Welch corrosion-resistant diaphragm pumps are driven by explosion proof motor. The aluminum pump head is PTFE coated and the diaphragm is covered by a PTFE liner to separate chemical media from the diaphragm. The explosion proof motor is directly coupled to the diaphragm pumping module. Stainless steel tubing is used to connect pump heads together in one and two-stage configurations.

Chemical resistant, vacuum bleed valve regulator with dial vacuum gauge to vary vacuum level to maximum vacuum of pump. (Cat. No. 2090K-05)

Important: Always use a certified electrician for proper installation of pumps with explosion proof motors. Conduit wiring required. No cord, plug, or switch included.
