*1. The consumption current described above is the value during normal operations.
An approximately threefold inrush current occurs during rotation startup.

*2. Measurement conditions for the pump noise level conform to JIS B 8310: 1985.

*3. The values indicated for durable service life are not guaranteed. The data shown is the result of tests performed by flowing distilled water under the conditions of 20℃ room temperature, and intermittent switched operation of 60 seconds ON and 15 seconds OFF. The results vary depending on the chemicals used, ambient temperature and humidity, and operating cycle conditions. Use the indicated values as guidelines.

*1. Above data is measured under 100mNm dummy load added condition.
Depends on tube material assembled in pump, torque load will change, influences to motor rpm.
And the temperature of the motor affects to motor rpm also.

*2. Minimum operating voltage may change by tube material, size and ambient temperature.

*3. Short circuit between terminals may occur due to end of motor life or short circuit between commutator slits by specific operating environment and condition. In order to prevent circuit burnout, please take protective measures such as using fuses.

*4. The lowest operation voltage may vary depending on the tube type, tube size, ambient temperature, etc.
Please contact your sales representative to get help when you operate by lower voltage.

Please consider these points, we recommend to test enough under your own condition.
