Griswold’s 811 Series ANSI Centrifugal Pumps are ideal for a broad range of applications in the demanding liquid-terminal industry because they utilise self-tightening impellers that reduce leaks and failures. The 811 Series features the ability to externally adjust the clearance, ensuring peak efficiency even after wear-loss; back pump-out vanes that reduce pressure on the shaft seal and bearings; and investment-cast impellers that are ultra-smooth to guarantee hydraulic and mechanical balance, and maximised seal and bearing life.
The 811 Series offers a full range of pump sizes, as well as options and upgrades that can be tailored to meet virtually any liquid-terminal application with flow rates up to 1590 m³/h. Among the 811’s features are the availability of standard and low-flow models, heavy-duty power frames, fully open impellers with rear adjustment capability, and a wide variety of mechanical-seal options. 811 Series pumps are available with ductile iron, 316 stainless steel, CD4MCu and Alloy 20 liquid paths, which make them viable in temperatures as high as 260 °C.
