Ring Pump RP-3S series
- The RP-3S series is a pump that achieves long life and large discharge rate by connecting three RP-S pump heads and driving it with a stepper motor.
- By consolidating the three IN into one and the three OUT into one, pulsation in the discharge flow can be further reduced compared to the RP-2S series, which has two dual pump heads.
(The IN and OUT are consolidated into a single line each for shipment.)
For more information on discharge flow pulsation, please see here.
- By suctioning different liquids into each of the three pump heads, three types of liquids can be delivered at the same time.

Stepper Motor Controller and Driver Board
RP-3S is driven by a stepper motor.
To operate a stepper motor, you need a controller or driver for that motor.
We offer the following dedicated controllers and driver boards as options sold separately. Please contact us if you need it.
Stepper Motor Controller
- You can control the motor by connecting to the motor with a lead wire.
- Using the buttons on the panel, you can control the rotation speed, rotation direction, start/stop of rotation, motor current settings, acceleration/deceleration time settings, etc.
- Motor speed setting, rotation direction setting, and start/stop of rotation can be controlled using external signals.
- DC24V 3A power supply is required. Please prepare a DC power supply, AC adapter, etc.
Stepper Motor Driver Board
- This is a driver board that connects the motor, power supply, and external control signals, and controls the motor using external control signals.
- Please prepare the equipment to send control signals by yourself.
- DC24V 3A power supply is required. Please prepare a DC power supply, AC adapter, etc.
