A Guide to Griswold's 811 ANSI Series: Features, Benefits, and Applications
In the world of industrial fluid handling, reliability, efficiency, and ease of maintenance are non-negotiable. When choosing a centrifugal pump, especially one designed to meet ANSI B73.1 standards, operators need a solution that can perform under pressure, simplify system design, and minimize long-term costs. That’s where the Griswold 811 ANSI Series shines.
Engineered for tough operating environments and known for its broad range of sizes and materials, the Griswold 811 is a direct competitor to legacy pumps like the Goulds 3196—but with unique advantages in performance, lead time, and serviceability. Whether you’re upgrading your facility, replacing a legacy pump, or building a new system from scratch, the Griswold 811 offers a flexible and economical solution.
In this post, we’ll take a detailed look at the 811 ANSI Series—what sets it apart, how it performs, and why Process & Power, with offices in Memphis and Jackson, Tennessee; Springdale and Little Rock, Arkansas; and Tupelo, Mississippi, recommends it to industrial clients across the Southeast.

What Is the Griswold 811 ANSI Series?
The Griswold 811 ANSI Series is a line of horizontal, single-stage, end-suction centrifugal pumps designed to meet ANSI B73.1 dimensional standards. This means they are fully compatible with other ANSI-standard pumps, making them ideal for retrofits and replacements.
The 811 Series is designed to deliver reliable, efficient performance in applications that involve:
Chemical processing
Pulp and paper manufacturing
Wastewater treatment
Food and beverage production
Oil and gas transfer
Water purification and boiler feed systems
Each model is engineered for back pull-out service, which allows maintenance teams to service internal components without disturbing piping—a key time-saver for high-usage facilities.
Key Features of the Griswold 811 ANSI Series
The 811 Series is built with durability, flexibility, and total cost of ownership in mind. Here’s what makes it stand out:
28 casing sizes for high-performance hydraulic coverage
Flow rates up to 7,000 GPM
Heads to 730 feet
Wide range of material options: ductile iron, 316 stainless, Alloy 20, CD4MCu
Open or enclosed impellers based on application
Back pull-out design for easy maintenance
Interchangeable with other ANSI-compliant pump lines
Multiple seal chamber configurations including standard, enlarged, and ISO
Its ability to meet a broad spectrum of flow and pressure requirements makes it a true workhorse in industrial pumping systems.
Advantages Over Competing Pumps
When compared to other ANSI-standard pumps such as the Goulds 3196, the Griswold 811 offers several performance and value-driven benefits.
Simplified hydraulic coverage: Griswold’s 28-size system provides the same flexibility with fewer models to stock

Maintenance Benefits
The Griswold 811 is designed to make maintenance as efficient and straightforward as possible. That includes:
Back pull-out design allows removal of the rotating assembly without disturbing the suction and discharge piping
Interchangeable components simplify inventory and reduce training needs
ANSI dimensions mean easier swap-outs and compatibility with competitor mounting systems
Wear rings and seal options allow for extended service life
Enhanced bearing frames for higher load capacity and longer life expectancy
With minimal special tools required and easily accessible internals, facilities can cut down on both downtime and labor costs.
Real-World Example: Industrial Plant Retrofit in Little Rock
A regional manufacturing plant in Little Rock, Arkansas, needed to replace five legacy centrifugal pumps used in a process water system. The old units required frequent service, parts were no longer stocked, and downtime was affecting throughput.
Process & Power proposed the Griswold 811 ANSI Series with ductile iron casings and 316SS impellers to handle light abrasives and temperature fluctuations. The results:
Full installation completed with zero piping modifications
Efficiency improved by 11% across the system
Maintenance frequency dropped by 40%
All five pumps now share the same spare parts inventory
