AXIAL PISTONS

PUMPS

Technical card  

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:

• Manual lever with feed-back
• Hydraulic proportional without feed-back
• Hydraulic proportional with feed-back
• Electric two position (ON-OFF)
• Electric impulse
• Electric proportional with feed-back
• Electric proportional without feed-back

Three through drive options for auxiliary pump mounting and two options are available:

• Through drive - SAE “A” 9T - 16/32-DP
• - By-pass

Peak operations must not excide 1% of every minute.
A simultaneus maximum pressure and maximum speed are not recommended.

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.
