ASW
ASW Submersible Sewage Pump
ASW is a submersible sewage pump for wastewater collection, drainage and transfer. The pump operates in the liquid; its passage must suit the solids and fibres present.
- municipal sewage
- industrial wastewater
- rainwater
Sewage & Wastewater Pumps
Submersible and self-priming pumps for wastewater.
Compare ASW submersible sewage pumps and AZW self-priming wastewater pumps for drainage and effluent transfer. Match the liquid, solids, installation and wetted materials to the duty.
Compare wastewater pump arrangements
ASW works submerged in the collection area; AZW draws through an inlet line. The stainless-steel ASW version adds a material choice that must suit the wastewater.
ASW Stainless Steel
ASW Stainless-Steel Submersible Sewage Pump
The stainless-steel ASW version provides a different material choice for suitable corrosive wastewater. Compatibility depends on the stainless grade, liquid chemistry and temperature.
- chemical wastewater
- industrial effluent
- corrosive drainage
AZW
AZW Self-Priming Non-Clog Sewage Pump
AZW uses a self-priming arrangement to transfer sewage and wastewater through an inlet line. The suction route is an important difference from a pump working submerged in the collection area.
- municipal wastewater
- aquaculture
- papermaking

Building drainage
Mining drainage
Chemical wastewater
Wastewater and the collection area
The liquid, solids and fibres affect the wet end. The collection area and inlet line determine whether a submerged or self-priming layout fits the site.
- Wastewater source, composition and temperature
- Maximum solids size and fibre content
- Required flow and head
- Collection-pit levels or suction-pipe details
- Installation access and power supply

Sewage Pumps questions
How do ASW and AZW differ as pump types?
ASW operates submerged in the liquid; AZW uses a self-priming arrangement. Solids, fibres, liquid chemistry and installation still require review. Stainless-steel ASW is not a universal corrosion solution.
How do submersible and self-priming wastewater pumps differ?
ASW places the pump and motor in the liquid. AZW uses a self-priming arrangement with suction conditions that still need checking. Compare the wastewater, solids, liquid levels, pipework and maintenance access before selecting a model.
What equipment and documents should I request?
Specify the pump, drive, controls, accessories, spare parts and technical documents you need. The final configuration and supply scope are confirmed in the quotation.
