I found this video exploring why the electric 2500 PSI Greenworks GPW2500C pressure washer with a triplex pump is about twice as expensive as it's non-commercial cousin, the 3000 PSI GPW3001, that has a cast aluminum axial cam pump. It looks like the pump is just that much more expensive. What's unclear is why it's rated 500 PSI lower than the non-commercial version when you mention that triplex pumps typically run a much higher PSI than that. It's also only rated for 1000 hours and does not require maintenance. The PSI, lifespan, and serviceability all seem to be in contrast to what you mention about this type of pump.

I appreciate the clear explanations.
I believe the first one is an “axial cam” pump and the second one is an “axial piston” pump.
Thank you for this content. Very helpful
