How often does your submersible pump wear out and need to be replaced? Are chronic pump failures taking up too much of your maintenance team’s time? Corrosive materials in the water you are pumping can cause these issues and more. Corrosive fluids are common in many wastewater applications, including chemical plants, food/beverage production, metal plating operations, paper processing, etc. If you’re experiencing more downtime or higher maintenance/repair costs, a stainless steel submersible pump may cure these common headaches.
Many substances dissolved in common wastewater fluids can be highly corrosive when pumps are exposed to them for extended periods. The higher the concentration of these substances in a liquid, the worse the corrosion will be. Some common examples include salt, sodium hydroxide (better known as lye or caustic soda), phosphoric and nitric acids, sodium hypochlorite (bleach), chlorine, peracetic acid, and hundreds of others.
The manufacturing environment can be hard on equipment, and pumps are no exception. This was the scenario at a custom metal manufacturing facility in the Northeast where the pumps were failing repeatedly. After numerous work stoppages and costly replacement expenditures, the manufacturer finally turned to Midway Industrial Supply for help finding a solution to the ongoing problem.
Midway Senior Account Manager Lenny Klein was tasked with finding a solution. He took it upon himself to gain a full overview of the problem — how many gallons per minute were moving through the nearly continuously running pumps, how many feet of head needed to be pumped, and the piping configuration. before recommending a BJM SK Series submersible shredder pump.
The manufacturing process in this facility primarily involves metal tooling and grinding, which in turn result in a lot of metal shavings.
If you are replacing a chronically failing pump or selecting a pump for a new application, a crucial tool in helping you choose and size a submersible pump is the submersible pump system curve. Developing a curve for your desired performance helps you determine if a pump will be right for your application. In this post, we’ll show you how to create a pump system curve.
