RP-HⅡ Series : Pump head replacement type, Stepper motor drive

The RP-HⅡ is a stepper motor-driven pump with an interchangeable pump head.
The flow rate can be adjusted over a wide range from 0.2 to 200 mL/min, thanks to stepper motor control.
The pump head can be easily replaced using a one-touch magnetic coupling mechanism.
All pump heads (except the RK-HⅡ04R) are autoclavable:
• Autoclave: 121°C for 25 minutes, up to 10 cycles
Note: The RK-HⅡ04W model using "Transmaster TM-15"
tubing is not autoclavable.
• Gamma sterilization: 25 kGy
(Sterilization compatibility of "Versilon F-5500-A" tubing is unverified.)
Five tubing options are available to suit various applications.
An optional driver board for stepper motor control is available.

∗1. The maximum discharge volume is the discharge volume for one operation that can be set on the RE-C300. (The maximum number of rotations that can be set in one operation is 99 rotations.) ∗2. The first unit will be sold as a "Constant discharge pump system model No." that includes the pump and motor controller RE-C300.

The arrow indicates discharge direction
when the motor rotates clockwise.

Stepper Motor Driver Board

This series is driven by a stepper motor.
To operate the stepper motor, a dedicated driver board is required.
We offer the following driver board as a separately sold option. Please contact us if needed.
★ To use the driver board, you will need a pump equipped with wiring that includes
a JST connector compatible with the driver board (e.g., RP-HⅡ04*-200A-DC24VS).

Stepper Motor Driver Board BD202411-M

A driver board used to connect the motor and power supply, and to control the motor via external control signals.
Please prepare your own control device to send the control signals.
A DC 24V, 2A power supply is required. Please use a DC power source, such as a DC power supply unit or AC adapter.
