AR Annovi Reverberi RMW2.5G28-No Key or Thermal Valve
By far the question we are asked the most is how to tell which pump the customer has.  AR does label their RMW pumps but they do not mark on that label whether it is the EZ or the EZ-SX pump.  There are two ways to tell which pump you have.  The first way is to look at the direction your inlet and outlet tube face in relation to where the spark plug is located.  If the tubes go out the same side as the spark plug then you have the EZ version.  If your inlet and outlet tube come out opposite the spark plug then get the EZ-SX version of the pump.  The second way to tell which version you have is lay the three legs of the pump flat on a table with the inlet and outlet tube facing you.  Look at the legs of the pump and take note of the leg that has large hole in it.  If that leg is positioned at 2 o’clock then you have the EZ version.  If it is at 7 o’clock then you have the EZ-SX version.

How To Determine What Pump the Customer Needs–Vertical Shaft
1)  Is your pump a vertical shaft or a horizontal–vertical shaft pump is under the motor and the horizontal shaft is on the side of the motor–a vertical shaft motor for pressure washers usually has a 7/8″ shaft and the horizontal motor for the smaller pumps is usually a 3/4″ shaft.  As you increase in horsepower the crankshaft goes from 3/4″ to 1″ or larger on the horizontal shaft motors.
2)  If you have a vertical shaft pump what horsepower is your motor?   If you have a a 3.5 to 6.5 hp motor which will produce 1900 psi to 2550 psi then we recommend the RMW2.2G24EZ or the RMW2.2G24EZ-SX depending on the direction the tubes go out.  If they come out the same side as the spark plug then you will need the RMW2.2G24EZ.  If the tubes go out opposite the spark plug then you will need the RMW2.2G24EZ-SX.
3hp to 6.5 hp—1900 psi to 2550 psi—RMW2.2G24EZ or RMW2.2G24EZ-SX
6.5hp to 7.75hp—2550 psi to 2700 psi—SRMW2.2G26EZ or SRMW2.2G26EZ-SX
7.75hp to 8.75hp—2700 psi to 3000 psi—RMW2.5G28EZ or RMW2.5G28EZ-SX
3)   The exception to the rule is if you have a crankshaft that is 2″ or longer.  If that is the case they will need the RMW2.5G26D-F7
Tubes go out spark plug side——  EZ version of the pump
Tubes go out opposite the spark plug—–EZ-SX version of pump
***Note: While there are cheaper replacement vertical pumps out there not all pumps are the same.  AR axial pumps come with a 1 year warranty while the cheaper priced ones come with a 30 day warranty. Another reason to consider buying AR Pumps is for parts.  Can you get parts for your pump if something minor goes wrong?  In our repair shop we have worked on thousands of pressure washers.  Our biggest problem we face when the cheaper pumps come in for repairs is if we can get parts for them – and many times the answer is no.  All the pumps we sell we can get parts for ( even if they are made overseas) or have them in stock.***

You simply remove your old pump and bolt the new one on. We also have extra items that we recommend you to purchase with your pump. We list the item number for you to copy and paste to quickly find their listings. These pumps do not have a thermal relief valve on the pump-we recommend you buying the thermal valve to protect your pump from overheating. The thermal relief valve is $9. If you have the Devilbiss oil-less “bowtie” pump you will also need the key to connect your motor crankshaft and the pump shaft- the link is below. The key is $2. We also have pump saver which is used to protect your pump from corrosion.  Also listed below are the correct size spray tips for your pump and 25′ pressure washer hoses rated at 3200 psi. If there is anything else you are looking for that you do not see in our store call or email us. More than likely we have it. If you are unsure if this is the right pump for you please call us at or email us through eBay and we can help you out. We have been working on pressure washers for more than 20 years and can help you troubleshoot your problem.
