Controls
Direct displacement control
The LPV pump features Direct Displacement Control (DDC). The swashplate angle is set directly by a
control lever or linkage attached directly to the swashplate trunion. Control lever movement changes the
displacement and flow direction of the pump by increasing or decreasing the swashplate angle.
The control input shaft is on the right hand side of the pump. Contact your Danfoss representative for
availability of left side control input.
Features and benefits
•
Simple, low cost design
•
Pump output is maintained regardless of load.
•
Pump will return to neutral if control input is removed (if equipped with optional neutral return
mechanism)
Control handle requirements
Maximum allowable trunnion torque is 79.1 N•m [700 lbf•in]. Minimum available centering moment is 5.7
N•m [50 lbf•in]. The actual value will vary due to the influence of pump operating conditions. Maximum
swashplate angle is ±18°. For mating dimensions, see
on page 30.
