Built for the Toughest Jobs
The Centurion P10 is built to perform at the highest level for as long as possible. It's designed to handle the kind of heavy-duty use that will make other pumps quit on you. Whether it's construction, agriculture, manufacturing, or fleet maintenance - this pump can handle it.
8.5 gallons per minute of water flow means you can cover a lot of ground fast, making it perfect for using with multi-gun systems and surface cleaners. And with 4,100 PSI - get ready to blast away even the toughest grime and grunge.
The Triplex Ceramic Plunger System
At the heart of the P10 is Centurion's triplex plunger system - the real secret to its success. With three precision-ground ceramic plungers, this pump delivers smooth, consistent and pulsation free water delivery. It's the mark of a pump that's built to last.
Ceramic plungers are the way to go for heavy-duty work because they can withstand the heat and grime of long, hard use. Steel plungers just can't compete - they wear out fast.
The Belt Drive Advantage
The belt-drive system is a game-changer. By connecting the engine or motor to the pump via a pulley and belt - you get a lower RPM, which means less vibration, less heat and less maintenance. And with the belt system acting as a shock absorber - your pump will last a lot longer.
Serious Power for Serious Cleaning Jobs
The Centurion P10 delivers 8.5 GPM at 4,100 PSI - a perfect balance of flow and pressure for the toughest industrial cleaning jobs. You'll be able to clean faster and deeper with ease - taking on jobs that would normally be a challenge.

Faster rinsing and higher productivity - the P10’s impressive water volume really delivers. That means a critical advantage for contractors & industrial teams looking to squeeze more out of their time.
Brass Manifold: Built to Stand up to Pressure
The P10's brass manifold is solidly engineered to withstand both high pressure & high temp without losing its shape or getting corroded. It’s got superior mechanical strength & thermal stability so its performance stays rock solid even during continuous operation.
There’s a big difference between brass and composite or aluminum manifolds. Brass doesn’t lose its shape over time like some of those other materials can. That means fewer leaks & more stable flow across the pump’s entire lifespan. The precision-machined brass ports fit perfectly with inlet & discharge connections, reducing stress & making installation that much easier.
Adjustable External Unloader
The external unloader on the P10 gives you total control over your system pressure. You can adjust it to suit whatever cleaning job you’re working on - whether you’re stripping paint from metal or rinsing delicate surfaces. It’s all about flexibility.
The unloader works by diverting excess water back to the inlet, so you don’t have to worry about those damaging pressure spikes. Plus, because it’s external, you can easily get to it to adjust or replace it as needed - which is a real advantage in demanding environments where every minute counts.
Adjustable Chemical Injector
The P10’s adjustable soap injector lets you really fine-tune the amount of detergent or chemical you’re using, so you get the best cleaning results with the least amount of waste. Whether you’re applying degreasers, disinfectants or foaming cleaners, you can adjust the mixture to exactly what you need.
The system is built to be durable & corrosion-resistant, & it’s designed to keep sucking even at low pressures, so you can count on it to perform throughout its service life.
Thermal Relief Valve for Overheating Protection
When you’re running the pump in bypass mode - with the spray trigger released - water can get pretty hot inside the pump. That’s why the P10 comes with a thermal relief valve (85.300.022) that kicks in to release the hot water & bring in cooler water from the inlet. This keeps the operating temp safe & prevents overheating that can ruin the seals, plungers & valves.
This feature means you can run the pump in hot environments or leave it sitting idle for hours without worrying about damage.
Low RPM, High Output Efficiency
The P10 runs at 1,750 RPM - not super fast, but it gets the job done with way less stress on its internal components. This slower speed means:
-
Less vibration & noise
-
Cooler operating temps
-
Longer seal & bearing life
-
Smoother, more stable pressure output
This low RPM also makes the P10 super versatile - it’s compatible with both gas-powered engines & electric motors, so you can use it in all sorts of commercial & industrial systems.
Precision Lubrication & Cooling
The P10’s crankcase has a 37 fl oz oil capacity, so it’s got all the lubrication it needs to keep moving parts running smoothly under high load. And the 30W non-detergent oil really helps reduce wear & friction.
The forged crankshaft, oversized bearings & heat-treated connecting rods are all precision-engineered to work together in perfect sync under heavy loads. Routine oil checks & changes are a breeze, so your pump stays in top condition for thousands of hours.
Designed for Heavy-Duty Commercial Use
The P10 is built to thrive in the toughest environments out there. Its power, flow & endurance make it a perfect fit for:
-
Commercial & industrial wash bays
-
Fleet washing & maintenance
-
Agricultural & food processing equipment
-
Heavy machinery & construction cleaning
-
Surface preparation & restoration
-
Multi-gun cleaning setups
With its low-RPM belt drive, high-volume triplex design & rugged brass manifold, the P10 can keep going shift after shift in demanding conditions, delivering performance you can rely on.
Easy Maintenance & Serviceability
We design our pumps to be as easy to fix as possible, so you can get back to work fast. The P10’s layout lets you access all the key components in seconds - seals, valves, plungers & the crankcase are all easy to see & maintain.
The external unloader & oil fill port make servicing a breeze, & the pump’s components are built to last - you won’t need to do much maintenance over the years. When you do need to rebuild, Centurion’s kits are widely available & a snap to install.
