A diaphragm liquid pump is a type of positive displacement pump that operates through the motion of a flexible diaphragm within the pump chamber, making it suitable for handling an efficient diverse range of fluids in Industrial and Medical needs such as In-Vitro Diagnostics (IVD), Continuous Inkjet Printing (CIJ) or Fuel Cells. In order to fit the specific industry needs, Thomas offers a high level of customization.
Thomas's oil-less liquid diaphragm pumps are known for their durability and long-term compatibility. The broad Portfolio offers flow rates from 180 ml/min to 1,800 ml/min, operating pressures up to 4 bar, and suction heights up to 6 meters of water (18 in Hg). Additionally, the range also includes linear liquid pumps, providing cost-effective solutions with extended service life and minimal noise levels.
Thomas diaphragm liquid pumps provide high efficiency of operation along with continuous liquid flow with minimized pulses. Oil-less Thomas diaphragm liquid pumps deliver smooth, bubble-free transfer of media. Several fundamental aspects should be taken into account:
Liquid diaphragm pumps are the first choice for moving demanding fluids gently without any system downtime. Within the realm of industrial applications for these pumps, one can identify the following sectors:
Thomas Liquid diaphragm pumps are the preferred choice for handling demanding fluids smoothly without system downtime. Applications requiring high flow rates highly value these pumps for their reliability and flexibility. Their compact design saves space, and making them suitable for tight quarters.
In medical settings, their small size allows integration into portable devices like infusion pumps and diagnostic equipment. These pumps ensure precise and steady liquid flow, crucial for applications like drug delivery. In industrial applications, they perform remarkably well in tasks like chemical dosing and inkjet printing, owing to their sturdy build and compatibility with a wide range of fluids.
These pumps offer consistent fluid control, a vital feature for industrial processes such as chemical dosing, pharmaceuticals, and metering where precise control and accuracy are essential.
In these positive displacement pumps, the action of an eccentric on the motor shaft moves the diaphragm. During the down stroke, the pump chamber draws the medium in and expels it during the upstroke. Internal valves mounted within the pump head function as check valves and control the direction of flow.
