Raasm Series 120-PPAB 1/2″ 60 l/min Aluminium & Polypropylene Diaphragm Pumps

These diaphragm pumps made of die-cast aluminium and polypropylene manifolds ensure lasting and reliable operation pumping a wide range of fluids, including high viscosities and containing suspended solids.  In particular, these pumps can be used with corrosive and aqueous fluids with the seats being made from stainless steel AISI 316 and polypropylene.


* 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
