Frequently Asked Questions
What is the difference between DRG and DP control types?
Both DRG and DP are forms of constant pressure control, but they
are designed for different appliions:
• DRG (Remote Pressure Control): Allows the pressure setpoint for
the pump to be adjusted remotely via an external pressure control
valve.
• DP (Multi-Pump Parallel Pressure Control): Specifically designed
for systems where multiple pumps work in parallel. It contains an
additional element (a variable orifice, valve 5) that mechanically
links to the swangle. This design automatically compensates for
differences between pumps, ensuring they share the load equally and
operate at the same swashplate angle when working together at the
set pressure. The DP control has a larger control deviation (~6.5
bar) compared to DRG (~3 bar).
Why might multiple A4VSO DR pumps in parallel cause system
vibration?
When multiple pumps with standard DR controls are set to the same
pressure and run in parallel, slight inherent differences in their
response characteristics and pressure settings can cause them to
not reduce displacement (cut off) at exactly the same time and
rate. This lack of synchronization can lead to interactions between
the pumps, resulting in pressure fluctuations and potentially
causing severe pipeline vibration.
