(Auto-return type)● The pumps can be changed to another type 1 model by changing parts, etc. (For type 1, see page 68.)■SMP-3012AR■SMP-30RK/SMP-40RK● The single-acting cylinder is operated by the remote controlled operating switch (SW-4WP).● Only while the PUSH button of the SW-4WP is pressed and held, the pumps stop automatically at the preset pressure for the pressure switch, maintain the pressure, and restart operation automatically. Only while the RETURN button is pressed and held, the solenoid valve operates to retract the cylinder.● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.)■SMP-3012RK■SMP-30NE/SMP-40NE● The single-acting cylinder is operated by the remote controlled operating switch (SW-4WP).● Non-inertial type pumps stop the cylinder when the push button is released while the cylinder is moving up or down under no load condition. The pumps can stop at the preset pressure for the pressure switch, maintain the pressure, and restart operation automatically (as long as the push button is pressed and held).● The pumps can be changed to another type 2 model by changing parts, etc. (For type 2, see page 68.)■SMP-3012NE■SMP-30NV/SMP-40NV● The single-acting cylinder is operated by the remote controlled operating switch (SW-4A).● The pressure cannot be maintained and the cylinder cannot be stopped halfway.● The pumps can be changed to another type 1 model by changing parts, etc. (For type 1, see page 68.)■SMP-3012NV■Hydraulic circuit diagram■Electric circuit diagramNo.79E since202571
