S15 series miniature pump fluid is 3.2-6V wide voltage power supply and suitable for li-ion battery power supply. It has a small dimensions, long service life and working condition indicator. This models pump fulid can be gas or liquid or mixture of gas and liquids. It supports wide-voltage power supply technology and can work in the range of 3.2V-6V DC. When the voltage changes, the flow remains the same. Therefore, it is particularly suitable for scenarios where constant flow is required when battery power is used. For a lager flow rate, you  can also refer to S23  miniature liquid pump.

Compact Size

The product weighs about 50g and the overall size is about 50x29x36mm

 

Pump Fluid Liquid and Gas

Liquid and gas dual-purpose, can be used as a pump fluid or a vacuum pump, and can also be used to transport gas-liquid mixed medium; it can be dry-rotated and self-priming

 

Speed Control Feature

The flow can be changed by adjusting the motor speed of the pump (by adjusting the PWM duty cycle).

 

Allow Dry-Running

 

Brushless Motor

This model is driven by brush-less motors which have the advantages of long service life, low interference and high reliability. The premium version of this model product, after actual testing, has a continuous working life of more than 10,000 hours under maximum load, and a motor life of more than 20,000 hours.  It has extremely high reliability and service life.

Working Status Indication and Warning

The color of the indicator light displayed on the transparent bottom case (as shown in Figure 2-1 and Figure 2-2) can feedback the working status of the pump:

1. It is normal when the blue light flashes regularly;
2. When the light remainsred, it is abnormal, i.e.the motor runs too low;
3. When the red and blue lightsflash alternately, itis abnormal, and at this time,the motor speed is low and unstable;
4. The indicator light is offwhen the positive and negative connections are reversed;
5. When the voltage is outofthe working voltage range (3.2V～6V), the indicator light is off.

 

Protections

Equipped with overheating protection, overload protection and reverse connection protection function to prevent accidental damage to the pump.

 

Wide Voltage Supply

It can use 3.2V～6V wide voltage DC power supply, when the power supply fluctuates and changes within this range, the pump output flow remains unchanged, which is especially suitable for portable device with lithium battery power supply.
