Before answering this question, We’d like to say that both of these pumps are the best in the business. In fact, both of them are known for high-quality performance and durability.

But, if you’re someone who’s new into this and want to select a better pump for you, there are some things you need to know.

AR Pump VS Cat Pump

First of all, there are certain factors that one pump performs better than the other. Well, you’re in luck as we’ve compiled everything about these two pumps in this article.

Moreover, we’ve even tried to bring out their best features and some cons. These factors will help you distinguish both of them. In the end, we’ve also given our opinion on this matter.

So, without further ado, let’s get right into it.

Features OF AR Pump

The ar pump or Annovi Reverberi pump works well on a gas engine pressure washer. This pressure washer pump also has a hollow connection system. As a result, it can mount on the engine shaft using this system.

Besides, the seal system of the pump ensures that the pump has both high and low-pressure seals in it. There are tons of other features that make this pump stand out. So, let’s take a look:

1. Standard Configuration

The configuration is simple yet maintains a good standard. The AR pump has a connection that can accommodate 7/8” diameter shaft gas engines. The convenient connection is established due to the mounting flange of the pump.

2. Built-in Pressure Valve & Injection System

The ar pump has a pressure valve inside of it. This was provided by the manufacturers and you can control the pressure of the pump with it. Hence, it’s easy to control the pressure using this valve.

On the other hand, there is also an injection system that is built-in inside the pump. But, you may ask what the injection system is.

Well, the system is a downward chemical injection system. And with this system, the chemicals flow downward for cleaning.

3. Pressure Seals

There are two types of pressure seals in the ar pump. One of them is high-pressure and the other is a low-pressure seal.

These seals make sure that no leakage is forming inside or outside the pump. At times, water or oil leaks in the pump which makes the pressure washer pump oil milky. So, it’s essential that no leakage forms in it.

4. Other Features

You thought we’re finished with the features, didn’t you? But, there are other features that you should know. Let’s take a look at them:

  • Cleaning units can couple to various motors due to the 3-piston alternating pumps.
  • Different connections of delivery are available.
  • It has a detergent suction system.
  • The body of the integral valve is made of aluminum. And the alloy pistons are driven by a mechanism of the swashplate.
  • 2 bearing systems support the pistons and pump shaft.
  • The pistons are hardened in a double gasket sealing system. The system also contains the steel pump head.
  • The intake valve is fitted on top of the pistons. As a result, this gives great efficiency.

Features OF CAT Pump

Cat pumps are the best when it comes to high-quality and performance. In fact, this industrial pump has been around for more than 40 years. Throughout these years, people have loved it for its durability and reliability. So, let’s look at some features of this pump:

1. Smooth Flow of Liquid

The design of the pump ensures that it has a smooth flow of liquid. The pump has a plunger design that makes the liquid flow pleasant. Also, the pump has a polished and durable surface.

But, don’t worry, the cat pumps have extended life for the seals and they never wear out. So, how do they have long-lasting seals?

The seal life is great due to the polished ceramic plungers of the pump. Not only do these plungers provide extended seal life but they also provide a solid wear surface.

3. Easy Flange Mounts

Yes, you heard me right, the compact flange mounts get permitted easily in the cat pumps. This is a great advantage that puts it ahead of its competitors.

In case you didn’t know what flange mounts do. Well, they mount directly towards gas engines. Having an easy permit of the flange mount means that cat pumps direct to most engines.

4. Fixed Chemical Injection System

The built-in chemical injection system is fixed in the cat pump. As a result, it provides a flexible cleaning experience.

5. Easy Installation

Worried about the installation of a gas engine? Well, you shouldn’t worry about this pump as it comes with easy installation.

Moreover, the pump is designed in such a way that it’ll bolt in the gas engine drive directly. As a result, you won’t have to face many problems in the installation process.

6. Other Features

There are some more features that you should know. They are:

  • It has excellent suction capability due to the inlet valves and ceramic plungers.
  • You don’t need any pulley or gearbox as the pump directly mounts to the gas engines.
  • The unloader mounts to other pumps and this ensures the pressure and pump control.
  • Multiple porting is available.
