Ring Pump RP-QⅡB/C & RP-QⅢB/C series (Stepper motor drive)

RP-QIIB/C, QIIIB/C Photo
  • A stepper motor drive has been added to the QⅡ/QⅢ series, which are popular for their small size and interchangeable heads. It is possible to handle minute discharge volumes.
  • RP-QⅢ series has useful mounting holes.
  • [QⅡB, QⅡC and QⅡF] or [QⅢB, QⅢC and QⅢF] models have different drive motors, but their appearance and dimensions are the same.
  • A dedicated motor controller is sold separately.
    (RE-C200/C201,  RE-C500/C501,  RE-C600,  RE-C602 )

  • Pump head replacement is a one-time disposable.
  • Models with silicone tubes can be autoclaved at 121°C for 25 minutes, 1 time.
  • All of the standard models below are capable of gamma sterilization with 25 kGy.

∗1. The difference between RP-QⅡxxxx and RP-QⅢxxxx is the presence or absence of holes
to fix the pump. If the xxxx part is the same, other specifications are the same.
(See outline drawing below)
∗2. The pump with a connector is required for use with the motor controller RE-C500/C501.
∗2. The pump without connectors can be used with RE-C200/C201.
∗2. RE-C600 can be used with or without connector.
∗3. The RP-QⅡF and QⅢF series can only be used with the dedicated motor controller
RE-C602.
∗4. The discharge rate is the value when using the motor controller RE-C600/C602 and driving
at 1 to 1,000 PPS.
