By design, Thomas diaphragm pumps provide significant benefits to the end-user.
The diaphragm pump platform can be extensively customized to meet rigorous application and project requirements. Depending on the model series selected, different pump configurations, motors and elastomer materials are available.
Our gas diaphragm pumps and compressors are designed to consistently meet customer specifications and performance requirements. Whether the task is to transfer air or gas from A to B or to meet a precise working point, diaphragm technology is a highly efficient and reliable way of getting the job done.
Thanks to the reliable performance, compact size, and efficient operation Thomas gas diaphragm pumps are the first choice for medical and environmental industries amongst others.
Especially mission-critical and portable devices like gas analysis rely on our products. Application know-how and years of experience allow our Engineering teams to customize your pump to the most demanding conditions.
Gas diaphragm pumps are reciprocating pumps. An eccentric transforms the motor’s rotational movement into an up and downward motion of a con-rod. Attached to the con-rod is a flexible diaphragm. The linear movement of the con-rod causes the diaphragm to sweep through a clearance volume within the pump head. On the down-stroke air or gas is drawn into the pump head assembly. On the up-stroke the media is pushed back out.
