Graco Husky 1590 DBC666 Compatible 1.5″ Aluminum Air-Operated Diaphragm Pump, Santoprene

This is a 1.5" connection 1590 Series air-operated double-diaphragm pump. With a flow rate of 378.5 liters per minute and a maximum operating pressure of 8.4 bar, it is used in medium- to high-flow transfer lines. The closed-center air valve is accessible from the outside; the pump can be serviced without being removed from the line, and the epoxy-coated air section withstands harsh field conditions. It offers a 4.8 mm solid passage and a 6.1-meter dry suction lift. The aluminum liquid section meets the needs of a wide range of general transfer applications at an economical housing cost. The Santoprene diaphragm and ball provide fatigue resistance in fluids containing abrasive solids; a single elastomer type simplifies maintenance inventory. This configuration operates with a Santoprene diaphragm up to a fluid temperature of 82 °C. It corresponds exactly to the DBC666 part number with the 1590A-A01AA2SPSPSPPT configuration number in the Graco® Husky 1590 series; it is manufactured with the same connection dimensions and fits directly into the existing installation.
