Graco Husky 1050 647109 Compatible 1″ Aluminum Air-Operated Diaphragm Pump, PTFE

This is a 1" 1050 Series air-operated double-diaphragm pump. With a flow rate of 189 liters per minute and a maximum operating pressure of 8.6 bar, it is used in high-pressure applications involving medium-volume transfer lines. The non-stuttering, low-pulsation air valve changes direction without stalling during sudden load changes; the one-piece center section minimizes leakage points. With a 3.2 mm solid passage, it offers a dry suction depth of 4.9 meters and a wet suction depth of 8.8 meters. The aluminum fluid section meets the needs of a wide range of general transfer applications at an economical housing cost. The PTFE diaphragm and ball maintain structural integrity when handling concentrated acids, ketones, aromatic solvents, and oxidizing chemicals. It corresponds exactly to part number 647109 of the Graco® Husky 1050 series with configuration number 1050A-A01AA2SSPTPTPT; it is manufactured with the same connection dimensions and can be installed directly in place in an existing setup.
