Griswold 811 Series Feature Enhanced Power Frames

The improved strength and rigidity of the 811 Series power frames are an estimated 33-percent stronger than competitive models, making them better equipped to withstand severe conditions found in many process and transfer applications.

In addition, the large sight glasses and magnetic drain plug are designed in features that provide longer bearing life for the 811 Series. Griswold® also utilizes a “Fusion Bonded Epoxy Coating” on the interior surface of the power frame to provide a superior barrier between the iron frame and oil, enhancing the long-term quality and cleanliness of the lubricating oil.

The 811 Series offers a full range of pump sizes, as well as options and upgrades that can be tailored to meet virtually any fluid-processing application with flow rates up to, and including, 908 m3/hr (4,000 gpm). Among the 811’s features are the availability of both 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 (500F). All 811 Series pumps undergo extensive hydro testing before being delivered to the customer.

Knowing that its customers deal in time-sensitive operations, Griswold has developed a manufacturing and inventory system that has been designed to handle a customer’s most critical needs. A ready-to-ship inventory coupled with a worldwide network of stocking distributors means that when a customer orders an 811 ANSI Series pump from Griswold, it is covered by a 36-hour emergency shipping commitment. Griswold also offers value-added services like inventory-optimization programs, technical support for equipment performance and engineering assistance in pump and component specification.
