ATO S pump PVPC -C-5090/1D 11 PVPC-C-3029/4046/5073/5090/1D 11 PVPC-R-3029/1D -C-4046/1D hydraulic piston pumpProportional electrohydraulic controls for PVPC pumps pressure-flow alternate P/Q controls, analog or digital The variable displacement axial piston pumps type PVPC, can be supplied with advanced electrohydraulic proportional controls: • open loop pressure control; • load sensing flow control; • Open and closed loop P/Q controls; They allow to perform high dynamics and fine regulations, directly commanded from PLC or from the machine controller. They are available with separated driver or with integral electronics ቢ. New PES digital controllers, integrated to the pump, realize alternate closed loop controls of pressure, flow and max power limitation. The P/Q controls are also available with optional sequence module (LZQZR or PERS versions) that allow to operate the pump with minimum pressure in the circuit close to zero. Following communication interfaces are available for the digital PE(R)S execution, see section :ݟ • -PS: Serial • -BC: CANopen • -BP: PROFIBUS DP For technical characteristics and features of the PVPC pumps, see table A160.

A005 Pressure setting (only for PERS): 200 = 200 bar 1) pumps with ISO 3019/2 mounting flange and shaft (option /M) are available on request OPERATING CHARACTERISTICS Pump model Displacement Max working pressure / Peak pressure [bar] Min/Max inlet pressure Max pressure on drain port Power consumption at 1450 rpm and at [kW] maximum pressure and displacement External load position Max torque on the first shaft Max permissible load on drive shaft Speed rating Fax = axial load Frad = radial load Notes: For speeds over 1800 rpm the inlet port must be under oil level with adequate pipes. Maximum pressure for all models with water glycol fluid is 160 bar, with option /PE is 190 bar. Max speed with options /PE and water glycol fluid is 2000/1900/1600/1500 rpm respectively for the four sizes. A170 |
