INTRODUCTION - GENERAL INFORMATION Carefully read the use and maintenance manual before start-up the motor. The use and maintenance manual must be placed near to motor installation location in order to guarantee operators easy access to the instruction manual. For further information please contact Italgroup. Motor description HC series motors are radial piston hydraulic motors (generally indicated as LSHT motors, low speed high torque motors) with a rotating shaft (1) and a stationary housing (2). The pistons (3) are located radially and the working fluid provide the mechanical force that...

HCD - MOTOR TECHNICAL DATA Theoretical torque Max cont. speed (refer to next page for HSM version) Peak speed Max. (**) (refer to cont. next page for power HSM version) (*) Peak power For all motors: - Hydrostatic test pressure: see motor datasheets; - Refer to motor performance diagrams for more information - (*) For motor operation with a continuous duty cycle at maximum continuous power the flushing is usually required. For more information please contact our technical department. - (**) Do not exceed peak power. The data specified into the catalogue are for product description purpose...

HCD - MOTOR TECHNICAL DATA - HSM VERSION H YDRA ULtC US TOPS Size Displacement Theoreti- Max Peak speed The HSM version is a special configuration with balanced shaft, in order to erase or reduce to very low values the motor vibration due to the motor rotation at high speeds. In this way the motor can works at higher speeds in a more efficient and less noisy way. In order to obtain the motor performance graphs for HSM version, please contact Italgroup technical department. Motor type Balancing flange additional thickness For all motors: - (*) For motor operation with a continuous duty cycle...

HYDRAULIC FLUID RECOMMENDATIONS Fluid selection In general, we recommend the use of hydraulic oils with minimum viscosity index of 95, with anti-wear additives (ISO HM and HV). Once normal working temperature is reached, the drain oil viscosity must be at least 20 cSt, preferably in the range from 30 to 50 cSt. HE oils (ecological fluids) are allowed, but must be used with particular attention, because them can influence the motor seals compatibility, and can reduce motor performances and life. Please contact us in case of HE oils usage. Optimal viscosity selection Referring the first...

HYDRAULIC FLUID RECOMMENDATIONS Hydraulic systems oil must always be filtered. The choice of filtration grade derives from needs of service life and money spent. In order to obtain stated service life it is important to follow our recommendations concerning filtration grade. When choosing the filter it is important to consider the amount of dirt particles that filter can absorb and still operate satisfactorily. For that reason we recommend filters showing when you need to substitute filtering cartridge. · 25 μm filtration required in most applications · 10 μm filtration in closed circuit...

Arrange piping in a way that the motor cannot drain off and cannot generates air bubbles into the motor case. Under certain conditions may be is necessary to arrange a check valve in order to help avoiding the motor drain off. Always check...
