PTO-driven pressure washer

/ PTO-driven pressure washer #2  
Wow! That's a pricey pump. I guess it's the overdrive gear box. Can't really tell what Comet pump is used but pumps with the same delivery rate would put the absorbed power in the 10-12hp group. The overdirve gear box might add another 5hp.

However; The "SW5540" designation in the model# matches a Comet pump SW5540 with 5.5gpm @ 4000psi and it's absorbed power is 14.5hp at 1450rpm. The overdrive gear box is going to absorb some power so I'd bet on at least 20hp.

Hope this helps
Ken
