Can I use any brand of pump parts to rebuild my pressure washer pump?
No. Only genuine ECHO Bear Cat or Annovi Reverberi parts and kits should be used to service or rebuild the pumps.
Can pressure washer pumps be rebuilt?
The pumps used on gasoline engine powered models can be rebuilt. ECHO Bear Cat has part numbers set up for pump rebuild kits that come complete with the seals, valves, etc. The pump on the PW1813E electric pressure is not rebuildable and will need to be replaced upon failure.
Is it bad to run the pump dry?
Absolutely. The water pump shaft and impeller are spinning at extremely fast rates. With no water to transfer their rotational energy to, that energy is released as heat instead. If the pump is run dry, its moving parts will become extremely hot, causing severe damage to the pump over time and greatly limiting its service life.
Pressure and Flow, and what causes water pressure.
Pressure and flow are inversely related–that is, if pressure is increased, then flow decreases, and
vice versa. “Pressure” is the amount of force per area, and “flow” is the volume of material moving
through a given area per second (not the same as velocity, which is the distance traveled per time).
Water pressure is caused by resistance to flow. If a force tries to move water and there is resistance
to that movement, then the water becomes pressurized. Consider a standard garden hose; when the
end of the hose is unrestricted, water flows out of the hose in large quantities, but without much force.
If you press your thumb over the opening, however, the stream of water that shoots out from around
your thumb will be much more forceful and will travel further, but there will also be less water per second
leaving the hose.
What are the most common types of pressure washer pumps?
Wobble, Axial and Triplex.
Wobble pumps are used on entry level electric pressure washers.
Axial cam pumps are more reliable and used most often on consumer grade pressure washers.
Triplex plunger pumps are more heavy-duty, serviceable, and most often used on quality contractor level pressure washers.
Who are the pressure washer pumps built by?
All pumps are made by Annovi Reverberi (AR) http://www.annovi-reverberi.com which is an Italian family owned business.
The PW2700 (5hp Honda GC160) model features an axial style, consumer grade pump.
The PW3000 (6.5hp Honda GX200) model uses a commercial grade, triplex plunger pump.
The PW4000 (13hp Honda GX390) model also uses a commercial grade, triplex plunger pump.
