Centurion TK4 120° Forward-Facing Tank Head Cleaner, 1/2" Inlet, 5 to 16 GPM, 3,600 PSI, 212°F, Built to Order

A Real Game-Changer for Industrial Tank Cleaning: Cleaning Heads That Deliver

The Centurion TK4 is a pretty rugged, rotating tank cleaning head built to handle a range of industrial cleaning challenges, blasting through tough interior cleaning jobs on industrial tanks, totes, IBCs, small tanks, and larger process vessels. Forget hours of tedious manual scrubbing or dawdling over slow-drip rinsing from static spray balls. The TK4 gives you high-impact jets in a controlled 360-degree pattern that wipes out sludge, scale, and product gunk from every surface inside the tank. And to top it off, the TK4 is a self-propelled, water-driven system – no external motors, no electrical connections inside the vessel to worry about. It's designed to be used in conjunction with Barens Centurion pump systems, so you get a complete tank-cleaning solution right out of the box, with a full range of tank-cleaning options.

Why You'll Love the Centurion TK4

Every single feature on the TK4 is designed to solve a real problem that's been eating up your time, wasting water, or putting your workers at risk during cleaning.

• Cleaning cycle times are down to minutes, not hours – The TK4's controlled rotation pattern and powerful jets can get the job done on medium-sized tanks and common IBCs in a single automated cycle. Other rotary jet tank cleaning devices, like the Orbitor Eco, can crank out cleaning cycles in under 10 minutes, and the TK4's in the same ballpark – replacing manual wand work that can take an hour or more per tank.

• You'll use less water and detergent per clean; the TK4 uses focused impingement jets that deliver cleaning fluid exactly where it's needed. Static spray balls require a lot more liquid for effective cleaning because they just wet surfaces without actually delivering any real mechanical force. Tank cleaning nozzles like the TK4 help with reducing water and chemical consumption by 30–70% compared to static systems – that's a lot of your hard-earned cash saved.

• Worker safety gets a big boost – Automated operation means you're minimizing the risks associated with confined space entry during cleaning. Less time inside tanks means less exposure to residues, chemicals, and hazardous environments. The TK4 does the scrubbing for you, so your crew can stay outside the vessel where it's safe.

• You'll get complete coverage, every time – The TK4's got a controlled rotation system for consistent jet streams across two axes. Every square inch of tank wall, roof, and bottom head gets hit, with reliable performance across different tank sizes. No more worrying about whether a section got cleaned – the TK4 makes sure it does.

• It can take a beating – Built from 316 stainless steel (housings and internals) the TK4 can handle aggressive chemical detergents and extreme thermal conditions. Tank cleaning nozzles commonly use austenitic stainless steels like AISI 316L for corrosion resistance. The internal turbine and gear reducer are optimized for mechanical efficiency without external power, and a built-in inlet strainer protects internal components from debris.

• Installation and maintenance are a breeze – The TK4 connects through a ½-inch stainless steel inlet, fits through standard manways, and requires no wiring. One technician can handle installation and removal between tanks – no problem.

What Sets the TK4 Rotating Cleaning Nozzles Apart from Your Ordinary Tank Heads

Most tank cleaning equipment falls into one of two categories – cheap static spray balls that flood the tank with liquid but deliver almost no mechanical impact, or rotating cleaning nozzles that spin fast but wear out in weeks. The TK4 is neither, with a lower-wear, compact design that holds up better in real-world cleaning service.

• Built to take the pressure – The device withstands high pressures up to 3,600 PSI and flow rates of 5 to 16 GPM. High-pressure cleaning nozzles operate at pressures way higher than that – the TK4 runs well above the threshold, delivering the kind of impact needed to dislodge dried product, biofilm, and baked-on residue from the tank wall.

• True 360-degree coverage – Rotating nozzles provide 360-degree coverage for efficient cleaning. The TK4 uses controlled rotation rather than the reaction-force spinning that causes cheaper rotating heads to skip and chatter. The result is overlapping jet paths with consistent dwell time across every surface, rather than a weak mist pattern that leaves contaminants behind.

• Adjustable nozzle coverage – It's got nozzle patterns ranging from 20° to 120° for optimized cleaning coverage. The 20° setting concentrates jets for maximum reach into large tanks and hard-to-reach areas. The 120° setting broadens the spray head pattern for faster coverage in smaller vessels and containers. You pick the configuration based on tank diameter and residue type.

• Lower lifetime ownership costs – Corrosion-resistant 316 SS internals, an integral inlet filter, and replaceable seals and nozzles mean the TK4 keeps running where cheaper spinning balls need to be replaced every few months. Specialized applications might use superalloys such as Hastelloy, but for most industrial and food-processing work, 316 SS is the standard for durability.

• Compact and Mighty - Cleaning Large Tanks with Ease – The compact design makes it easy to pass through standard manways and bung openings, while still putting real cleaning force where it counts. That makes the TK4 suitable for large vessels such as process tanks, IBCs, and bulk storage, while still handling tough jobs in wash bays, CIP loops, and field cleaning rigs that matter to operators.

How the Fluid Driven Centurion TK4 Tank Head Cleaner Works Its Magic

Water comes in under pressure, drives a turbine and gear mechanism inside the TK4, and then shoots out as super-powerful jets through precision nozzles. A clever gear reducer makes sure the rotation speed stays just right, washing the tank interior in a repeating pattern of overlap. And don't worry, you don't need any electricity or compressed air - just the energy of the cleaning fluid itself gets the job done.

Step-by-Step Operation for the TK4

1. Get Connected to Your Centurion Pump System – First, attach the TK4 to a Barens Centurion pump using a high-pressure hose and a ½-inch stainless steel inlet fitting. Then insert the head through the tank manway, wash port, or top access hatch, and ensure it is as centered as possible inside the vessel.

2. Start the Flow and Let it Go – When you turn on the pump and reach operating pressure, the pressurized water drives the TK4's internal turbine, which starts to rotate on two axes, sweeping solid jets across the tank's roof, walls, and floor.

3. Let the Cleaning Pattern Do the Work – Over the course of the cleaning cycle, the jet pattern repeats, overlapping, breaking down, and rinsing away scale, sludge, product residues, and contaminants. How long the cycle takes depends on the tank size and how dirty it is: a light rinse of an IBC might take a few minutes; a heavier clean of a process vessel takes longer.

4. Rinse and Take a Look – After the timed cycle, shut off the flow, pull the TK4 out, and visually inspect the tank interior. If you need to, run a final rinse cycle to get rid of any material that's been loosened but not yet cleared from the drain.

5. Move on to the Next Tank – The TK4 doesn't need any downtime; you can just disconnect, reposition, and get cleaning the next tank. In a wash bay operation or CIP loop, this keeps turnaround times short.

Product Details: Centurion TK4 Tank Cleaning Equipment Specifications

Some quick-reference specs for those who need them:

• Maximum operating pressure: 3,600 PSI (248 bar), which is more than enough to handle tough jobs involving product buildup and grease.

• Maximum inlet temperature: 212°F (100°C), making it ideal for hot-water washes and clean-in-place cycles with all sorts of heated detergent solutions.

• Nozzle coverage angles - You can set them to 20° or 120°, depending on the tank diameter, distance to the wall, and the type of cleaning you are doing.

• Materials of construction - The body and internal components are all 316 stainless steel, and that's just the beginning; the TK4 is designed to be used with all standard industrial chemicals and, where needed, food-grade materials.

• Connection type: A ½-inch stainless steel inlet and standard high-pressure fittings all the way, just like the Barens Centurion pumps.

• Drive mechanism - All internal and powered by the fluid flow itself - no external motors or power needs.

• Inlet protection - A built-in mesh strainer that keeps all the nasty stuff out of the internal gears and nozzle orifices.

• Weight and dimensions - Small and lightweight enough for a single person to handle, transport, and insert through standard manways.

• What Comes in the Box - The tank head cleaner assembly, the standard inlet fitting, and all the user and maintenance documentation you'll need.

Who the Centurion TK4 Tank Head Cleaner is For

The TK4 is perfect for anyone who needs to clean tanks on a regular schedule and wants reliable results without having to get a team into a confined space.

• Facilities and fleet managers - You guys are always on top of wash bay operations for refuse trucks, delivery fleets, and all the pipes and machinery with interior tanks that get clogged with buildup, slowing turnaround. The TK4's automated cycle and rotating nozzles really do help - and it's easy to get to all the tanks in the wash bay without needing extra help.

• Agricultural and Ranch Operations - Farms that need to quickly clean spray rigs, nurse tanks, fertilizer and chemical tanks, and livestock watering systems will find the TK4 up to the task. It can handle the chemicals and liquid residues common in agricultural equipment without breaking down or clogging, making it a dependable choice for harsh environments with demanding wash conditions.

• Small Industrial and Processing Plants - Plants running process vessels, fermenters, and CIP loops that need regular cleaning of residue, scale, oils or product buildup will appreciate the TK4's complete coverage & hot water capability. It's also a strong fit for the food industry, where hygienic tank cleaning helps support consistent product quality.

If you're already using a Barens Centurion pump and want to clean tank interiors in half the time, the TK4 is a direct upgrade from manual labor & static spray balls.

How to Choose, Install & Set Up Your TK4

The success of the TK4 depends on pairing it with the right pump, hose and controls - or it just won't deliver.

Choosing the Right Configuration

• Match flow and pressure to the TK4's operating range: the TK4, a rotary nozzle, requires a pump capable of delivering 5-16 GPM at up to 3600 PSI. Don't even think about running it on anything less than 5 GPM - it'll stall, or if you try to push it too high, you'll blow the rated flow.

• Pick a nozzle angle based on tank size & residue type - If your tank is big & the head is far from the walls, the 20° nozzle is your best bet for getting the job done over a longer distance and for longer throw applications. For smaller tanks where speed matters more than reach, go with the 120° nozzle, which is better for compact vessel interiors, & get it over with. If you're dealing with sludge or dried-up product, higher pressure & longer cycle times are the way to go; for routine rinsing, shorter cycles at moderate pressure will do.

• Choose a compatible detergent - Standard pressure washer detergents approved for use with stainless steel equipment are okay, but don't try anything too crazy (strong acids, caustics) without checking in with Barens first.

Installation & Setup Basics

1. Pop the TK4 into the tank - Stick it through an existing manway, wash port or top access hatch. Try to center it as best you can to get even coverage across the entire tank diameter. If your tank has an offset access, you may need to adjust the nozzle angle a bit.

2. Connect it to the high-pressure line - Hook up the TK4 to your Centurion pump using a high-pressure hose and fittings rated for 3600 PSI. Every single thing in that line (hose, couplings, fittings) has to be good for this amount of pressure or it's a recipe for disaster.

3. Make sure the water supply & filtration are up to snuff - Don't skimp on the supply hose & inlet filter. If the water flow is restricted or air gets trapped in the line, it'll cause the pump to cavitate & damage the TK4's internal turbine. The built-in strainer on the TK4 is a nice safety net, but primary filtration should happen upstream.

4. Set the pressure & cycle time - Run the pump at a pressure that makes sense for the type of residue you're dealing with. Don't be a stranger to standardizing cycle times - a few minutes for light rinsing, longer for heavy stuff.

5. Run an initial test and inspect - Test it out with clean water first. Give it a good eyeball to make sure there aren't any leaks around the swivel & inlet, check that the head turns smoothly in both directions, and verify that you're getting full coverage on the tank walls. If any part of the tank still appears incomplete, you might need to adjust the positioning or nozzle angle a bit.

Keeping Your TK4 Tank Head Cleaner Running

Maintain your TK4 the right way, and it'll be your best friend for years to come. Blow it off, and you'll be stuck with nozzle wear & seal failure in no time.

Routine Maintenance

• Give it a once-over before every use - Check for leaks at the swivel joint & inlet fitting, and give the head a gentle spin by hand to make sure it's turning freely. If there's something visually amiss with the nozzles, you should probably swap 'em out.

• Keep the feed water clean - Clean or replace the pump's inlet strainer & the TK4's built-in mesh filter on the reg. Don't let this stuff build up in the water & ruin your TK4's internal workings.

• Check nozzles & jets periodically - They will wear out over time, and if you're working with nasty stuff, it'll happen faster. Replace them if the orifice diameter gets out of whack.

• Service the seals & bearings on a regular basis - They will eventually need it, so mark it down in your maintenance calendar. Replace them alongside your Centurion pump's maintenance schedule - or your operation will come to a screeching halt. Finally, a spare seal kit or two on hand won't go amiss.### Storage and Off-Season Care for Your TK4

• Flush after every chemical use, please - After running detergent or sanitizer through the system, give the TK4 and all lines a good flushing with clean water. You see, leaving residual chemicals hanging out in contact with seals and internal surfaces is a recipe for disaster - it basically accelerates corrosion and degradation.

• Keep the TK4 from freezing up - If you live in a cold area, make sure to circulate some pump saver or antifreeze solution through the pump and TK4 before shutting down for the season. Water that gets trapped in the internal passages will freeze, expand, and crack the components, which is exactly what you want to avoid.

• Store the TK4 in a dry, frost-free space - Try to keep the TK4 indoors, away from the dirt, moisture, and accidental impact that's just waiting to happen. And if it's mounted on a lance or rig that's stored outside, make sure you cover it up and give it a good once-over to make sure it's been fully drained.

Some Common Questions We Get Asked

Is the Centurion TK4 tank head cleaner pretty easy to use? Yeah, it is. Just connect it to a Centurion pump, stick it in the tank, and hit start. The internal turbine will take care of the rest. You can probably get up to speed in under 15 minutes.

What kinds of tank sizes can I use the TK4 on? The TK4 is a good fit for small tanks, medium-sized tanks, and larger vessels within its operating range, from IBCs and totes upward. We've got bigger rotary jet systems that can handle tanks up to 100ft in diameter, but the TK4 is sized for the smaller end of that range. If you've got a very large tank, you may need a bigger head from our range or multiple insertion points.

Do I need a Centurion pump to run it? To get the most out of the TK4, we recommend using a Centurion pump from us, plus we've got integrated support for our customers who use them together. Any pump that delivers 5-16 GPM at up to 3600 PSI should be able to power the TK4, but the Centurion pumps make it a whole lot easier.

Can I use hot water and detergents with it? The TK4 can handle inlet temperatures up to 212 degrees F and works with standard pressure washer detergents. The right material selection can help prevent contamination in hygienic applications. But if you're thinking of using more aggressive chemistry or higher concentrations, give us a holler, and we'll confirm that it's safe for the seals and materials.

How often should I be servicing the TK4? If you're using the TK4 daily, you should probably check the nozzles and seals every few weeks. In terms of seal and wear-part replacement, plan to do it based on the number of operating hours and the quality of the water - it's similar to the maintenance cycles for the pump. And of course, using clean water and good filtration helps extend its lifespan.

What happens if you run it dry? Running the TK4 without water or a starved inlet will cause it to overheat and damage the internal seals, gears, and turbine components. This is the same risk for any high-pressure pump. So always make sure there's a steady supply of water before starting the system.

Where can I get spare parts and support? We've got spare nozzles, seal kits, and technical support available directly from us for TK4 users.
