If the pressure drops a few MPa below the preset one, the pump will restart operation automatically.● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.)■SMP-3012SPliHydraucPumpscat-No.78E since2017 ■SW-4WP ■SW-4WP ■SW-4WP■SMP-30SL・SMP-40SL● A double-acting cylinder, torque wrench, etc. are operated by the remote controlled operating switch (SW-4WP).● Only while the PUSH button of the SW-4WP is pressed and held, oil is discharged from port B, and the pump automatically stops at the preset pressure for the pressure switch, maintaining the pressure. Only while the PULL button is pressed and held, oil is dis- charged from port A. As soon as the button is released, the outlet port is switched to B, and the amount of oil for the inertia of the motor is discharged from port B.● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.) ■SMP-3012SL■SMP-30SW・SMP-40SW● The remote controlled operating switch (SW-4WP) operates a double-acting cylinder.● Because of its good responsiveness, the pump can stop the cylinder immediately. Even if the button of the SW-4WP is released, pressure can be maintained for a long time due to the check valve. ● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.) ■SMP-3012SW ■Hydraulic circuit diagram ■Hydraulic circuit diagram ■Hydraulic circuit diagramABABAB liOlKD-3CSPS-7A1.5MPaKD-3S(a)KD-3S(b)KD-2S1.5MPaKD-3C(a)KD-3C(b)SPS-7A1.5MPa73MPa73MPa73MPa ■Electric circuit diagram ■Electric circuit diagram ■Electric circuit diagramSMP SeriesSmall-Size Portable Electric Pumps for Double-Acting Cylinders (SMP Series)SPS-7A74
