Look at specification data for hydraulic motors series OP standard version. Only the parameter Starting Pressure ismodified.
version “FR” these are the hydraulic motors with reduced mechanical losses , for wich at disengagedcondition ( unconnected with driving mechanism ) the rotation of the shaft could be realized by means of small torque.This advantage is especially usefull at operating with high frequencies of rotation (over than 300 min ) and low pressuredrop, which is inbred for types with displacements of up to 200 cm3. It is normal for these for the different condition ofoperation to have high torque, as well as high volume losses: the values of the volumetric efficiency are lower (up to 5 %for middle and up to 10 % for high values of the pressure drop), than these of the normal versions. That's why therecommended operatingfor “FR version is for applications with pressure drop up to 100 bar.
Additional advantages of “FR” version are prolonging of the life of the hydraulic motors at high frequencies ofrotation, as well as the possibility to use them in systems with big variation of the loading.

Low Speed Valve (LSV) “LSV” Series hydraulic motors have been designed to operate with normal pressure drop and toensure smooth run at low speed (up to 200 RPM), as the best security for operation is guaranteed at frequency of rotation20 ÷ 50 RPM . They have an increased starting pressure drop and are not recommended for using at pressure less than40 bar.Look at specification data for hydraulic motors standard version. The modification concerns only the followingparameters: maximum speed, maximum output,maximum Oil flow and maximum starting pressure.

Look at specification data for hydraulic motors series OP standard version. The modification concerns only theparameters: maximum torque,maximum output, minimum starting torque.
“LL” Series hydraulic motors have been designed to operate at the whole standard range ofworking conditions (pressure drop and frequency of rotation ) , but with considerable decreased volumetric losses in thedrainage ports. Their main purposeis to operateas series-connected motors in hydraulic systems.
For this version is permissible decreasing of the maximal torque with up to 5% (at middle speed) and up to 10%(at high speed) in comparison to the standard versions of motors.
