Notes:
(1) The displacements 14-20 use the same external casing.
(2) The values shown are valid for an absolute pressure (pass) of 1
bar (14.5 psi]) at the suction inlet port an when operated on mineral oil.
(3) Bypass included in the standard version
W1 14-20 series is a family of variable displacement axial piston pumps for use in closed circuits in cast iron.
The displacement is continuously variable by means of a tilting swash plate, and the oil flow direction is reversible.
The following range of controls is available:
Provisions for mounting auxiliary pumps are available:
and three accessory options:
Peak operations must not excide 1% of every minute.
A simultaneus maximum pressure and maximum speed are not recommended.
