- NEW Product information;
Large discharge rate by 3 pump heads; RP-3S series -
• 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.

- NEW Product information;
Pump head replacement type, capable of discharge rate up to 10 mL/min; RP-H series -
• 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.

NEW Product information;
Constant discharge pump system; RE-C300-H/HⅡ/M/KⅡ -
• 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
