ANSI Standard Dimensions ~ American Made Extra Heavy Castings ~ Fully Interchangeable
Outstanding Performance & Design Features
ANSI standard dimensions allow easy installation of replacement pumps.
Wide range of seal design options permit the use of the right seal for the job.
Interchangeable components enable quick, on- site exchange of replacement assemblies.
Three sizes offer a wide range of pumping capacity.
E, F & G SERIES END-SUCTION CLOSE COUPLED OR FRAME MOUNTED CENTRIFUGAL PUMPS
Designed for capacities up to 3000 GPM and heads to 330 feet, GRISWOLD E, F & G Series centrifugal pumps can be close coupled, flexible-coupled to electric motors, engines or steam turbines. They can also be belt driven.
E, F & G Series pumps are ideal for a wide variety of liquid pump applications, including crop and turf irrigation, water parks, swimming pools, fountains, air conditioning, water supply systems, and many other general industrial applications.
They are available in a wide range of sizes and performance characteristics. All models are flanged in accordance with ANSI B16.1-1975 for 125 PSI applications.
Standard design features:
Frame - The heavy duty cast iron support head is precision bored for rigid alignment of shaft and bearings. The coupling bearing is locked while the stuffing bearing floats, thus reducing end play to a minimum. Bearing covers include shaft seals to eliminate dirt, water or moisture damage. The precision ball bearings are grease lubricated.
Close Coupled Motors - Standard drip-proof NEMA JM and JP. These close coupled motor designs provide a short shaft overhang and reduce the effects of axial strain on motor bearings. Motor bearings are factory lubricated and sealed for long life. Totally enclosed and explosion proof motors are also available.
Casing - Cast of heavy-duty cast iron, the casing is tapped for drain, vent and pressure gauge. Suction and discharge nozzles are standard ASA flanged type for easy installation. The casing can be rotated for various discharge positions. A suction wear ring is included.
Shaft Sleeve - The renewable bronze shaft sleeve is keyed to the shaft and protects the shaft from abrasion and any contact with the liquid.
Impeller - Single piece enclosed design. Close grain cast bronze, fully balanced with the diameter cut for the specific condition points. High head units have back of impeller vented to suction to achieve hydraulic balance, limit thrust load, and reduce pressure in the sealing area.
Mechanical Shaft Seals - Leakless mechanical shaft seals with steel components eliminate maintenance and adjustment problems. A bypass line on some models helps prevent dead-ending of abrasives in the seal chamber.
Wearing Rings - The renewable precision bronze wearing rings are pressed into the casing and/or adapter as required. Easily replaced in the field.

GRISWOLD 811 ANSI Centrifugal Pumps
GRISWOLD’s Model 811 meets or exceeds all ANSI standards for the chemical processing industry. The fully open impeller, centerline discharge, and other unique design features allow the 811 to continue operating long after other ANSI pumps wear out or break down. For example:
A choice of extra-heavy-duty, stocked, Ductile Iron, Stainless Steel, Alloy 20 and CD4M pump materials coupled with multiple seal design options allows you to tailor the 811 to virtually any process flow application.
The fully-open impeller design features large wear areas and back pump-out vanes, making the 811 far superior in handling corrosive and erosive fluids. Open impellers balance hydraulic axial thrust loads, lengthen bearing life, and reduce stuffing box pressure too.
The self-tightening impeller with O-ring seal eliminates part corrosion, gasket leakage, and all chance of loosening in high temperature environments.
Replaceable shaft sleeve and adapters allow easy replacement of sealing surface without shaft and bearing disassembly, without bearing contamination.
Any external clearance adjustments due to wear can easily be made on-site with an ordinary open-end wrench. No shimming is required.
Parts Interchangeable with Goulds 3196 and Peerless 8196 with savings of up to 50%. Same day service on parts with no premium on price. Griswold’s high-quality ANSI parts are performance-tested to meet performance curves, yet their standard prices are the lowest of any pump manufacturer
And best of all, the Model 811 is available in a wide range of sizes and capacities to fit virtually any process fluid application. The Griswold 811 ANSI pump can make your life simpler by replacing a warehouse full of pumps, including:
Allis Chalmers CSO, 731+
Dean
Duriron Mark II and III
Gould 3196
Ingersoll Rand HOC
LaBour
Peerless 8196
Worthington D1000
And all with no piping changes, no baseplate changes and no coupling changes required!

Self-Priming Centrifugal Pumps
Engineered for industry . . . with a choice of electric or flexible coupled design.
GRISWOLD self-priming centrifugal pumps are designed for a variety of applications. For example, they can be used for draining barges and tank cars . . . dewatering mines or underground storage facilities. Homeowners use them for sprinkler systems and swimming pools. When it comes to moving water from one place to another, there’s not end to the jobs that a GRISWOLD Self-Priming Pump can handle!
Take a Look at These Features:
Fast, Positive Priming: Pressures in the case and in the volute are balanced during pumping, preventing any loss of capacity from recirculation. In operation, you get maximum pumping capacity at lowest cost.
Semi-Open Type Impeller: High efficiency, semi-open type impeller with clearance easily adjustable to compensate for wear after extended service, even with abrasive liquids.
Mechanical Shaft Seal: The open type mechanical seal is the finest available. All metal parts are chrome nickel stainless steel. The stationary seal face is made of optimum grade ceramic, resiliently mounted. The self-lubricating carbon rotating seal face assures longer, more reliable operation with a minimum of wear.
Heavy Duty Case: Highest quality, close grain cast iron case construction features thick wall sections for more rugged operation under adverse pumping conditions . . . yet the entire pump is amazingly lightweight.
Perfect Alignment: A heavy-duty rigid bracket maintains perfect alignment between the centrifugal pump and the motor.
