Features of RD series

Compact and lightweight with a seal-less structure

The canned motor type products in our RD series are light and compact. Unlike conventional magnetic drive pumps, they do not require a large amount of space for installation. Their seal-less structure eliminates leaks and problems involving seal replacement.

Long life

A DC brushless motor is employed as the pump drive. This type of motor reduces concerns over brush abrasion, ensuring a service life as long as that of an AC motor.

Facilitating standard compliance

The RD series pumps power source voltage is classified as safety voltage (50 V or less), which allow the user to easily comply with international standards such as UL, CSA, CE and GS.

Flow rate adjustment

Flow rate can be adjusted by means of an external signal of 1-5VDC.
