GRACO 24X421 - ChemSafe 1590 Air Operated Double Diaphragm Plastic Pump w/ NPT Port, 1/2", 100 PSI
ChemSafe 1590 Air Operated Double Diaphragm Pump with PTFE fluid path components for superior chemical compatibility. Features overmolded PTFE/EPDM diaphragms for enhanced durability and performance in demanding chemical transfer applications. 1-1/2 inch NPT connections provide high flow capacity up to 376 lpm (99.5 gpm).
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.
- Max flow rate of 85.2 gpm (322 lpm)
- High quality machined design provides a precision fit and superior chemical containment compared to molded pumps
- Corrosion-resistant exterior with no exposed metal reduces maintenance, extends pump life and offers clean, safe operation
- Removable air motor offers easy and intuitive maintenance ensuring maximum pump performance and availability
- Ideal for corrosive and abrasive liquids such as acids, fuels, glues, paints, resins, inks, or wastewater
