Atos PFR-315 Pump

Table A045-14/E
Radial piston pumps type PFR fixed displacement
f
PFR are fixed displacement radial piston pumps with positive drive construction of
the pistons c (without return spring) for high performance and low noise level.
IN
They are available in three different body size and single, multiple or with throughshaft configurations.
