Double Diaphragm Pumps
Configure your air or electric fluid pump to handle abrasive and corrosive materials
Graco’s diaphragm pumps are designed for industrial and chemical transfer applications. Our chemical and industrial diaphragm pumps come in pneumatic and electric options, with many flow rates and sizes. Both metal and plastic housings can easily handle corrosive and abrasive fluids. All of our industrial diaphragm pumps are thoroughly tested before they leave our factories.

Chemsafe 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 minimising air consumption and operational noise.
Available with BSPT or NPT ports in variants:
| Model | Size | Flowrate |
| Chemsafe 205 | 6.3mm | 14 L/min |
| Chemsafe 307 | 9.5mm | 30 L / min |
| Chemsafe 515 | 12.7mm | 63 L / min |
| Chemsafe 1040 | 25.4mm | 142 L / min |
| Chemsake 1590 | 38.1mm | 322 L / min |

Husky Air Pumps
The difference from an air-operated diaphragm pump is the centre section of this pump as it uses an electric drive instead of compressed air. The centre section of this pump is filled with pressurised air and is mechanically moved left/right by the motor so it pushes and pulls the diaphragm from left to right.
