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.
Do the pressure washer pumps utilize oil and if so, do you need to check or change it?
Yes every pump is an oil filled pump when it is shipped. The PW2700 pump is “sealed” so you do not need to change the oil, the oil will last the life of the pump. On the PW3000 and PW4000 which utilize the triplex pumps it is recommended the oil be changed every season.
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.
