Raasm Series 120-AB 1/2″ 70 l/min Aluminium Diaphragm Pumps

These diaphragm pumps made of die-cast aluminium ensure lasting and reliable operation pumping a wide range of fluids, including high viscosities and containing suspended solids.  They can also be used for heavy applications in places with high humidity or a potentially explosive atmosphere due to being ATEX certified.


* With a PTFE membrane the flow rate is 10% lower

** Displacement per cycle may be influenced by suction lift, fluid viscosity, air pressure or number of cycles per minute

*** The materials in contact with the fluid can restrict the pump working temperature
