Griswold 811Griswold Pump has developed the 811 Series ANSI centrifugal pumps to perform reliably for a wide range of operations within the oil and gas industry. The company believes that the 811 Series ANSI pumps also offer:

  • An open-impeller design that minimizes concentrated wear by balancing the hydraulic thrust load and reducing stuffing-box pressure, which maximizes performance while simplifying maintenance, extending pump life and reducing repair costs.
  • A full range of sizes with flow rates up to 4,000 GPM (15,142 LPM) with the ability to operate in temperatures up to 500ºF (260ºC).
  • The ability to externally adjust the pump’s clearance so that peak efficiency is maintained.
  • Power frames that make the pumps an estimated 33 percent stronger than competitive models.
  • 2 times the wear area between the case and impeller when compared to closed-impeller designs.
  • The power to pump produced saltwater into trucks or pipelines, as well as facilitate the complete transfer of oil from a tanker to a storage tank.
  • Self-tightening impellers.
  • A casing constructed of ductile iron, CDM4Cu, Alloy 20 or stainless steel, while a no-bake casing process ensures smooth, precise finishes.
  • Operational flexibility, efficiency and durability.
  • Suitability for tank transfer and truck loading and unloading in low-temperature and low-pressure conditions.
