ChemSafe 1040 Air-Operated Double Diaphragm Pumps

ChemSafe 1040 Air-Operated Double Diaphragm Pumps

Graco’s ChemSafe pumps feature PTFE or UHMWPE (ultra high molecular weight polyethylene) corrosion-resistant fluid paths, which make them ideal for corrosive and abrasive chemicals. There’s no exposed metals and they can be configured in various materials to meet most abrasion, temperature, and chemical compatibility requirements. Plus they’re dead-head capable and achieve high flow rates while minimizing air consumption and operational noise.
