If the liquid you’re pumping contains solids, there are a number of solids handling submersible pumps that might be appropriate for your application. To avoid clogs or burning your motor out, you need to make sure you have the right pump. There are key questions that help determine which pump will solve your problems. In this post, we’ll examine these questions so that you’re prepared when you talk with your provider.1. What Type of Solids Are You’re Pumping?
Understanding the solids in your liquid helps your provider determine the right type of pump for your application. We’re focusing on wastewater, so we can assume your solids are not abrasive (abrasive solids would require a hard metal, agitator pump). Most likely, they are large and soft or long and stringy.
In a single shift at a food and beverage processing plant, the quantity and variety of solid waste managed are daunting. Animal processing pushes bones, sinewy tissue, and other offal into the pit. Processing fruits and vegetables leaves hard rinds, shells and skins to flow into floor drains and waste collection areas. Accidental waste, such as sticks, wrappers, bags or cans also fall into the mix. Caustic or hot fluids from required washdown add a corrosive component. All these materials must be reduced to a state where they will flow freely into the next step of neutralization and pre-treatment for disposal.
The materials from floor drains require a pump with the ability to shred the solids and still move the fluids.
