusted to run at peak efficiency at low-flow/high-pressure and high-flow/low-pressure by changing the pitch on the propeller (some models only).
These pumps have the smallest of the dimensions among many of the conventional pumps and are more suited for low heads and higher discharges

Applications for axial flow propeller pumps include raw water intake, dewatering, storm water removal, and flood control. These applications are found in a variety of markets including: urban and rural municipal water, government, industrial and irrigation and more.

ABS submersible mixed flow column pump AFLX 

Flows up to:
11 000 m³/h (48 000 USgpm)
Head, max:
30 m (100 ft)
 
Submersible axial flow pumps for direct installation in discharge pipes save space and installation costs. They are intended for large flows and moderate heads for storm water, land drainage and flood protection. The AFLX can handle sewage from commercial, municipal and industrial sources. Thanks to its semi-open impellers, trouble-free pumping of liquids containing solids and fibrous material is ensured. The compact units are lowered into standard steel tubes and need no anchoring. Their own weight is sufficient to hold the units securely in position. The robust design and quality materials ensure high operational reliability and hydraulic efficiency up to 88%.

                 Vertical Axial Flow Propeller Pump

Capacities: 500 to 1,000,000 GPM
Heads: 2 to 80 feet

Parameters of vertical pumping applications require the units be available in a variety of pumping configurations to meet user needs. Our suppliers meet these demands by providing pump bowls from 8" to 152" in diameter. Propeller bowls can be single-stage or double-staged in series to produce the necessary discharge pressures.

Vertical axial flow propeller pumps can be driven by vertical hollow-shaft motors,  vertical solid-shaft motors, or through right-angle gears by an internal combustion engine, steam turbine, or horizontal motors. When vertical hollow-shaft drivers are used, impeller-to-bowl clearances can be maintained with an adjusting nut located at the top of the driver. When vertical solid-shaft drivers are utilized, impeller clearance is regulated with an adjustable coupling.

               Mixed Flow Propeller Pumps

Capacities: 600 to 250,000 GPM
Heads: 1.5 to 100 feet

The successful application of vertical mixed flow propeller pumps requires the consideration of many elements. In addition to knowing the capacity and discharge head requirements.

Other factors which need to be evaluated include:

Total pump thrust
Net Positive Suction Head Available (NPSHA) and submergence
Capacity operating range
Horsepower required throughout the pump's operating range
Sump requirements

Other considerations include:

Parameters of the liquid being pumped
Allowable solid size
Type of line shaft lubrication
Type of line shaft sealing
Elevation
Driver requirements
Material of construction
