I have a question about the item (Digi-Key Part Number:1890-1046-ND) which is a water pump. My question is to know if I can use it for air flow. If so, flow rate is still 2 L/min? Also can the flow rate be adjusted by changing the voltage?
Page 2 of the datasheet would suggest using air would not be feasible for the pump:
"
Rated Voltage: DC 12V
Load: Water
water absorption: 1L-1.2L/min
Current(With load): Less than 320mA
Flow : 2.0LPM
Total Size : D27 x 75mm
Water Hole Diameter: 6.5mm
Maximum pressure : More than 360mmHg
Noise:Less than <60dB
"
The specifications specifically say “water” as a load. The problem with air is volume can change despite the container that surrounds it while water has a set volume.
Please verify if one of below will work for you. The flow can be adjusted by changing voltage to some degree since it is just a DC motor. Click here for 1568-1344-ND | 1890-1035-ND
