Thank you very much for your continued patronage.
Our company will be closed on the following dates during the year-end and New Year holidays.
【Closure period】 December 28th (Sat), 2024 - January 5th (Sun), 2025
Please note that all inquiries received via email or fax during this closure period will be sequentially responded to from January 6th (Mon), 2025 onwards.
We apologize for any inconvenience this may cause and appreciate your understanding.

• New models using FKM-70 (fluororubber) tube that can be used with special solvents
• New models using TM-50 (olefin-based) tubes with low sorption properties, suitable for
  cell culture applications.
• New models in the RP-QⅡF/QⅢF series that use small-diameter tubes ideal for constant-volume
  dispensing of several tens of μL

• This is an ultra-low power consumption pinch valve. It can be operated with two AA
   batteries (3V). Therefore, almost no heat is generated.
• Compact and lightweight design with dimensions of 30 x 23 x 41.5 mm and weight of
    approximately 33 g.
• The cover is attached and detached with a magnet, making it easy to replace the tube.

The Kansai Bureau of Economy, Trade and Industry has created and published "The Kansai
Companies Profile", a catalog designed to promote Kansai's attractive mid-sized and small
companies to overseas missions and companies, fostering new business opportunities.
We are pleased to announce that our company information has been included in this catalog.

Comparison data on tube inner wall wear particles between our Ring Pump and other
manufacturer's roller pump is now available for download. (It is our experimental data)

• The discharge rates range from 2.6 to 2,600 μL/min.
• The appearance and size are the same as the existing RP-QⅡB/QⅢB and QⅡC/QⅢC models.
• Due to the change in motors, we are also launching the dedicated motor controller RE-C602
   simultaneously.

• Ring pump with a discharge rate of 9 - 2,500 mL/min using a stepper motor.
• Because 3 pump heads are connected, pulsation of discharge flow can be reduced.
• Three types of liquids can be delivered at the same time by using separate tubes.

• Pump drive motors can be selected from a brushed DC motor, a brushless DC motor, and
  a stepper motors.
• Pumps using a brushless DC motor and a stepper motor are equipped with a needle roller
  bearing. Therefore they achieved 5,000 hours of continuous operation. (Our experimental value
  using water. Life expectancy is not guaranteed.)
• You can choose from 6 types of tubes depending on your application.

 • Stepper motor controller for 1 piece of RP-TX, HX, RP-QⅡB/C, and RP-QⅢB/C series
 • Various pump operation can be controlled by a computer connected to RE-C600.
 • The pump can be stopped at specified number of revolutions, supporting fixed discharge.

The model using a stepper motor has been added to the popular micro pump RP-QⅡ/QⅢ series.
It is possible to control the discharge rate more finely than ever before.

 • Stepper motor controller for RP-HX, RP-TX, RP-QⅡB/C, RP-QⅢB/C series
 • Various pump operation can be controlled by a computer connected to RE-C500.
 • RE-C500 can control 6 pumps individually.
    Furthermore, up to 12 pumps can be controlled by adding one RE-C501.

 • A constant discharge pump system is realized by the pump using a DC motor with an encoder
    and the motor controller RE-C300 that accurately stops the rotation of the motor at an integral
    multiple of one rotation.
 • We offer the following 4 series of pumps.
RP-H···DC24VE, RP-HⅡ···DC24VE, RP-M···DC24VE, RP-KⅡ···D24VE
