Feature

●Adjustment roller: the adjustment roller is used for adjustment, which is convenient for the user to replace the hose to avoid pinching and destroying the hose due to lack of experience of the user
●Step motor: the motor of the pump is a stepper motor with high control accuracy, low power consumption and stable performance
●Quick to disassemble: the pump lid can be screwed by hand to quickly disassemble it and simplify hose change
●Silent: the roller bearing adopts a quiet and durable wheel frame
