The High Costs You Can Incur from a Failing Slurry Pump

failing slurry pump

In just about any industry that involves heavy machinery and expensive equipment, it’s all too easy to adopt an if-it-isn’t-broken-don’t-fix-it approach. Waiting until your slurry pump is failing to address problems might feel intuitive and may seem like the most cost-effective method, but—in reality—you’re costing yourself a lot more in time and money. 

Keep reading to learn more about the potential costs you could incur from a failing slurry pump. 

So, You Have a Failing Slurry Pump—But What’s Really Going On?

In this section, we’ll take a closer look at some of the most common slurry pump malfunctions, as well as what they’ll mean for your production process. 


When there’s insufficient NPSH, you run into pump cavitation. Pump cavitation can have a nasty effect on some of the most crucial parts of your slurry pump, including the pump seals, pump casing, and the impeller. The longer you put off addressing pump cavitation, the more likely it is that you’ll have to shell out a lot of money to replace these parts. 

Air Entrainment

The term “air entrainment” refers to any condition that involves your slurry pump pumping liquid that already contains gas. Typically, turbulence in the suction lines is what causes these kinds of conditions, and the turbulence is usually due to improper setup. 

One of the simplest ways to solve this problem—and avoid serious damage to your pump’s impeller—is to use a straight run of pipe on the suction side. This will help minimize turbulence and deliver a more uniform flow. 

Discharge Recirculation

When a slurry pump’s operation is below the recommended BEP, discharge recirculation can occur. This condition refers to large amounts of design flow not properly being pushed out of the discharge. This allows a lot of abrasive slurry to recirculate within the casing. This leads to damage, air pockets (which can lead to cavitation) and serious wear to important pump components. 


Unfortunately, clogs come with the territory—but they don’t always have to. Clogs occur when a slurry pump encounters a bigger solid than what they’re designed to handle. The best way to avoid clogs is to make sure you’re very familiar with what you’re pumping, your slurry pump, and what it’s designed to handle.
