Self-Priming Pump 360 Motor Gear Jet Oil Mini Pump DC 3V 6V 12V

Brand new original 360 (motor) gear pump,

It can self-priming, powerful power,

It was originally designed to use the US (Swiffer Wet Jet) spray cleaning mop water pump,

The characteristic of the gear pump is that the flow rate is not large,

However, the water pressure is high.

The rare thing is that these pumps are brand new,

It’s still the original, not many,

Don’t miss your favorite friends.

The plastic jacket at the water inlet can be removed,

Inside is a steel needle tube,

The normal wiring method of this pump:

The terminal with red dot is connected to the positive pole of the power supply,

The terminal without red dot is connected to the negative pole of the power supply,

Then, the wiring is such that the side with the needle is the water inlet,

The side nozzle is the water outlet.

But the gear pump has a characteristic,

The motor can be reversed,

Is to connect the terminal with red dot to the negative pole of the power supply,

The terminal without red dot is connected to the positive pole of the power supply,

This will turn the motor in reverse,

At the same time, the functions of the inlet and outlet are switched over,

The original water inlet becomes the water outlet (the end with the needle),

The original water outlet becomes the water inlet (the side pipe mouth).

And the traffic after reverse connection has increased exponentially and become more powerful,

So if it is DIY,

We suggest that the reverse connection works better,

Of course, the working current of the motor is much larger.

Now test the parameters of the water pump according to the regular wiring method:

Voltage: DC6V current: 2.7 A

Voltage: DC12V current: 3.7 A (only suitable for short-time work)

Power on test machine,

Pumping flow at DC6V is ok,

The flow and pressure of pumping are better at DC12V,

But the current is too large,

Although the current shown is 3.7A,

But the power supply of 5A is lit red,

The motor is too easy to heat,

Only suitable for short hours.

So if it is DIY,

We also recommend that the positive and negative poles of the motor be connected in reverse.

But the reverse connection is not recommended for DC12V,

Because the pumping current reaches 4.2 A at DC6V,

But the flow and pressure are more powerful,

The effect is much stronger than the regular wiring method.

Pump weight: 72.5 grams
