Ring Pump RP-H series : Pump head replacement type,
DC motor/Brushless DC motor drive

Pump head replacement type capable of discharging up to 10mL/min.
Pump head replacement is a one-touch method using strong magnets.
The standard model is compatible with three types of motors: brushed DC motors, brushless DC motors, and stepper motors.
The pump uses a brushless DC motor and a stepper motor achieved 5,000 hours^∗1 of continuous operation by using needle roller bearings.
(∗1: It is our experimental values using water, and do not guarantee the pump lifespan.)
All pump heads (except RK-H1.6R) are sterilizable:
• Autoclave (25 minutes at 121℃) 10 times is possible.
Note: The RK-H1.6W model using "Transmaster TM-15"
tubing is not autoclavable.
• Gamma ray sterilization (25kGy) is possible.

(Sterilization compatibility of Versilon F-5500-A tubing is unverified.)

Versions with a Stepper motor are also available.

∗2. The brushless DC motor have a built-in driver board. The pump also comes with a 500mm long wire with a connector for connecting to the driver board. ∗4. Some of Saint-Gobain's tube names are changed a few years ago. Versilon F-5500-A ← Fluran F-5500-A (Old name)

Models using the DC brush motor

*Install with the motor shaft horizontal.

Discharge direction when the positive side of DC
power is connected to the terminal with the + mark
and the negative side is connected to the terminal
on the opposite side.

Models using the DC brushless motor

*Install with the motor shaft horizontal.

Discharge direction
when the rotation direction is CW.

Driver board for brushless DC motor

The brushless DC motor used in the RP-H series has the built-in driver board.
The driver has the following functions: speed control, rotation direction switching, braking, and rotation signal output of 180 pulses per pump revolution.^∗4
The pump is supplied with wiring with connectors for external connections.
The driver input/output details are as follows.

∗4 & 5 : Since the motor outputs 6 pulses per revolution and the reduction gear ratio

is 1/30, the number of pulses per revolution of the pump is 6 x 30 = 180.
