Avoid using MIL-spec. hydraulic fluid, high water base hydraulic fluid (HFA), or spindle oil. Maintain the fluid temperature inside the tank in the range to 4 C when using a water-glycol hydraulic fluid or water/oil emulsion type hydraulic fluid. Recommended contamination level of hydraulic fluid Operating pressure MPa Up to.7.7 to.6 Over.6 Recommended ISO class /8/ 9/7/4 8/6/ contamination level NAS class 9 8 Use clean hydraulic fluid that satisfies the recommended contamination level for the operating pressure. Installation and alignment Ensure that the eccentricity of the drive shaft and pump shaft is no greater than. mm (TIR), and run the pump with no force acting perpendicularly on the pump shaft. Misalignment between the shaft centers will cause damage to bearings and oil seals, generate noise and vibration, and lead to pump accidents. Avoid crosswise drive using a belt, chain or gears (it will cause noise generation or damage to the bearings). The pump shaft can be installed vertically. Restrict the clearance between the spigot joint of the flange and the hole to +. to +. mm in diameter. Restrict the clearance between the key shaft and the coupling hole to +. to +. mm in diameter. Filters Use a suction filter with meshes per inch at the inlet side. In the return line to the tank at the discharge side, use a line filter with a filtration accuracy of μm or better. For delivery pressures of 4 MPa {4 kgf/cm } or greater, use a line filter with a filtration accuracy of μm or better. Piping Ensure the suction port is airtight. Aeration will cause abnormal noise. When using steel pipes for piping, take care not to force the pump off center. Forcing the pump off center with pipes may cause abnormal noise. At start Fill inside the pump and the hydraulic system with the hydraulic fluid before starting operation. After checking that all hydraulic circuits and electrical circuits are ready for operation, set the hydraulic circuit at the load side in the no-load status before starting the pump. When the pump is driven for the first time, turn the power switch to the motor on and off a few times to let the air out of the piping and then run it continuously at full speed. At a fluid temperature of 7 C or lower, warm up the pump by running it at a pressure of MPa maximum and increase the pressure when the fluid temperature has risen. (Note that the pressure must be.7 MPa minimum.) If there is a temperature difference of C or greater between the pump and fluid, warm up the pump to reduce the temperature difference to within C before running it. Suction pressure Keep the suction pressure within the permissible suction pressure of the pump. High suction pressures will generate cavitation and cause damage to the parts, noise, and vibration, resulting in a shorter pump service life. The discharge pressure must always be larger than the suction pressure.

18 Starting up procedure and points to note (DE, DEV) Supply fluid from either the pump's discharge port or suction port before starting the pump. Avoid piping where both of the ports are installed downward. As far as possible, try to arrange the oil tank and the pump such that the oil level in the tank is higher than the pump position. If the oil tank needs to be arranged such that the pump position is lower than the oil level, keep the piping length as short as possible and be sure to supply fluid into the pump casing from either the discharge port or suction port before starting the pump. The pump usually starts suctioning and discharging the fluid within two to three seconds after it is started. If no fluid is discharged, check for resistance at the suction side of the pump, aeration, and removal of air at the discharge side. Air has to be removed from the hydraulic system to enable suctioning by the pump when starting it for the first time. If it cannot be removed, implement the necessary measures, such as loosening the pipe joint at the discharge side or providing an air bleeding valve to enable removal of air. If the pump does not suction or discharge even after such measures, increasing the of the pump may help. Follow the guideline below for the of the pump when starting it for the first time. Guideline for of the pump when starting it for the first time DE series DEV series min minimum 8 min minimum If the oil level is lower than the pump position and insufficient If the oil level is lower than the pump position and insufficient priming fluid is supplied at the start, it may be necessary to run the priming fluid is supplied at the start, it may be necessary to run the pump at min or higher. pump at min or higher. When starting the pump at a lower than the guideline above, it is advisable to have the oil level in the oil tank higher than the pump position. Once the pump has started suctioning and discharging, securely fasten the connections at the discharge side that were loosened earlier. At the initial operation of the pump, run it for to minutes with no load to remove air in the hydraulic system. When the entire system has filled with fluid with the air fully removed, the pump can run under the regular operation conditions. The operating conditions while the pump is running are as follows. DE series DEV series Minimum Recommended suction pressure to.4 MPa to.4 MPa Permissible suction pressure.7 to.68 MPa.7 to.4 MPa Recommended hydraulic fluid viscosity to 4 cst to 4 cst Maximum viscosity at start cst 86 cst When the pump is stopped for a long time, or when building a system where fluid inside the discharge/suction piping of the pump is drained when the pump is stopped, arrange the suction piping of the pump in the direction that prevents the fluid inside the pump casing draining out. By orienting the suction/discharge port upward or sideways, fluid is retained inside the pump on starting it after it has been stopped for a long time, and dry running of the pump can be avoided. When starting the pump after it has been stopped for a long time, follow the procedure and pay due attention to the points to note given above again. The condition of fluid inside piping in relation to the time that the pump has been stopped varies depending on the system configuration and conditions of use. However, it is necessary to check that the pump suctions fluid and the pressure rises properly after the pump has been stopped for around a week to days. If suctioning at the pump cannot be confirmed, stop the pump and restart it by following the procedure above. D-

19 D GEAR PUMPS D GEAR PUMPS Handling Hydraulic oil Use a general-purpose hydraulic oil (R&O) equivalent to ISO VG to 68, or wear-resistant hydraulic oil. Operate the unit in an environment where both the following conditions are satisfied: viscosity range from to 4 mm /s {cst} and oil temperature from to 6 C. Contamination of the hydraulic fluid causes pump trouble and reduces the service life, so pay due attention to controlling contamination and ensure that it goes no higher than NAS contamination class 9. Filters Use a suction filter with meshes per inch at the inlet side. In the return line to the tank at the discharge side, use a line filter with a filtration accuracy of μm or better. Piping Ensure the suction port is airtight. Aeration will cause abnormal noise. When using steel pipes for piping, take care not to force the pump off center. Forcing the pump off center with pipes may cause abnormal noise. At start Supply fluid inside the pump before starting operation for better lubrication of sliding surfaces. After checking that all hydraulic circuits and electrical circuits are ready for operation, set the hydraulic circuit at the load side in the no-load status or connect an unloading circuit before starting the pump. Check that the pump rotates in the direction of the arrow showing the direction of rotation. When the pump is driven for the first time, turn the power switch to the motor on and off a few times to let the air out of the piping and then run it continuously at full speed. Noise may be observed until the air has been completely removed but this is not abnormal. At a fluid temperature of 7 C or lower, warm up the pump by running it at a pressure of MPa { kgf/cm } maximum and increase the pressure when the fluid temperature has risen. If there is a temperature difference of C or greater between the pump and fluid, warm up the pump to reduce the temperature difference to within C before running it. Suction pressure Maintain the suction pressure. kpa to kpa { mmhg to. kgf/cm }. The unit can permit a pressure up to 4. kpa { mmhg} for short time at the start but do not increase the pressure during this time. High suction pressures will generate cavitation and cause damage to the parts, noise, and vibration, resulting in a shorter pump service life. Rated pressure The rated pressure refers to the maximum pressure at which the product can be operated continuously. Maximum operating pressure The maximum operating pressure refers to the maximum pressure at which the product can be operated. D-
