Product Details

Submersible axial flow pumps are device that moves fluid in a direction parallel to the pump shaft. The rotating impeller with curved blades pushes water forward. The fluid flows along the axis to gain energy from the rotation of impeller.

MODEL MEANING

Series Code

QZ-impeller adjustable submersible axial-flow pump
QH-impeller adjustable submersible mixed-flow pump

Example:350QZ(H)35G(D)

350	Nominal release aperture
QZ(H)	Submersible axial-flow pump(submersible mixed-flow pump)
35	1/10 of the specific number of revolution
G	Equal specifie number of revolutions and nominal release aperture rotating speed at a higher shift
(D)	Equal specific number of revolutions and nominal release aperture rotating speed at a lower shift

Axial flow pumps are used within a special parameter ranges, typically handle large flow rates, from 50 to 30,000 m³/h, but with low heads, usually between 1 and 20 meters. Their power can range from 1.5 kW to over 1,000 kW, depending on the specifications.

Features

Submersible axial flow pumps are widely used in working condition needing high flow but low pressure. Common applications include irrigation systems, drainage projects, and cooling water circulation in power plants. They also work in wastewater treatment plants to move large volumes of liquid efficiently.

The main materials of axial flow pumps vary by condition. The impeller and casing are often made of cast iron or stainless steel for a long service life. Bronze or plastic may be used to resist rust and damage for corrosive fluids.
In structure, submersible axial flow pumps include a motor, a rotating impeller, a stator and a casing. The motor drives the impeller, which is surrounded by the stator to ensure smooth fluid movement. Some models have adjustable blades to change flow rates easily.
