What We Like

Incredible kit

Himore pressure washer pump is ideal for most standard residential or commercial pressure washing jobs. Its incredible features are all-metal construction, thermal relief valve, and chemical injection port and come with hose barbs on the inlet tube, outlet tube, and unloaded.

Easy to install

This pump may require ½” spacers when installed, depending on the motor configuration. Spacers are used in the case that the pump arm(s) hits the engine or can’t reach the underside of the frame such as if the engine has a longer shaft. If spacers aren’t used when installing, the pump legs will break from stress.

Amazing HP

This pump mounts vertical and is a rear-facing engine that pumps up to 2800 PSI. The pump needs at least 5.5 HP to handle PSI levels this high.

What We Don’t

Average pump shaft

We were disappointed that the aluminum pump had completely disintegrated. The shafts that wound the pump just were not able to hold up to our lights and pressure washing equipment, so we put them through their paces.

If what they were made of was poor-quality metal then they would’ve been destroyed long ago, but unfortunately, they just tore in two!

Tester says about this Product

Easy to install on a 2700 PSI BlackMax with a Honda GCV160 engine. It fit right on with no modifications. As it is a brand new pump I let the water run a little longer than usual just to make sure that the pump was primed.

Started up and it worked great, fantastic actually. In about 5 minutes (or less) it locked up and even killed the motor. I got it cranked again but now it doesn’t build pressure. It sprays but just water hose pressure. No leaks anywhere.

I will check the unloader valve before I send this back. If that works I will update this review. Still not off to a good start. I will add that the shipping was fast.

Ordered on a Saturday and received on Wednesday with Memorial Day in between, standard free shipping. That part was awesome. Update 5/30/20: I checked the unloader valve per the instructions that came with it and it was fine but was pure heck getting back in. By PapPap

AR ANNOVI REVERBERI, 2400 PSI RMW22G24-EZ Triplex Standard Configuration

Best for Max Bar

AR ANNOVI REVERBERI RMW25G28-EZ-SX Triplex Plunger pressure washer Pump is one of the best in the industry and its quality is almost unmatched.

This machine comes with a 3-year warranty and is capable of producing a flow rate of 2.2 gallons per minute. It has a triplex plunger pump and balanced rotor and is also capable of producing a max pressure of 2400 PSI.

This is a very high pressure and will make any surface shine and can also be used on vehicles and RVs. If you are having trouble with your pressure washer, you might want to implement the use of a ‘plunger’ by connecting an unloader to the built-in brass unloader tip.

This helps relieve excess pressure caused by high-pressure water spraying furiously against certain surfaces and in turn, helps limit any potential damages or breakdowns.

ARANNOVI REVERBERI RMW25G28-EZ-SX Triplex Plunger Pressure Washer Pump has an amazing Thermal Relief Valve that helps to keep your unit from overheating. It disengages during normal operation to prevent the pump from getting too much hot water.

What We Like

Thermal Relief Valve

The thermal relief valve is standard in all Triplex models. It is a wax fixture that slowly shrinks when temperatures within your water pump increase.

Once the maximum temperature of 140 degrees Fahrenheit has been reached, this means the heat threshold has been breached, the valve will trigger and empty out the water.

The ARANNOVI REVERBERIs thermal relief valve helps keep your pump from overheating so that you may have a working pump for many years to come!

The amazing shaft connection system

AR ANNOVI REVERBERI, 2400 PSI RMW22G24-EZ Triplex Standard Configuration pump easily attaches directly to most standard size 7/8 inch OD vertical shaft gas engines that are found on many OEM and aftermarket utility carts.

Built-in accessories

This pump includes some incredible features like a built-in pressure control valve, a downstream chemical injection system, and an EZ start valve.

3-piston alternating volumetric pumps for use on cleaning units can be directly coupled to various types of motors. All these built-in accessories make this product different from others.

What We Don’t

Average quality

AR ANNOVI REVERBERI, 2400 PSI RMW22G24-EZ Triplex Standard Configuration is poorly made –average in quality, the shaft stripped out immediately after installation.

Tester says about this Product

“The replacement part was an exact match, but when you remove the defective pump, we SURE to notice the slit which holds a small piece of metal.

This MUST LINE UP connecting the little piece of metal to both the motor and the pump. If you fail to do this, the unit will not restore maximum water pressure. I thought it was as simple as pulling the defective one-off, and sliding in the new one.

BE SURE TO LINE UP THE MOTOR WITH THE PUMP before you fasten the unit back to the base. If you do NOT do this, trust me, you WILL need to follow this step to reengage your pressure washer.” By P Rivo

“I was torn between taking the risk that this would work. I am handy, but don’t do much with small engines. Might have taken me 15 minutes…max. And it works great. I found the hardest part was getting the old pump off.

I had to tap it with a hammer and it came off little by little. The new pump went on easily (4bolts is all it is). And it worked like new right away. Money well spent. I’ll update if it gives me any trouble.” By matcon

Average pump shaft

As light and pressure washers don’t make a big mess, we expected these pumps to last for a lot longer. However, after using the lights and pressure washers for about two months it actually destroyed the body of this pump shaft.

Tester says about this Product

“I replaced a Troy Bilt 020344 pump with this one. It seems well made and not cheap. It fit perfectly, it says you can choose which way to face the outlets, but I didn’t want to mess with it so I have to hook up the hoses from the front versus the rear, no big deal.

“I used this pump to replace a small one that I’ve and it just died. This replacement fit perfectly on my Craftsman machine (which had a 3,400 psi pump as well).

This one is a bit bigger than the one the engine had installed originally, but it fits perfectly and so far it’s working fine. I’ve used it several time and so far so good.

A few tips that you must consider, this is a small pump, for small jobs, don’t try to use it for 8 straight hours, if you do jobs like that, get an industrial one. If you’re using it for long periods of time, let it rest after 2 hours of use.” By J. C. Rivera

Things to Consider While Buying Best Pressure Washer Pumps

When choosing your pressure washer pump, there are a few things you should consider to find the best one for you

Size

When it comes to size, there are two things to keep in mind. First and foremost, how large is the pump, and do you have adequate space for it?

Pressure washer pumps are typically seven inches in diameter on all sides, give or take a few millimeters, but some can be as long as 11 inches.

Secondly, will it be compatible with your pressure washer? Take a look at the connection point and make sure it is compatible with your pressure washer before proceeding.

Water Pressure

You should also check the water pressure of the pump, which is measured in PSI and GPM (pounds per square inch and gallons per minute). Make certain that these numbers correspond to the model of your pressure washer.

Consider the following scenario: If your pump can handle a maximum PSI of 2500, but your pressure washer can handle a maximum PSI of 3500, you will never be able to utilize the entire maximum capability of your pressure washer.

Durability

The obvious goal is to purchase something that will last for years. The triplex pump is the most durable, and it may operate for thousands of hours or up to ten years without failure.

Another factor to consider is the type of material used in the pump. It is recommended to use aluminum or steel, or other strong metals, as a building material.

Budget

Pressure washer pumps are available in a variety of price ranges, ranging from $60 to $230, so be sure to stay within your spending limit when shopping.

Please be aware that triplex pumps are the most expensive and that wobble pumps are the most affordable.

Ease of Installation

The installation of some pressure washer pumps is less difficult than that of others. If this is essential to you, find out what the manufacturer and other customers have to say about how easy it is to install. It should take no more than five minutes to complete a simple installation.
