FAQ's
for Submersible Axial Flow Pumps
-
What is an axial flow pump best suited for?
Axial flow pumps suit high-volume, low-head duties such as stormwater, flood control, irrigation and wastewater transfer.
-
How is an axial flow pump different from a centrifugal pump
Axial flow pumps prioritise very high flow at low pressure, while centrifugal pumps are generally better suited to higher-head duties.
-
What is the maximum flow available?
The RSX Series provides up to 1,333 L/sec, depending on the selected model and operating duty.
-
What installation options are available?
Selected RSX models are available in free-standing and well-type configurations.
-
Can these pumps handle solids
Smaller RSX models provide solids passage from 20–23 mm; larger-model intake conditions should be reviewed for the application.
-
What monitoring and protection options are available?
Options include condition monitoring, bearing thermal protection, seal probes, thermal motor protection and special coatings.
-
Are these pumps suitable for seawater?
Selected configurations can be supplied with special coatings and zinc anodes for seawater installations.
-
How do I select the right axial flow pump?
Selection depends on required flow, operating head, installation type, water quality, solids and site conditions.
