Variable-Speed Wastewater Pumping

During the last 10 to 15 years, the industry has seen a significant increase in the adaptation of variable frequency drives (VFDs) in wastewater transport systems. A general desire is to better control the wastewater flow through the pump stations. Variable-speed systems can provide a more flexible and powerful solution compared to using constant-speed pumps.

Material Selection for Wastewater Pumps: Raise Performance and Extend System Lifetime

Wastewater can sometimes be both corrosive and abrasive. Selecting the most suitable material for wastewater pumps is therefore crucial to obtaining a reliable, long-lasting and cost-effective operation. This paper provides recommendations for suitable wastewater pump materials and protection for use with different media. It also describes various phenomena associated with corrosion and abrasion.
