This
compact, two stage, low pressure hydraulic
pump is available with either a 5hp Briggs
or 4hp Honda engine. When used
with the 4001D Pole Puller, the first stage
(to 1,500 psi) powers all retraction and most
lift operations. The second stage (from 1,500psi
to 2,800psi) gives the puller it's maximum
lift at a reduced ram speed.
