(.). (.9). (.).9 (.). (.). (.) 9. (.) (.). Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent 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 six 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.. The table above shows specifications for using petroleum based oils. Pumps (customized design) for special fluids are also available. Their operating pressure and maximum shaft speed however differ from the values in the table above depending on the fluid type. Range of operating temperature and viscosities may differ from those of petroleum based oils due to their characteristics. Minimum Operating Presure Shaft Speed Range Adj.

In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of the flanges. Therefore, please pay cautious attention to the operating pressure when the socket welding flanges are used.. As dimensions of the pipe flange mounting surface are conformed to SAE Bolt Split Flange (Standard Series), pipe flanges conforming to the SAE Standards can be used. Single Pump, Compensator
