Danfoss E Frame Open Circuit Axial Piston Pump Series 45

Danfoss E Frame Open Circuit Axial Piston Pump Series 45 features a single servo piston design with a cradle-type swashplate placed in polymer-coated journal bearings. Danfoss ERR Hydraulic Pump It comes with a bias spring and forces that cause the swivel plate angle to be increased. The servo piston makes the swivel plate angle smaller so that a proper fluid transfer is accomplished. There are nine reciprocating pistons that transfer fluid from the pump inlet to the pump outlet with the rotation of the cylinder block on the pump input shaft.

The block spring in the pump retains the piston slippers in the swashplate through the slipper retainer for optimal functioning. The cylinder block is supported by the bi-metal valve plate in order to optimize volumetric efficiency and minimize noise. Danfoss ERR Hydraulic Pump features tapered roller bearings for supporting the input shaft and Viton lip-seal against shaft leakage, thus making it suitable for long-term operation in the most demanding conditions. The Danfoss E Frame Open Circuit Axial Piston Pump Series 45 is developed in such a way as to have an adjustable spool arrangement, having either one spool in PC only or two spools in LS as well as two spools (LS and PC).

The control mechanism detects both system and load pressures (LS controls) and then adjusts it accordingly. Moreover, Danfoss ERR Hydraulic Pump has been made with the control ports system pressure to the servo piston to control pump output flow. This pump has been designed in such a manner as to be used in mobile applications as well as for industrial purposes.
