Hey guys, it’s Jake here from the Tank with Mixer crew, and if you’re reading this, chances are you’ve got a tank that’s… well, just not cutting it anymore. Maybe it’s mixing your industrial batch too slow, leaving sediment stuck at the bottom, or you’re just sick of dealing with inconsistent results that cost you time and money. Upgrading your tank with a mixer isn’t as scary as it sounds—trust me, we’ve helped hundreds of folks do this over the years, and today I’m breaking down exactly how to pull it off like a pro (plus a few tips only we mixer nerds know). Tank with Mixer
First off, let’s get one thing straight: this isn’t a “buy the shiniest mixer you can find and bolt it on” kind of project. We’ve seen way too many people waste cash on the wrong gear because they skipped the step of figuring out what their tank actually needs. Let’s start with the basics—what’s your tank even for? Are you mixing food-grade sauces, chemicals that eat through regular metal, or maybe wastewater with chunky solids? That’s gonna dictate every single choice you make next.
First step: Do a quick audit of your existing setup. Pull up the specs for your tank—how big is it? Diameter, height, total volume, and wait, what’s the working volume (the actual amount you fill it with, not the max)? A lot of people forget that overfilling or underfilling throws off mixer performance. Then check your current tank’s internals: is there a baffle? Baffles are those little metal plates on the side that stop the liquid from just spinning in a circle (spin = bad, mixing = good). If your tank doesn’t have baffles, that’s a big red flag—your old mixer’s probably wasted half its power just swirling air around. Also, check the bottom of your tank: is it flat, conical, or dished? Conical bottoms are great for getting rid of sediment, but they make mixer placement trickier.
Next up, the mixer itself—this is the fun part, but also the make-or-break part. Let’s talk types, because not all mixers are created equal. We mostly deal with three common styles, and picking the wrong one is like using a spoon to dig a hole. First, there’s top-entry mixers—these are the most common, perfect for tanks that are easy to get to from above (like a storage tank in a warehouse). They mount right on the top flange, and the shaft goes down into the liquid. Second, side-entry mixers—great for big, tall tanks where climbing on top is a hassle, or if you need to save floor space. They bolt on the side, shoot the liquid at an angle to get circulation going. Third, bottom-entry mixers—these mount on the bottom of the tank, which is awesome for getting every last bit of sediment moving, since they’re right at the source. We used to steer clear of bottom-entry for food-grade stuff, but modern sealed motors make that totally safe now.
Wait, you can’t just pick a type and go—you also need to get the mixer size and power right. This is where a lot of DIYers mess up. If your tank has sediment at the bottom, a mixer that’s too small will just spin the top layer and leave the gunk there. If it’s too big, you’re wasting energy (and cash on electricity every month). The rule of thumb we use here is based on the “impeller tip speed”—that’s how fast the blades are moving at their edge. For most general mixing, that’s around 5 to 8 feet per second, but if you’re dealing with thick fluids (like sludge or syrup), you might need to bump that up to 10 or even 12 ft/s. For thin stuff like water, you can get away with a lower tip speed. Also, power isn’t just about the number on the motor—look for “hydraulic horsepower” vs. “brake horsepower.” Brake horsepower is the total power going into the motor, but hydraulic is the power actually making the liquid move. We always recommend going with a mixer that has a good efficiency rating—over time, a slightly more expensive efficient mixer will save you way more on electric bills than you think.
Now, installation—this is where a lot of people try to cut corners, and it bites them in the ass. First, if you’re retrofitting an old tank, you might need to modify it to fit the mixer. For top-entry mixers, you’ll need a flange on the top of the tank (we can custom-make flanges for your tank if you don’t have one—no need to buy a whole new tank). For side-entry, you’ll need to cut a hole in the side, but here’s a pro tip: don’t just cut a random hole. The standard height to mount a side-entry mixer is about 1/3 of the way up the tank from the bottom. That way, the flow from the mixer hits the bottom, pushing sediment up, and circulates all the way around. If you mount it too high, all you’ll do is swirl the top liquid and leave a dead zone at the bottom. Also, for bottom-entry, make sure you have a cleanout port or easy access to seal it later—you don’t want to have to drain the whole tank every time you need to service the mixer.
Wait, what about the impeller? That’s the part actually doing the mixing, not the motor. Common impeller types: propellers are great for thin fluids, they move a lot of liquid fast. Turbines are better for thicker stuff or when you need more shear (like if you’re mixing powders into liquid). Paddle impellers are simple, cheap, and good for gentle mixing (like food products where you don’t want to break anything). Again, this ties back to your fluid: if you’re mixing a powder that likes to clump, a turbine impeller with high shear will break those clumps apart way better than a prop. We’ve had customers try to use a prop for mixing cement slurry, and they wonder why it’s still lumpy—turns out, they picked the wrong impeller.
Once you’ve got the mixer mounted, you’re not done yet—you have to test it, and I mean actually test it, not just turn it on and call it a day. Run it for a full cycle, then check a few things. First, look for air entrainment—you’ll see bubbles if the mixer is spinning too fast or positioned wrong. Bubbles are bad because they reduce mixing efficiency and can contaminate food-grade products. If you see bubbles, adjust the depth of the mixer shaft or slow the speed down a little. Next, check for dead zones—use a stick or a flow meter (or even just pour some dye in, that’s a cheap trick) to see if there’s any spot in the tank that the liquid isn’t reaching. If there’s a dead zone near the bottom, you might need to adjust the mixer angle or add an extra baffle. Also, pay attention to noise and vibration—if the mixer is shaking the tank like it’s going to fall apart, that’s a sign it’s unbalanced or the impeller is the wrong size. That’s a quick fix, but better to catch it early than have the whole thing come loose.
Now, a few common mistakes we see all the time, so you can avoid them. First, don’t ignore maintenance. Even the best mixer needs to be serviced every 6 months—check the seals, tighten the bolts, lubricate the shaft. If you skip maintenance, you’ll end up with a leaky mixer or a broken motor way sooner than you should. We offer maintenance plans for all our mixer setups, so you don’t have to remember every little thing. Second, don’t try to retrofit a mixer that’s way too powerful for your tank. We had a customer last year who bought a 10 HP mixer for a 500-gallon tank—total overkill. It was so powerful it was splashing liquid all over the floor and wearing out the impeller in 3 months. He swapped it for a 2 HP unit, and it’s worked perfect ever since. Third, don’t forget about safety. If you’re working with hazardous materials, make sure your mixer has explosion-proof motors, and all the wiring is up to code. We build our mixers with safety standards front and center, so you don’t have to worry about that.
Wait, what if this all feels like too much? I get it—you’re busy running a business, not a mixer engineering lab. That’s why we offer custom upgrades. We can send someone out (or do a virtual audit if you’re not local) to look at your tank, figure out exactly what you need, and even handle the installation for you if you want. No guesswork, no wasted money, just a tank that mixes like it’s supposed to. For example, last month we had a biofuel producer whose old tank was leaving algae sediment that gunked up their lines. We swapped their old 3 HP top-entry mixer for a 5 HP bottom-entry turbine mixer, and now they’re reporting zero sediment buildup, less downtime, and lower electricity bills. That’s the win we love to see.
If you’re thinking about upgrading your tank with a mixer, my best advice is to not wait until something breaks. We see customers all the time who put it off until their production is half messed up, and then they’re scrambling to find a quick fix. A little planning now saves you a lot of headaches later. Start by writing down your tank specs, your fluid type, and what you’re actually struggling with (slow mixing? sediment? inconsistent batches?). Then hit us up to chat through it—we don’t push you to buy the most expensive thing, we just want to find what works for your needs and your budget.
At the end of the day, upgrading your tank with a mixer isn’t about buying a new toy—it’s about making your process smoother, saving you time and money, and giving you consistent results every single time. We’ve been in the tank and mixer game for years, and we’ve seen firsthand how a good mixer can turn a mediocre setup into a top-performing one.
