Working Principle

The micro diaphragm liquid pump drives the reciprocating motion of the diaphragm through the motor to achieve the suction and discharge of liquid. The motor drives the diaphragm up and down through the eccentric wheel or gear. When the diaphragm moves upward, the liquid is sucked into the pump chamber; when it moves downward, the liquid is compressed and discharged. The diaphragm is completely isolated from the liquid channel to prevent the liquid from contacting other parts of the pump, ensuring the purity of the liquid and the precise control of the flow rate.

Micro Diaphragm Liquid Pump Advantages

TOPSFLO diaphragm liquid pump TF series has the characteristics of compact structure, low noise, extreme chemical resistance and easy operation, and is widely used in printer, madical, chemistry, food and other fields.

Compact 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.
Extreme Chemical Resistance

The use of chemically resistant materials optional such as PTFE FKM or other ，material combinations for the parts which allows the corrosive gas to be pumped.
Long Lifespan

Imported high-precision molds and raw materials, and high-grade coreless brushless DC motor, which has a longer lifetime and can be used for a long time. More reliable, and maintenance free

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.
Pneumatic Connectors

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