AODD pumps for water & wastewater
Treatment-chemical transfer and sludge transfer are different duties. Start with the liquid composition and solids rather than choosing a pump from the industry name alone.
Define the transfer duty
Identify whether the pump will move a pH-adjustment chemical, a coagulant, wash water or a solids-bearing stream. Include the required flow at the actual discharge pressure, suction lift and operating schedule in the enquiry.
Review every wetted material
Polypropylene is a candidate for compatible treatment chemicals, not a universal wastewater material. Check chemical concentration and temperature against the body, diaphragms, balls, seats and seals. Abrasive sludge also needs a solids-size and wear assessment.
Bolted or clamped construction
Compare joint sealing, access for cleaning and the maintenance procedure for the specific model. A bolted plastic configuration is a starting point for review; neither its colour nor its joint type proves chemical compatibility.
Configurations to discuss
These are candidate families for a duty review, not a guaranteed material recommendation.
Send your operating requirements
Include fluid composition, concentration, temperature, viscosity, solids, required flow, discharge pressure, suction conditions and cleaning method.
