12V vacuum pump application: beauty industry, gas detection, laboratory experiment, inhalation, industrial automation, product DIY parts, etc..
HLVP6 12V vacuum pump high flow rate, low noise, with rubber shock absorber, effective shock absorption. Using high-performance long-life brushless motor, stable performance and durable..
HLVP6 series diaphragm vacuum pumps are simply designed according to the design principles of positive displacement pumps. It is mainly suitable for occasions with high requirements for noise and vibration (medical equipment, beauty and health care, laboratory gas analysis equipment, etc.). The core characteristics of the product are low noise, low vibration and long life..
This series of products has a larger compression chamber, which enables the product to obtain high flow under the condition of low compression. Thanks to the two core noise reduction technologies (1. Noise reduction technology in the pump.
2. Rubber vibration reduction technology), coupled with a precise balance design, the pump's working noise is effectively reduced..

Malfunction and solution:The flow meter is not accurate. 1. The method of field calibration is not correct. Calibrate again. 2. The flow rate on the meter is below the lowest. Increase the flow rate. 3. The flow meter is blocked by the dry liquid. Take out the impeller and clean it carefully and make sure the impeller turns freely..
4. The impeller is wrapped by the sealing material. Remove the meter and make sure the impeller turns freely. 5. Too close to the impeller. Install properly 6. Too close to the motor or electronic noise environment.
The meter can not calibrate. 1. Circuit board is break down. Replace the circuit board. 2. Button is fail to press. Replace the circuit board..

FLOW METER: Before use, please calibrate the flow meter with the liquid to be tested. And the flow rate of the liquid should exceed 2.5 gallons per minute, if the flow rate is too slow, the flow meter cannot measure normally. There is no battery included..
MULTI-FUNCTION DISPLAY: High-definition LCD display, can read single cumulative flow, instantaneous flow and total cumulative flow. The clear function can clear the value of cumulative flow, to make sure it is always within the measuring range. If your flow meter cannot work, please contact us in time..
HIGH-QUALITY MATERIALS: The aluminum alloy housing is sturdy, durable and corrosion-resistant, which have a long service time. The PCB circuit board make the battery have a long service life, and safe in use. Please NOTE: the LCD display is not water proof.
INSTALLATION: The flowmeter can be installed in horizontal and vertical directions, but the flow direction of the liquid needs to be consistent with the direction of the arrow on the flowmeter. There is no direction requirements for the installation of the display screen..
MEASURABLE LIQUIDS: The turbine flow meter can used for measuring the water, gasoline, diesel, kerosene, methanol and other low-corrosive, non-viscosity liquids..
