In most applications a general guideline is that the charge pump displacement should be at least 10% of
the total displacement of all components in the system. Unusual application conditions may require a
more detailed review of charge flow requirements. System features and conditions which may invalidate
the 10% guideline include (but are not limited to):
•
Continuous operation at low input speeds < 1500 min
•
High shock loading and/or long loop lines
•
High flushing flow requirements
•
Multiple low speed high torque motors
•
High input shaft speeds
Contact your Danfoss representative for application assistance if your application includes any of these
conditions.
