Product Features

Optimized pump body to ensure small volume, provide large flow and maintain relatively low power consumption. The gas flow is stable and the motor runs in a wide range.

- High performance

- Dc brushed motor with 2000hours lifetime

- Dc brushless motor with >10000hours

- Imported ball bearing material design

- Professional seal design ensures low leakage rate

- Pollution-free sample gas

- High quality imported EPDM and PTFE/FKM

- Rubber materials, withstand a variety of gas corrosion

Common issues include leakage (seal failure), motor burnout (overvoltage/overload), clogging (debris in fluid), excessive noise/vibration (wear, air bubbles, misalignment), and reduced flow/pressure (impeller damage, voltage drop). Prompt maintenance, correct voltage, and clean fluids prevent most failures.
