3 "R" Series Piston Pumps R / R-FR Instructions Instructions. Hydraulic Fluids Use petroleum base oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG- or. The recommended viscosity range is from to mm /s (9 to SSU) and temperature range is from to C ( to F), both of which have to be satisfied for the use of the above hydraulic oils.. Control of Contamination Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit. Please maintain the degree of contamination within NS Grade. The suction port must be equipped with at least a μm ( mesh) reservoir type filter and the return line must have a line filter of under μm.. Mounting When installing the pump the filling port should be positioned upwards.. lignment of Shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than. mm (. inches) TIR and maximum permissible misangular is less than... Suction Permissible suction pressure at inlet port of the pump is between - and + kpa ( in.hg Vacuum and 7 PSIG). For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used. Make sure that the height of the pump suction port is within one metre (. ft) from the oil level in the reservoir.. Hints on Piping When using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise. Whenever there is fear of excessive load, please use rubber hoses. 7. Suction Piping In case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line.. Drain Piping Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than. MPa (. PSI) and surge pressure of less than. MPa (7. PSI). Length of piping should be less than m (. ft.), and the pipe end should be submerged in oil. In case R and R pump, a screw-in torque of fitting is to Nm ( to IN.bs.). Do not apply bending and thrust torque to the fitting.

81 Variable Displacement-Double Pumps Compensator Type Instructions / Performance Characteristics Instructions When using at a higher pressure than the rated pressure Care should be taken in cases of used at a higher pressure than the rated pressure, because operating terms may be restricted. For example, if used as per maximum illustrated operating conditions, intermittent time at maximum flow is restricted to under / of one cycle time and under seconds simultaneously. Conditions may vary according to the actual working pressure and delivery (inclination angle of the swash plate). Consult factory or Yuken sales representative for further information. llowable With the pumps listed in the table below, there is a limit to the sum of the input power of the inboard and outboard pumps because of shaft strength.

104 "H" Series Piston Pumps Instructions Instructions. Hydraulic Fluids Use petroleum base oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG- or. The recommended viscosity range is from to mm /s (9 to SSU) and temperature range is from to C ( to F), both of which have to be satisfied for the use of the above hydraulic oils.. Control of Contamination Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit. Please maintain the degree of contamination within NS Grade. The suction port must be equipped with at least a μm ( mesh) reservoir type filter and the return line must have a line filter of under μm.. Mounting When installing the pump the filling port should be positioned upwards.. lignment of Shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than. mm (.9 inches) TIR and maximum permissible misangular is less than... Suction Permissible suction pressure at suction port of the pump is between -.7 and + kpa ( in.hg Vacuum and 7 PSIG). In case of the speed is over r/min, adjust the pressure to + kpa ( to 7 PSIG). For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used. Make sure that the height of the pump suction port is whithin one metre (.ft.) from the oil level in the reservoir.. Hints on Piping When using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise. Whenever there is fear of excessive load, please use rubber hoses.. Drain Piping Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than. MPa ( PSI) and surge pressure of less than. MPa (7 PSI). Length of piping should be less than m (. ft.), and the pipe end should be submerged in oil.

Inside Dia. of pipe mm (.7 in.) 9 mm (.7 in.) 9. Bleeding ir It may be necessary to bleed air from pump case and outlet line to remove causes of vibration. n air bleed valve (Model No. ST- -, Catalogue No.: Pub. EC- ) is recommended for this purpose.. Starting Before first staring, fill pump case with clean operating oil via the fill port. In order to avoid air blockage when first starting, adjust the control valves so that the discharged oil from the pump is returned direct to the tank or the actuator moves in a free load. [Volume of Pre-fill Oil Required] 7. Suction Piping In case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line. No.
