tt l li■SMP-30C/SMP-40C● A double-acting cylinder is operated by the direction-control valve (SMV-43) and the remote controlled operating switch (SW-4A), which are attached to the pump.● At the preset pressure for the pressure switch, the pump can stop automatically and maintain the pressure. If the pressure drops a few MPa below the preset pressure, it will restart operation automatically.● During the transition period of switching the switching handle, all ports are open and pressure drops.● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.) ■SMP-3012CspmuPspmuP yre launaMaBseireSPMSspmuP cirtceEspmuPacepS■SW-4AreooCilspmuPcuardyHcat-No.78E since2017■SW-4A■SW-4A■Hydraulic circuit diagram■Hydraulic circuit diagram■Hydraulic circuit diagramABAB lilOABSPS-7ASMV-4373MPa1.5MPaSMV-43KRV-3410 to 70 MPa73MPa1.5MPaSCB-43BSPS-7A1.5MPa17.5MPa73MPa■Electric circuit diagram■Electric circuit diagram■Electric circuit diagramSMP SeriesSmall-Size Portable Electric Pumps for Double-Acting Cylinders (SMP Series)73■SMP-30CR/SMP-40CR● A double-acting cylinder is operated by the direction-control valve (SMV-43) and the remote controlled operating switch (SW-4A), which are attached to the pump.● Pressure can be adjusted by the relief valve attached to the pump and maintained . (Pressure adjustable range: 10 to 70 MPa) The hydraulic oil temperature range is 5 to 60 °C. If the relief valve is operated for a long time, pay attention to the rise in oil temperature.● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.)■SMP-3012CR■SMP-30DCB/SMP-40DCB● A double-acting cylinder is operated by the direction-control valve (SCB-43B) and the remote controlled operating switch (SW-4A), which are attached to the pump.● The SCB-43B incorporates a pilot check valve and an external pilot-operated counterbalance valve to prevent heavy load from falling by its own weight while the pump is jacking up the load. (The falling-by-self-weight prevention circuit is provided to port B only.)● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.)■SMP-3012DCB
