  • Technical parameters


Edwards’ D-LAB family of diaphragm pumps offers clean pumping capability in a lightweight and compact design, making them an ideal choice for many laboratory applications. These pumps can operate independently and require minimal maintenance. They are divided into 1-head and 2-head models, with pumping rates up to 2m3h-1.

D-LAB pumps are equipped with Teflon chemical resistant heads, diaphragms and Kalrez® valves making them highly valued especially in chemical and pharmaceutical laboratories. The 1-head pumps with a final pressure of 100 mbar are suitable for use with dryers or to replace water-jet pumps. 2-head pumps, which achieve a vacuum of 8 mbar, are used in evaporators, gas transfer and other medium vacuum applications.


• Completely lubricant-free, maintenance-free and quiet
• Modular design and 6 different pumping capacities – optimized for your specific application
• All parts of the pump in contact with gases are resistant to aggressive substances (PFTE, FFKM, PVDF)
