In most submersible pump applications, bad things happen when a pump fails. What may start with standing in a growing puddle of water, sewage, chemicals or other industrial waste leads to a domino effect on the entire production. This can lead to unscheduled downtime for an indeterminate amount of time or even an environmental fine for waste discharge. As a result, your first instinct is to call your pump supplier for the fastest replacement pump they can get you. This is the time when a submersible pump solutions partner makes all the difference. Here’s why.Getting the Right Pump Fast
A submersible pump solutions partner understands that short lead times aren’t enough. You need the right pump fast. To that end, a quick phone conversation can make a huge difference.
Especially if you’re dealing with a rugged application, you have questions about submersible pumps. We receive a lot of common questions that we’ll begin to address here. We hope that by sharing them with readers, we can make your selection process faster and easier. We’ll also clarifying some issues you may not have thought to ask. We’ll include additional FAQs in future posts.How many starts per hour can a submersible pump handle? Can a cast-iron pump handle more than a stainless steel pump?
Before we delve too deeply into this question, let’s first define what “starts per hour” means. It’s the number of times in an hour that a pump starts pumping and then stops. It’s also known as the “duty cycle”. Both stainless steel and cast-iron BJM pumps are rated for ten starts per hour or fewer.
Safety is a chief concern for all industries. Certain industrial companies in specific markets (Ex. oil & gas, mining, etc.) have regulations related to combustibility due to gases produced or that are existing with applications. In these cases, submersible pumps specially constructed to eliminate the risk of explosions are necessary. In fact, many local jurisdictions explicitly mandate the use of explosion proof pumps.Higher Risk Applications
Certain applications are especially susceptible to explosion risks. The mining and oil & gas industries face pressurized, escaping underground gas. In chemical plants and refineries, liquids emit flammable vapors. Landfill leachate applications include methane from decomposing waste. Also, power plants and industrial plants may have volatile chemicals present. In these cases, a spark from a pump or even a hot enough surface can ignite the gases or chemicals.
