Caution

1. The specified current consumption reflects normal operating conditions. Upon startup, an inrush current approximately three times greater than the normal value may be generated.

2. The minimum operating voltage may vary depending on tube size, material, operating environment, and other factors. Please verify performance under actual operating conditions.

3. A short circuit between terminals may occur due to motor end-of-life or between commutator slits under certain operating environments and conditions.To prevent circuit burnout or damage to the system, please implement appropriate protective measures, such as using fuses or other circuit protection devices.

1. The flow amount rotation is based on laboratory test at WELCO. This may vary depending on operating environment, lot tolerances, and other factors. Please veryfiy performance under actual operation conditions.
2. The reference flow rate of the pump is determined by the product of flow amount per rotation and motor speed.
