The Graco Husky 205 D11026 is a compact air operated double diaphragm pump designed for low-flow industrial transfer, dosing, sampling, and process-fluid applications. This model uses an acetal fluid section with stainless steel fibers, acetal check valves, and Santoprene diaphragms.
The D11026 delivers a maximum flow rate of 18.9 L/min and operates at fluid pressures up to 7 bar. Its pneumatic 1:1 design allows flow to be adjusted through the air supply, making it suitable for applications where smooth control and reliable low-volume transfer are required.
This pump features 1/4 in. female NPT fluid ports, a 1/4 in. NPT air inlet, and a 1/4 in. NPT exhaust connection. The compact construction and 1.1 kg pump weight support installation in laboratory systems, chemical dosing skids, wash systems, small manufacturing equipment, and general industrial fluid-transfer lines.
The spring-loaded check valve design improves priming performance and helps the pump operate reliably in different mounting orientations. Before use, verify fluid compatibility with acetal, Santoprene, PTFE, and stainless-steel-containing wetted materials.
