A Compact Pump for Gas Powered Pressure Washers

The Centurion P1 is designed and built for efficiency and simplicity. It's got a direct axial cam design that lets it connect right to small or mid-sized gas engines with no belts or pulleys. Running at 3,400 RPM, it delivers smooth, consistent water pressure - no noise, no vibration, no fuss.

This little pump can handle just about anything - 3,000 PSI is no joke, and a 2.2 GPM flow rate delivers a nice steady stream of power. It's tough enough for heavy duty cleaning, but gentle enough for washing cars or detailing siding.

Perfect for:

• Gas-powered pressure washer replacement parts

• Compact mobile wash systems

• Light industrial cleaning

• Equipment maintenance

• Vehicle washing and detailing

• Patio, deck and siding cleaning

Built to Last

CP's engineering expertise really shines in the build quality of the P1. Components are chosen for their maximum lifespan under tough conditions.

• Tempered Steel Plungers: super tough and resistant to corrosion - thousands of cycles without a hitch

• Aluminum Manifold: light and durable - won't crack under high pressure

• Built-In Unloader: makes setup and maintenance easy

• Fixed Soap Injector: integrates chemical injection for easy transitions between wash and rinse cycles

• Thermal Relief Valve (85.300.022): protects the pump from thermal damage when you're not using it

Reliable and Easy to Maintain

The Centurion P1 is a workhorse designed for maximum reliability with minimum maintenance. It's got a sealed crankcase for clean, long-lasting lubrication, and only needs 2.2 fl oz of 30W non-detergent oil. The axial cam design means fewer moving parts, which means less wear and tear, and easier maintenance.

• Factory pre-lubricated crankcase

• Simple oil change process

• Standard thermal relief valve protection

• Seal and valve kits available for easy rebuilds

Built-In Unloader

Unlike other unloaders that require quite a bit of setup and extra plumbing, the built-in unloader on the P1 pump has automatic pressure regulation and a super compact form factor. This integrated design really simplifies the system and reduces potential leak points, so you can count on consistent performance and a lower risk of accidents.

When you let go of the trigger on your spray gun the built-in unloader redirects the water flow to reduce system pressure, which in turn extends the life of the internal seals and valves. The end result is super smooth and responsive performance and easy operation - even new users will get the hang of it.

Axial Pump Design: Efficient and Long Proven Track Record

The axial cam system is the most widely used pump style for compact, portable pressure washers - and for good reason. It's not only efficient, but it's also durable and designed to deliver steady, reliable pressure with as little mechanical complexity as possible.

In the Centurion P1, the axial pistons work together in perfect sync with the drive cam, which is essential for optimal balance and consistent output at high RPM. This results in a more compact, lightweight pump with fewer parts that are likely to wear out over time.

Benefits of the P1’s Axial Design:

• Super smooth and quiet operation

• A compact, lightweight build that makes it easy to move around

• Minimal vibration

• Easy to set up

• Lower maintenance than triplex pumps

Now, triplex pumps are ideal for high-duty, industrial systems, but axial pumps like the P1 are the go-to solution for portable and mid-range gas powered pressure washers that require a solid, lasting performance in a smaller package.

Lightweight, Portable and Built to be Moved Around

At a mere 7.3 pounds, the Centurion P1 is designed to be portable. Its direct drive configuration eliminates some of the extra components, which not only reduces the weight but also increases the mechanical efficiency. This makes it perfect for portable pressure washer units where space and weight are at a premium.

Despite its size, this pump delivers top-grade reliability and can handle long cleaning sessions without overheating or losing pressure. Whether you're using it for residential maintenance or daily commercial work the P1 maintains consistent performance even under variable loads and temperatures.

Designed with Real-World Use in Mind

Every single detail of the Centurion P1 has been optimized for practicality in the field:

• A 3/4 inch GHF inlet for easy garden hose connection. Just connect and go.

• A M22 Discharge Fitting for universal gun and hose compatibility. This means you can use any accessories you like without any hassle.

• A Fixed Soap Injector for consistent chemical draw. The P1 is designed to handle soap and water perfectly.

• A max inlet temperature of 43°C / 110°F for safe and stable operation with typical water supply temperatures. This is standard for the kind of water you're likely to be using.

• A 3,400 RPM operation that's perfectly matched to small and mid-range gas engines. This means you can trust that the P1 will work seamlessly with your motor.

Whether you're cleaning a fleet of work vehicles, maintaining farm equipment or restoring outdoor surfaces the P1 delivers steady, dependable pressure you can rely on.

Giving You Super Protection from Heat and Pressure

Continuous operation generates heat - and heat is the one thing that can really shorten the lifespan of a pump. That's why the Centurion P1 comes with a Thermal Relief Valve (85.300.022) that automatically releases hot water from the pump head when the temperature gets too high.

This simple yet essential feature prevents seal damage and extends the lifespan of the pump, especially during those times when you're letting the trigger go for a while and the pump is just idling along. And when you combine it with the built-in unloader, the thermal relief valve ensures balanced internal pressure and temperature so you get consistent performance in every environment.

Installation and Compatibility

Installing the P1 is a breeze, it's quick and easy to follow. It's designed for 7/8 inch horizontal shaft gas engines and it mounts right on to most standard small engine configurations - including popular models from Honda, Powerease, Kohler and LCT.

Installation Steps:

1. Mount the pump securely to the engine flange.

2. Make sure the 7/8" shaft and keyway are properly aligned before tightening.

3. Attach the 3/4 inch GHF inlet and M22 outlet hoses.

4. Fill with 30W non-detergent oil (2.2 fl oz).

5. Test the system for leaks and check the unloader is operating correctly.

This plug-and-play simplicity makes the Centurion P1 an excellent choice for pressure washer rebuilds, replacements or custom equipment designs.

Tips for Long Maintenance for a Long Life

To ensure your Centurion P1 delivers years of reliable service simply follow these simple maintenance steps:

• Check the oil levels before every use and replace them every three months or 100 operating hours.* Keep an eye on the inlet screen for any debris that might be causing cavitation - and clear it out regularly to avoid problems.

• Give the chemical injector a good flush after each time you use it to prevent clogging and get the most out of it.

• Run clean water through the pump before you put it away to get rid of any detergent residue that might be lingering inside.

• Store your pump somewhere dry and frost-free, where it can't get damaged by moisture or extreme temperatures.

Regular maintenance is key to keeping your pump running at full pressure and flow, far beyond what you'd get from a lower-quality pump.
