Griswold 811 Series Pumps help oil-and-gas producers maximize productionMarch 01, 2012
As the pace of oil-and-gas production and recovery continue to grow in the U.S., the Griswold Pump Company's 811 Series ANSI centrifugal pumps are enabling oil-and-gas producers to maximize their production ability.
The 811 Series pumps can be a critical component in the saltwater handling and transfer applications in oil-and-gas recovery. Saltwater is a by-product of the production and needs to separate during the product recover process. The 811 Series pumps are ideal for transferred that water from the well bore and into storage tanks and trucks for disposal.
The 811 Series pumps have two times the wear area between the case and the impeller when compared to closed impeller designs, according to the Griswold Pump. This open-impeller design also minimizes wear by balancing the hydraulic axial thrust load and reducing the stuffing-box pressure. The result: Maximum pump performance, simplified maintenance, extended pump life, and reduced repair costs.
Pump buyers can choose from a wide range of casing materials including ductile iron, 316 stainless steel, CD4MCu and alloy 20. The pump construction included investment and no-bake casting processes, which yield smooth, precise finishes that guarantee consistent, reliable performance. Griswold also employs metallurgists to strictly supervise all heat-treating operations and ensure the maximum durability for all alloys.
Griswold 811 Series ANSI Centrifugal Pumps are available in a full range of sizes, as well as options and upgrades that can be tailored to meet virtually any liquid-handling flow rate, up to and including 4,000 gpm (908 m3/hr). There is a wide array of mechanical-seal options, all of which gives the pumps the ability to operate in temperatures as high as 500ºF (260ºC).
