Diaphragm liquid pumps – things to consider

Which criteria are important for choosing a diaphragm liquid pump? An important aspect is the versatility and long maintenance-free life. Diaphragm liquid pumps are suitable for transferring a wide range of fluids. Also aspiration of fluids is a frequent operation mode for diaphragm liquid pumps. The third use case is pumping fluids against high system pressure. Therefore diaphragm liquid pumps are remarkably robust and offer long-term compatibility with superior resistance to chemical or mechanical stress.


Diaphragm liquid pump are the choice for moving demanding fluids gently without any system downtime.

Many high tech devices in various industries rely on diaphragm liquid pumps for controlling the movement of fluids in order to ensure maximum efficiency, reliability and accuracy of the device.

This is the reason why market leading device manufacturers in many industries choose Thomas diaphragm liquid pumps. Our extensive R&D efforts and innovations have made us one of the leading suppliers of diaphragm liquid pumps.
