4 GENERAL INFORMATION Fluid Use fluids with mineral oil basis and anticorrosive, antioxidant and wear preventing addition agents (HL or HM). Viscosity range at operating temperature must be of cst. For short periods and upon cold start, a max. viscosity of 800 cst is allowed. Viscosities less than 10 cst are not allowed. A viscosity range of cst is allowed for extreme operating conditions and for short periods only. Operating Temperature The operating temperature of the oil must be within -25 ºC 80 ºC. The running of the axial piston pump with oil temperature higher than 80 ºC or lower than -25 ºC is not allowed. Filtration In order to improve the control of the fluid contamination levels the pumps can be equipped with a charge flow filter positioned on the delivery outlet of the charge pump. Only the flow necessary to reintegrate the oil lost due to leakage will pass through this filter, all the excess flow, which is discharged through the charge pump valve is therefore not filtered to ensure a longer life of the filter cartridge. The filtering cartridge (microfibre) is a 22 micron absolute grade (10 micron nominal). In order to ensure a correct functioning of the unit, the max. permissible contamination level in the circuit is 20/18/15 according to ISO Suction Pressure The minimum pressure on the charge pump suction must be of 0.8 absolute bar. On cold starting and for short term an absolute pressure of 0.5 bar is allowed. In no way inlet pressure can be lower. Operating Pressure Main Pump The maximum permissible continuous pressure on pressure ports is 250 bar. Peak pressure is 350 bar. Charge Pump The nominal pressure is bar; Standard 20 bar; Maximum admissible pressure is 35 bar. Case Drain Pressure Maximum case drain pressure is 2 bar. On cold starting and for short term a pressure of 6 bar is allowed. A higher pressure can damage the main shaft seal or reduce its life. Seals Standard seals used on pumps are NBR. In case of use of special fluids, contact our Technical Department. Displacement Limiting The pump is equipped with the displacement mechanical limiting device. Displacement limitation is obtained by means of two setting screws which limit the control piston stroke. Pag. 4 HT 16 / M / 501 / 1009 / E

5 GENERAL INFORMATION (continued) Product Description Series is a family of variable displacement axial piston pumps for use in closed loop circuits. The displacement is infinitely variable by means of a tilting swash plate, the oil flow can be reversed over the neutral point. Various controls are available: manual, servo-control lever operated, electric, etc.. Each pump is provided with a charge pump that makes up for internal leakage, maintains a positive pressure in the main circuit and provides oil to the control system. All pumps have maximum pressure relief valves and can be supplied single or tandem version. Different through drive options are available for auxiliary pump mounting as well as a wide range of options: by- pass valve, pressure filter and others.

13 CONTROLS Automotive Control (AM2 - AM4) The automotive control pump has the function of automatically adapt the displacement to the variation in the number of revolutions of the pump (and thus of the diesel engine); set the number of revolution at which the machine starts up and limit the power absorbed by the transmission to the diesel engine output. The inching valve (variable restrictor) is available as optional, with mechanical or hydraulic control version. (Installation drawings see pages 8 and 9).

18 CONTROLS (continued) Electric Proportional Control with feed-back (ER 2 - ER 4) The displacement of the pump is directly proportional to the input current of one of the two proportional solenoids. Flow direction depends on which solenoid is energized. Standard solenoids are proportional with 24V d.c. max. current 1A. (Optional solenoids 12V d.c. max. current 2A).

19 CONTROLS (continued) Electric Impulse Control (EI 2 - EI 4) Impulse control is where the displacement of the pump is in function of the number of inputs of current to one of the two solenoids. The servocontrol is without zeroing spring, therefore the piston of the servocontrol stays in the position until a new input of current is fed to the solenoids. Flow direction depends on which solenoid is energized. Standard solenoids are ON-OFF with 24V d.c. max. current 1A. (Optional solenoids 12V d.c. max. current 2A).

21 OPTIONAL Power limiter (01) The power limiter has been designed to work only on pressure port line A of the pump. When the power setting is reached, the pump will destroke as the pressure increases. The setting of the power limiter is not externally adjustable and must be stated in the purchase order, please contact us for further details. Power limiter HT 16 / M / 501 / 1009 / E Pag. 21

22 OPTIONAL (continued) Electric Cut-off (P1 - P2) The electric cut-off valve, brings to zero the displacement of the pump when power supply to the ON/OFF solenoid is cut-off. Feed voltage is 12V d.c or 24V d.c. The electric cut-off valve can be assembled on pumps equipped with one of the following controls: IND - INP - LRX. It is not possible to assemble the cut-off valve with power limiter and in the tandem pump short version. Connector DIN 43650A Pag. 22 HT 16 / M / 501 / 1009 / E

23 OPTIONAL (continued) Charge pump filter with clogging sensor on delivery side (FE) In order to guarantee an optimum stability of the fluid contamination conditions the pumps can be equipped with a filter positioned on the delivery outlet of the charge pump. Only the flow necessary to reintegrate the lost oil due to drainage will pass through this filter, all the excess flow, which is drained by the charge pump valve, is therefore not filtered, in this way it is guaranteed a longer life of the filter. Upon request it is possibile to add an electrical filter clogging sensor (Connector DIN 43650A). The filter is supplied upon request. Electric sensor Electric sensor HT 16 / M / 501 / 1009 / E Pag. 23
