Q: With Simpson professional4200 psi gas cold water belt drive washer what brand of pump it has. In your website only states triplex plunger.
by Manny from New Jersey on June 01, 2012

A: Simpson uses an industrial grade, triplex plunger pump on this unit, but they will choose between available brands for the best balance of performance and price.
by Brian, Product Expert
Q: Hi Bill,

What's the real difference between the Simpson Professional 4200 PSI P.W. and the Pressure Pro 4000 P.W. Also, why is a belt driven engine pump combination better than direct attachment? Thanks! V/r Les

by Les McPeak from Illinois on May 19, 2011

A: Ideally, there is not going to be a huge difference withe the Pressure Pro and the Simpson, both are high quality models. The Pressure Pro units do give you a little more tlc being they are all built as the order comes in and don't come off of an assembly line, but the quality is still there on either unit.

The benefits of a belt driven unit is the pump is going to run at half the RPM as a direct drive. A belt driven pump is going to run at an RPM of about 1740 and a direct drive runs at or around 3250-3600. This is going to put less pressure on the pump and give you a longer lasting product. In alot of cases it really can depend on how much you use the unit. If you are just looking for a high quality pressure washer for your home and some other odd jobs, a direct drive unit is more than fine, but if you are using for business and multiple tasks and it will be getting alot of use, a belt drive is a better way to go.

Thanks,

Try One You Will Like It !!!!
Received the pressure washer in a box in a tractor as you advised..the pressure washer is completely assembled.

I had to buy some some speed connects for the wand. Put in oil that was included and added fuel and as usual with one of those dependable Honda motors pulled the cord a couple of times and she fired right up.

I have several power washers both cold water and hot water but they do not compare to the U.S.-made belt powered power washers. The only bad thing is I do not have funds to... more

An Awesome Pressure Washer
I love it. More power than I need and the pressure reducer makes that variable need for pressure available with the turn of knob. I only wish I had known it was available with an electric start. The kickback can sometimes be impressive. If I can get the electric start as an additional add on I will get it and I suggest that anyone buying this product does the same. Other than that it delivers great water pressure and runs smoothly.

I have mounted it to my pickup that has a bed slide. ... more

Michael,
You may want to give the folks at Simpson a call at 877-362-4271 to see if your unit can be retro-fitted with an electric starter. There are aftermarket electric starters on the market, but you need to make sure you choose one that is compatible with your engine.

Simpson Waterblaster Professional 4200 Psi (gas-cold Water) Belt-drive Pressure Washer W/ Honda Engine Review
(No, I am not the race car driver). This machine is really slick. Lots of power, easy to start, clearly the best pressure washer I ever owned. I started my pressure washer business 5 years ago and swear by these Simpson machines. I used to buy cheaper brands but am totally convinced to buy the best, which is Simpson. The Honda engine is great and the belt drive system is much better for the amount of use I put on these machines than the direct drive. Really nice hose doesn't mark stuff... more

Does The Job
I bought this unit as an addition to my other pressure washer that I use as a back up at my presently fledgling part-time business, and it does a superb job cleaning concrete and wooden decks alike.

The only issue I had was, when I received the unit, I noticed that the label affixed to the frame stated that the triplex pump was 3.5 GPM instead of the advertised 4.0 GPM. I then contacted PressureWashersDirect and had kind of a hiccup in getting a response from them.

It took the... more

Benny,
I apologize, Simpson was looking into this. At this time they are moving their facilities, which is the reason it took them 3 business days to get back to me. Again, I apologize for the delay, but the pump is rated for 4.0 GPM.

Non-functional
I purchased this item for clearing gutters with a telescoping pole. I don't recommend purchasing this item at all for the following reasons:

Due to the design, when using pressure above 3000psi, the extension pole flexes way to much and becomes uncontrollable, and a safety hazard.

For some weird reason, the tips keep shooting off into the gutter, so I have to drop a ladder to retrieve them.

Finally, I would recommend the one at a big box store where there are two nozzles pointing... more

James,
The pole is rated to 3500 PSI. Using it with a 4200 PSI washer may be enough to over-flex the pole, however safety procedures are covered in the Owner's Manual.

The gutter cleaner is 1/4" tip; the pole is 3/8" tip. You will need an adaptor for the proper fit.
