unloader

[whamkabam]

I have a cat 2sfx30Gz1 pump. Will a northstarMV570 unloader work on this pump. Thanks in advance

I believe the Cat 2SG30 pump is rated for 3 GPM @ 2000 PSI,
(older 2SG30 pumps were rated 1200 PSi max)
and has a 3/8" Outlet and a 1/2" inlet. The MV570 unloader I can not find specifications on if it is rated for pressure from 1200 to 3000 PSI, and has a 3/*" inlet it should be OK.

I am partial to the AL606 unloader myself.

Hi mark

i was under the impression that they dont make the 606 anymore and now just have the 607?
Wont really matter to me because it work's great for me.

The AL606 is still being built, the AL607 is the same unloader with a heavier black spring.
