Q.
What are the best materials to use in pump construction to minimize part corrosion?
More than 15 years ago, a 160 in plate mill was experiencing significant maintenance problems with its descaling pumps; the typical mean time between repairs was only 6 to 8 months. Some rebuilt pumps even failed on start-up.
Organizations affected by regulatory requirements to remove lead from pipes, faucets and plumbing fixtures are likely well-down the path of investigating material options to adhere to new legislation. Organizations not directly affected by legislation should still take a broader view and consider how "getting the lead out" could deliver benefits to their business.
Compared to conventional biological wastewater treatment systems, submerged membrane bioreactors (MBR) produce significantly improved effluent quality and have a substantially smaller footprint.
I have seen, and I am sure you have to, countless examples of installed pumps that are poor hydraulic fits. These selection mistakes are called off-design pump selections, bad actors, misapplied pumps, etc.

Much has been reported recently about surface water reservoirs in the Southeast and West maintaining dangerously low levels.
Basically, a repair is the simplest, least-involved way of "fixing" a pump, typically caused by a non-recurring accidental event, such as a broken shaft, failed seal, and so on. An overhaul is more involved.
