Product description

Notes
Before commissioning the system, the first running-in of the gear flow divider should be under no load.
Diagrams and circuit diagrams essentially valid as schematic diagrams also for 4-way flow dividers.
Description
This flow divider is used to supply four independent hydraulic circuits with just one pump.
Division error approx. 3 %.
Configuration of gear flow dividers: qi = Q/z * 1000/n.
Qi = displacement/section [cm³].
Q = total input volume flow [l/min].
Z = number of sections.
N = rotating speed [rpm].
Further information
Recommended speed: 1800 - 2000 rpm
