Griswold Pump Co.: 811 Series (ANSI) centrifugal pumps

By |  February 18, 2013

Griswold Pump Co.’s 811 Series American National Standards Institute (ANSI) centrifugal pumps are ideal for tank transfer and truck loading and unloading in low-temperature and low-pressure conditions. They have two times the wear area between the case and impeller when compared to closed-impeller designs, the company says. The 811’s open-impeller design also minimizes concentrated wear by balancing the hydraulic thrust load and reducing stuffing-box pressure. The pumps are available in a full range of sizes with flow rates up to 4,000 gpm, with the ability to operate in temperatures up to 500º F.
