900 Table A0obs/E Axial piston pumps type PVPP, variable displacement, high pressure operation Hydraulic and electrohydraulic control obsolete components - availability on request PVPP-SLER-08/D PVPP are variable displacement axial piston pumps for high pressure operation and long service life, with low noise level, suitable for hydraulic oils or synthetic fluid having similar lubricating characteristics. The actual fluid displacement is dependent upon the length of stroke, of the pumping pistons. This length of stroke is determined by the position of the swashing plate that is achieved by a servo piston acting on one end of the swashing plate working against the combined effect of the off-setting forces of the pistons and centering spring on the other end. The rotating barrel, forces the pistons in a circular path in and out of the barrel and fluid displacement takes place. See section for a line of hydraulic and electrohydraulic controls for unlimited options of applications. The figure illustrates the advanced control of pressure and flow according to electronic signals. Displacement: from up to cm /rev. Pressure up to 0 bar.

MAIN CHARACTERISTICS OF VARIABLE DISPLACEMENT AXIAL PISTON PUMP TYPE PVPP Installation position Any position. The drain port must be on top of the pump. Drain line must be separated and unrestricted to the reservoir and extend below the oil level as far from the inlet line as possible. Suggested maximum line lenght is m. Loads on the shaft Axial and radial loads are not allowed on the shaft. The coupling should be sized to absorb the peak horsepower developed. Ambient temperature from -0 C to +0 C Fluid Hydraulic oil as per DIN... ; for other fluids see section Recommended viscosity -00 mm /s at 0 C (ISO VG - 00). Maximum start-up viscosity: 000 mm /s Fluid contamination class ISO / (filters at 0µm value with ß0 recommended) Fluid temperature T < 0 C, if T > 0 select /PE seals ONLY FOR PUMPS WITH PROPORTIONAL ELECTROHYDRAULIC CONTROLS type SL and SLE Coil resistance R at 0 C [Ω], Relative duty factor Continuous rating (ED = 00%) Max solenoid current [A], Max power [Watt] ELECTRONIC DRIVERS FOR PUMPS WITH PROPORTIONAL ELECTROHYDRAULIC CONTROLS The operation of pumps with proportional electrohydraulic controls is optimized in association with Atos electronic drivers, which have factory preset electronic calibration.

The RES unit also limits the pressure peaks on outlet line. () SLR and SLER versions can be used also for COMBINED PRESSURE & FLOW CONTROL coupled with the electronic card E-ME-K0PQ in Eurocard format which operates with P.I.D. logic on the pump reference signal according to the following block diagram. In this case a pressure transducer E-ATR (to be ordered separately) must be fitted in the system to feedback the actual pressure value of the line to the E-ME-K-0PQ making possible the pressure closed loop control.
