Griswold ANSI Pumps Meet Needs For Saltwater Transfer in Oil & Gas Applications


Griswold Pump Company is pleased to announce that, as the pace of oil-and-gas production and recovery continues to grow in the United States—especially in the fertile shale-oil plays—its 811 Series ANSI Centrifugal Pumps possess a “speed to market” rate that enables oil-and-gas producers to maximize the production ability of their operations.

Griswold 811 Series pumps can be critical components for use in saltwater handling and transfer applications in oil-and-gas recovery. Saltwater is by-product of oil-and-gas production and, as such, needs to be separated during the product-recovery process. The 811 Series pumps are ideal for transferring the collected saltwater out of the well bore and into storage tanks or trucks so that it can be disposed.

The 811 Series pumps meet the needs of this oil-and-gas application because they have two times the wear area between the case and impeller when compared to closed impeller designs. The open-impeller design also minimizes concentrated wear by balancing the hydraulic axial thrust load and reducing the stuffing-box pressure. This not only maximizes the pump’s performance, but also simplifies maintenance, extends pump life and reduces repair costs.

These pumps also have casings that can be constructed of a wide choice of materials, including ductile iron, 316 stainless steel, CD4MCu and alloy 20. They are constructed through investment and no-bake casting processes to ensure smooth, precise, superior finishes that guarantee consistent, reliable performance. Griswold also employs metallurgists to strictly supervise all heat-treating operations so that maximum durability for all alloys is ensured. Other features of the 811 ANSI Series are self-tightening impellers that reduce leaks and failures; the ability to externally adjust the clearance so that peak efficiency is ensured even after wear-area loss; and optional enhanced power frames that make them an estimated 33% stronger than competitive models.

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).
