Putzmeister Esser 900 5" (125mm) Big Mouth Boom Pipe

Putzmeister’s premier boom pipe offering, Esser 900 pipe has the longest service life on the market and is ideal for high-volume pumping under extreme wear conditions. This ultra wear-resistant pipe is made of a static outer pipe with an inner pipe with heat-treated hardness up to 67 HRc. It is fitted with two patented twin-cast Big Mouth flanges to prevent the radical transfer of destructive wear from the elbow to the straight pipe. A unique welding process results in no heat-affected areas of the pipeline.
