PV040, PV046, PV063, PV071, PV080, PV092, PV140, PV180, PV270, PV360 hydraulic parker PV axial piston pump
With thru drive for single and multiple pumps
Swash plate type for open circuit
Technical Features
• Mounting interface according to VDMA-standards sheet 24560 part 1
• Standard: 4-hole flange ISO 3019/2 (metric)
• Large servo piston with strong bias spring achieves fast response; e.g. for PV042 upstroke < 75 ms
down stroke < 45 ms Note: Follow installation instructions.
• Reduced pressure peaks due to active decompression of system at down stroke
• Also at low system pressure reliable compensator operation. Lowest compensating pressure 12-15 bar
• 9 piston and pre-compression technology (pre-compression volume) result in unbeaten low outlet flow
pulsation.
• Rigid and FEM-optimized body design for lowest noise level
• Complete compensator program
• Thru drive for 100% nominal torque.
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
