GRACO 24X427 – ChemSafe 307 Air Operated Double Diaphragm Plastic Pump w/ PTFE Seat, PTFE Ball,

GRACO 24X427 – ChemSafe 307 Air Operated Double Diaphragm Plastic Pump w/ PTFE Seat, PTFE Ball, Overmolded PTFE Diaphragm, PTFE Fluid Path & NPT Port, 100 PSI

ChemSafe 307 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.

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 7.9 gpm (30 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
