Q: I installed a new AR RMV25G30D pump on my 6-year old Troy-Bilt power washer with a Honda GC160 motor. The clearance of the hose connections to the power washer frame is tight but workable. I note that the pump flange would allow me to rotate the pump counterclockwise on the engine shaft by about 40 degrees (or 90 degrees) which would eliminate the hose connection clearance difficulty entirely. My question, is it okay to mount the pump with its body horizontal but rotated with the valve heads not being horizontal?
by David from Missouri on August 07, 2016
A: Please contact the AR folks directly at 866-235-5112 to find out if changing the installation will affect the performance of their pump. by Brian, Product Expert
Q: I have a Dewalt DXPW3835. Will this work OK as a replacement pump.
by Terr from Colorado on July 04, 2016

A: I'm sorry, we don't sell DEK units, and there isn't a cross-reference where I could look it up for you. You may want to give the folks at AR a call, toll free, at 866-235-5112. They should be able to advise you if this pump will fit. by Brian, Product Expert
Q: I have a Devilbiss Excell 2400 PSI unit with a DAPC Axial Cam Model 18219 265684. Engine is 5 HP.
I need to replace the pump unit -- what model should i get?
by Tom Martin from New Jersey on May 25, 2015
A: In order to make sure it is compatible with you machine you need to be sure of a few things. 1. Engine shaft diameter size 2. What is the HP or CC of your motor 3. The number of bolt holes your pump has 4. Whether your pump is horizontally or vertically mounted After knowing those things we can better assist you in which replacement pump is right for you. by Brian, Product Expert

by Corey from Indiana on October 27, 2014
A: This pump is not serviceable or rebuild able. You would need to purchase a new pump. by Brian, Product Expert
Q: Hi Mike, I have an AR pump model SJV 3G27-1 on a Troy Bilt pressure washer. I can only get 1100 PSI of pressure. I tried to increase the pressure by the pressure reg (Unloader) but can not get past 1100 PSi. HELP
by Rich from Pennsylvania on September 10, 2014
A: I apoligize for the issues you are having. I would recommend reaching out to the folks at AR for troubleshooting and service center locations. Their number is 866-235-5112 by Brian, Product Expert
Q: Bill, I have a Pressure washer the has an AR-RMV2.5G27D pump on it. It works great and I was wondering if there would be anything wrong with running water from a basic hater heater, approx. 160 degree, through it. What could happen to it? Thanks, Jim
by Jim on January 21, 2012
A: No, you could not run that hot of water thru your pump. You would literally end up melting the seals after 1 or 2 uses. Using hot water thru a "cold water" pump is the quickest way to damage a pump and cause it to stop creating pressure. Pumps like the one you have can only accept water up to 104 F degrees by Brian, Product Expert
Q: I need to match up the pumps. I bought 2 already and had to send them beck. I need pics of the face where it mounts the motor
by Damian from Louisiana on May 09, 2011

Q: I need to replace a Devilbiss PK16331 Pump. It is on a Honda 5 HP motor. The original Presure Washer Mopdel # is WGCH2225 Will the RMV25G30D replace this Pump?
thanks in advnace.
by Dale from Ohio on April 17, 2011
A: As long as your Honda engine has a 3/4" shaft on it, then yes this pump will mount up perfectly. Also, this is a horizontal mounted pump and cannot be mounted vertically. Given the HP size of your existing engine, you might want to consider purchasing a model SJV25G27D-F7. You will more than likely not be able to push the full 3000 psi with the size of your engine which could cause strain on the pump and shorten its lifespan. by Brian, Product Expert
Q: Hi Bill, I have a Karcher G2000MK 2000PSI 2.0GPM 87cc gas powered pressure washer.Would this pump AR 3000PSI 2.5GPM 3/4 hollow shaft replacewment pump model # RMV 25G30D be a suitable replacement for the one on my machine?
by Victor Sqiires on April 17, 2011
A: As long as you have a 3/4" shafted engine then yes it would mount up just fine. However, the engine size you have is definitely not powerful enough to provide the full 3000 psi. If your engine has a 3/4" shaft, you would be better off purchasing a model SJV25G27D-F7 replacement pump given the size of your engine. by Brian, Product Expert
Q: where do you add the oil in a preasure washer pump
by Richard Forrester from Alabama on April 04, 2011
A: Certain style pumps cannot have the oil changed or added. These are sealed pumps and will normally be labeled as "Axial Cam" style pumps. "Triplex Plunger" style pumps can have oil added and/or changed. If you have this type of pump, there will be a fill port on top of the pump that unscrews. You will also have a threaded plug on the bottom of the pump so that you can drain the old used oil. by Brian, Product Expert
Q: which turbo tip would you recommend for this pump after attached to a honda engine?
by Greg from Florida on April 03, 2011
A: You would want to use a 3.0 size orifice when purchasing a turbo nozzle or spray tip for use with this pump. The exact turbo nozzle needed for this pump would be model # AL-TPR25-30A by Brian, Product Expert
Q: I have an RMV2.5 3k psi pump on a Robin/Subara 6 hp engine (Ridge Brand Washer). It does not pump water out of the nozzel under pressure. What might I look for. I have check the hoses. It is about 1 year old
by Mark Carmouche from Louisiana on March 28, 2011
A: Your problem would either be coming from the unloader valve sticking or the seals within the pump are blown. The only way to truly find out what the problem is, is for you to take the machine to a service center that repairs pressure washers and have them test it. Regardless, the seals on this pump cannot be replaced and the unloader valve would probably cost 1/2 the amount to replace as it would to purchase an entirely new pump. by Brian, Product Expert
Q: I need a new 2500-3000 psi pump to replace my existing. I have a 5 hp honda engine and need to know what details you need to size the correct replacement pump.
by Dave Moeller from Indiana on March 27, 2011
A: This particular pump will definitely mount up to a Honda engine flange with no problem. One thing you have to confirm on your end is the engine shaft size. This pump has a 3/4" shaft and would only fit engines with a 3/4" shaft too. More than likely your engine does have a 3/4" shaft but there are also 7/8" and 1" shafts on engines made so it is always best to verify before you make the purchase. Also, this is a horizontal mounted pump and cannot be used in vertical applications. by Brian, Product Expert

 When the axial pump on your pressure washer wears out it can't be rebuilt the way our "Better" and "Best" triplex picks can.
However, if the engine is still running strong it can be very cost effective to replace an axial pump, and with this unit from AR it's not all that hard to do.
It matches easily to a standard 3/4" gasoline engine flange, and will push up to 2.5 gallons per minute at up to 3000 psi, so it works great for 5 to 6.5 horsepower engines.

 Replacement Pump EZ replacement and works fantastic, I think better than when new!
Only issue- this pump required narrow profile socket head bolts for mounting due to its profile. My original flange was flat & used standard hex head bolts.Those hex heads were too large to fit in the recessed profile of new pump. Perhaps vendor should foot note this in product description.
Overall satisfied.

Great Product, Super Easy
Great product. Super easy to install. The only trouble I had is that for the mounting hardware, std. American thread bolts were supplied, and I needed metric, so had an extra trip to the hardware store.

Great Pump At A Great Price
The AR 3000 PSI unit works very well. I had to release the pressure relief valve quarter of a turn counterclockwise and now it's perfect.
Great pump at a great price.

 Perfect Fit, Great Value
Well I will tell you first I'm unfortunately not a mechanic, so I took my Briggs and Stratton Elite series pressure washer to a local small engine repair shop and told me the repairs to my pressure washer would be over $400, he told me it would be better to go and by a new one.
So I did a Google search and Pressure Washers Direct came up. Did some searching for new ones, then seen the menu for pumps, did some research, purchased the pump, received in less than a week.
Took me about 1 hour and it works fantastic, and saved myself $250 and have pretty much a brand new pressure washer. Thanks for all your help PWD!!!

Couldn't Be Happier
This new pump RMV25G30D3000PSI works great on my 5HP Honda CV160 engine. There was a 2400 PSI on it to start and I replaced it with this unit.
I couldn't be happier with this pump. A lot more pressure than the old one.
Thanks a lot for the advice you gave me when I emailed you before I ordered it.
PWD RESPONDS: As a safety precaution, please make sure your pressure washer parts (gun, hose, & tips) are rated for the increased pressure.
If your hose is not stamped with the burst pressure, then check your Owner's Manual or call the manufacturer for the information. More pressure than the equipment can handle could result in injury or damage! This new pump RMV25G30D3000PSI works great on my 5HP Honda CV160 engine.

Good Pump
Fast delivery, easy install, works great. I had a company install this same pump to replace a bad one several years ago and it cost me $325.
This is a good deal if you can install it yourself. Allen wrench required but not supplied. Mounting bolts are provided with the pump. Ask for an install manual when you order.
