3456::8● Select pumps whose effective oil volume is larger than the total oil volumes required for the cylinder used. ● Normally, manual pumps are used horizontally. If they are used vertically (with the out- let port facing downward), select vertical types for the P-16B, P-1B, and P-4 series.● The cylinder speed is determined by the discharge volume and effective area of the pump. See the cylinder speed table on page 226. ● The operating valve attached to the pump differs between the single-acting and dou- ble-acting cylinders.● There are two types of high-pressure hoses: rubber hose and nylon hose. The weight, the minimum bend radius, etc. are different. See pages 176 to 178. ● The hose type is determined by the pump. Change the coupler of the cylinder if the couplers of the hose and the cylinder do not match. ● See the tables (on pages 176 to 178) that show correspondence of hoses, hose lengths, pumps, and cylinders. ● Couplers whose sizes correspond to different discharge volumes of pumps are avail- able. If the coupler size is incorrect, the predetermined cylinder speed may not be attained, and also noise and heat from the hydraulic oil could result. ● Securely and completely connect the couplers. Do not connect or separate the cou- plers while pressure is applied. ● A duster cap is included with a coupler. Be sure to use the cap after use. ● If the pressure fluctuates largely (e.g. punching), do not use S-1, S-2, nor ROC-13 cou- plers. ● Pressure gauges and switches, various types of joints, etc. are available. ● Select joints and high-pressure piping that correspond to the maximum operating pres- sure of the pump used. ● Special mounting brackets are required for Riken pressure gauges and switches. ● The cylinder speed must be within the following speed specifications. Otherwise, the equipment may be damaged or scattered matter may cause injury.During operation, the oil temperature must be within a range of 5 to 60 °C. If the oil temperature ex-ceeds the proper range, the equipment will be damaged and need repair (replacement of parts or thehydraulic fluid) at an early stage, resulting in poor performance. Use optional oil cooler(s) depending on condition of use.Under no load condition:500 mm/s max.30 mm/s max.Under no load condition:1000 mm/s max.50 mm/s max.At 70 MPaAt 70 MPaStandard typeStrong typecat-No.78E since2017Model SelectionPumpselectionHoseselectionCouplerselectionAccessoryselectionManual pumpsElectric PumpsSelecting a high-pressure rubber hose or nylon hoseCoupler selectionAccessory selection
