Working Principle

The micro diaphragm gas pump drives the reciprocating motion of the diaphragm through the motor, and uses the bending and stretching principle of the diaphragm to achieve gas inhalation and exhaust. The motor drives the eccentric wheel or gear to move the diaphragm up and down. When the diaphragm moves upward, the gas in the pump chamber is inhaled; when the diaphragm moves downward, the gas is compressed and discharged. The diaphragm of the pump is completely isolated from the gas channel, avoiding contact between the gas and the motor components, thereby ensuring the purity of the gas.

Micro Diaphragm Gas Pump Advantages

TOPSFLO diaphragm gas pumps are compact size, low-noise, and high-efficiency, and are widely used in medical, laboratory, and gas transfer fields.

Small Size & High Performance

Innovative and efficient engineering design, lightweight and compact size, which takes up almost no space in your laboratory. With relatively higher performance and efficiency, which allows a wide field of applications to be covered.
Low Noise & Little Vibration

Optimized head, chamber, and flow path to ensure long-term quiet operation of the pump. The noise level is as low as 50dB, which is 5-10dB lower than the other diaphragm pump with same parameters. Lower noise and less vibration.

Options We Can Offer

Motor driven

DC motor provides driving force for pump head operation. The diaphragm seals the compression chamber off from the drive mechanism with nearly zero leakage.
Elastomers

Elastomers of different materials can meet the transmission requirements of different media, especially corrosion-resistant materials can achieve a longer working life.
Control Signals

Most product models support speed adjustment signals and start-stop control signals, which makes it easier to control flow and on-off. These signal specifications can be customized.
Flow Rates

In addition to changing the flow rate by adjusting the speed through the signal, the flow rate of the pump can also be customized through different eccentrics and changing the volume of the pump cavity.
Pressure

According to the demand, it can be realized by changing the motor speed and pump chamber size
Pneumatic Connectors

For different piping systems, different connectors such as hose connectors with different size, push-in connectors, internal thread connectors can be selected
