In general, the Binks Gemini II diaphragm pump series is the successor of the well-known Gemini product line.  The new 1/2″ acetal diaphragm pump (41-818836) replaces the 1/2″ acetal diaphragm pump (818831) and delivers up to 33% more fluid per stroke than the previous model. The body of the pump is made of conductive acetal, therefore absolute non-corrosive and groundable. The diaphragm is made of PTFE to withstand even very abrasive fluids.


wide range of paints, dyes, stains, glazes and lacquers, including abrasive fluids and coatings.
