I will be buying a new washer soon, but was wondering about the alum vs bronze pump. I have been told that the alum pump is inferior to the bronze one. Any experience with these?
 
We've got both at work - a cheap-o aluminum pump that is approx five years old and a bronze pump that is one year old.

Haven't had problems with the aluminum pump yet and it's seen more use than a typical homeowner would've given it.
 
You probably will not find a good Cat pump on a reasonably priced pressure washer at Lowes or HomeDepot.

Spend what you want but keep it from freezing and no more than a minute or two of running with trigger off and it will last many years of homeowner use.
 
I had an auto shop teacher point out that it's the on/off cycles that seem to kill the electric home owner style units. I just keep the trigger locked on all the time and turn off the unit if needed. I have yet to kill the pump on one yet.

You will use it for all kinds of jobs.


If your doing a gas motor unit, Honda has been very good to me in terms of long lasting out doors power equipment motors.
 
I looked at a 2500 PSI Craftsman today with the Briggs engine and it has the alum pump. I may buy it. So don't run the washer with out spraying water? When spraying, I guess water flows through the pump and lubricates it?
 
With a gas one when you release the trigger the pressure goes up instantly. An unloader is present which vents the water back to the intake. In a circle. But each pass heats the water. Finally it melts some of the plastic/nylon parts in the pump. The unloader can be part of the pump or plumbed externally.

Now if your in the mobile business and come with a large water tank, they vent the unloader back into the tank, so you could probably go to lunch and leave it running. But I doubt that is what your are doing.

You can buy rebuild kits for most pumps. Assuming the housing did not freeze and crack.
 
While on this topic, is the pink RV antifreee ok to use for the winter? I was hoping it would not degrade the pump parts.
 
I have mentioned this before; Briggs & Stratton Synthetic pump oil. Thats what I use in my Faip one season wonder pumps. Works very well.
 
My pressure washer has an Annovi aluminum pump that has held up well and still works great at a few years old, but I have seen plenty of failures with the aluminum pumps too. A Cat or General pump is the way to go if durability and serviceability are critical.

Briggs and Stratton Pump Saver works great for protecting pumps in winter.

our local Home Depots are selling out inventory of Subaru engine equipped Ridgid 3000 psi units with CAT pumps for 499, great price, nice units with automatic pressure relief systems and automatic idle down engine control systems.
