Graco Husky 2150 DFC311-Compatible 2″ Aluminum Air-Operated Diaphragm Pump, PTFE

This is a 2" 2150 Series air-operated double-diaphragm pump. With a flow rate of 568 liters per minute and a maximum operating pressure of 8.4 bar, it is used in high-volume transfer lines. The closed-center air valve is accessible from the outside; the pump can be serviced without being removed from the line. Since it can handle solid particles up to 6.3 mm in diameter, it operates without clogging in tank drainage and slurry lines. The aluminum liquid section, with its cost-effective housing, meets the needs of a wide range of general transfer applications. The PTFE diaphragm and ball maintain structural integrity when handling concentrated acids, ketones, aromatic solvents, and oxidizing chemicals. This configuration operates with a PTFE diaphragm at fluid temperatures up to 104 °C. It corresponds exactly to the DFC311 part number with the configuration number 2150A-A01AA2SSPTPTPT in the Graco® Husky 2150 series; it is manufactured with the same connection sizes and can be installed directly in place in an existing setup.
