Peristaltinė pompa su 1,5-5V varikliu

Motor: micro 280 gear motor
Suitable for voltage between 1.5V-5V,
The motor supports PWM controll,
Can be adjusted to a very slow speed,
The peristaltic pump is mainly used for quantitative and precise control of flow,
You can change the direction of water in and out
And the pressure can reach relatively high pressure under small flow,
However, the water inlet and outlet of this pump should be blue pipe inlet,
The red tube effluent,
The red pipe joint is reinforced with a clamp,
Red is the high-pressure end of the effluent,
If you want to change the forward and reverse water outlet, it is recommended that the blue interface should also be reinforced with a clamp to prevent the water pipe from loosening under high pressure.
If the pressure is not too high, it is basically no problem.

The actual measured no-load speed and flow rate of the motor at different voltages are as follows,
If the PWM speed can be adjusted, a lower flow rate can be adjusted.

Voltage 1.5V, no-load current 0.35A, pump head speed 120 rpm, maximum flow 32mL/min.

Voltage 3V, no-load current 0.4A, pump head speed 265 rpm, maximum flow 70mL/min.

Voltage 5V, no-load current 0.45A, pump head speed 430 rpm, maximum flow 130mL/min.

The pump weighs about 66 grams.
