Response Time
The time required for the pump output flow to change from zero to full flow (acceleration) or full flow to
zero (deceleration) is a function of the size of the orifice and charge pressure in the control, charge
pressure, valve plates and other vehicle dynamics.
A range of orifice sizes is available for the Series 90 manual displacement control to assist in matching the
rate of swashplate response to the acceleration and deceleration requirements of the application. Testing
should be carried out to determine the proper orifice selection for the desired response. For more
information regarding response time for individual orifices, please contact your Danfoss representative.
