5 SPECIFICATION DATA for...lsv Low Speed Valve (LSV) LSV Series hydraulic motors have been designed to operate with normal pressure drop and to ensure smooth run at low speed (up to RPM), as the best security for operation is guaranteed at frequency of rotation RPM. They have an increased starting pressure drop and are not recommended for using at pressure less than bar. Look at specification data for hydraulic motors standard version. The modification concerns only the following parameters: maximum speed, maximum output, maximum Oil flow and maximum starting pressure. Max. Speed [RPM] Max. Output [kw] Max. Oil Flow [lpm] Max. Starting Pressure with unloaded Shaft, ,0 5, ,0 7, ,2 8, ,0 8,8 2 6,8 8, 1 6,2 7, ,8 7, ,2 6, SPECIFICATION DATA for...ll Low Leakage (LL) LL Series hydraulic motors have been designed to operate at the whole standard range of working conditions (pressure drop and frequency of rotation ), but with considerable decreased volumetric losses in the drainage ports. Their main purpose is to operate as seriesconnected motors in hydraulic systems. For this version is permissible decreasing of the maximal torque with up to 5% (at middle speed) and up to % (at high speed) in comparison to the standard versions of motors. Look at specification data for hydraulic motors series standard version. The modification concerns only the parameters: maximum torque, maximum output, minimum starting torque. Max. Torque Max.

It is normal for these for the different condition of operation 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 % for high values of the pressure drop ), than these of the normal versions. That's why the recommended operating for FR version is for applications with pressure drop up to 0 bar. Additional advantages of FR version are prolonging of the life of the hydraulic motors at high frequencies of rotation, as well as the possibility to use them in systems with big variation of the loading. Look at specification data for hydraulic motors series standard version. Only the parameter Starting Pressure is modified. Max. Starting Pressure with Unloaded Shaft, ,5 5,5 4
