Engineered to withstand severe conditions in food process and general applications, Griswold’s 811 Series ANSI pumps have heavy-duty power frames. A fusion-bonded epoxy coating on the interior surface of the frame provides a barrier between the iron frame and oil to enhance the quality and cleanliness of the lubricating oil. The pumps come in standard and low-flow models with fully open impellers with rear adjustment capability and a variety of mechanical-seal options. The pumps are available with ductile iron, 316 stainless steel, CD4MCu and Alloy 20 liquid paths that make the pumps viable in temperatures up to 500
