ChemSafe pumps are equipped with corrosion-resistant PTFE or UHMWPE (ultra high molecular weight polyethylene) fluid passages making them ideal for corrosive and abrasive chemicals. The pumps are free of exposed metal and can be assembled using a variety of materials to meet basic requirements in terms of abrasion, temperature, and chemical compatibility. In addition, the pumps are equipped with an outlet blocking function and achieve high flow rates while reducing air consumption and operating noise.
