Griswold’s E,F&G centrifugal pumps are designed for versatility! With capacities up to 3000 GPM, heads to 310 ft., a broad range of sizes and configuration options and extensive performance features, the E,F&G Series proves ideal for most water pumping applications.

E,F&Gs are equipped with your choice of either close-coupled NEMA electric motors or frame mounted with coupling to electric motors, engines, steam turbines or even belt-driven options. The E,F&G’s 360º mounting capabilities greatly extend installation options. Close-coupled configurations can be mounted vertically when space is at a premium. The E,F&G’s back pull-out design permits removal of the pump assembly for easy maintenance without disturbing pipe connections. All E,F&G models are flanged in accordance with ANSI B 16.1 for 125 PSI applications.

In addition to the wide variety of options and upgrades available to configure the Series for your specific application, all E,F&G pumps are engineered for performance, long life and easy maintenance with standard features such as:

Cast Iron Casing:
Our class 30 grade iron casing is tapped for a drain, vent and pressure gauge, includes a suction wear ring and can be rotated to various discharge positions. Standard ANSI flange-type suction and discharge nozzles facilitate installation and maintenance.
 
Shaft Sleeve:
The renewable bronze shaft sleeve insulates the shaft from abrasion and contact with pumped liquids.
 
Impeller:
Made of cast bronze and keyed to the shaft, our single-piece enclosed impeller is precision balanced with the diameter cut for the specific condition point. On high-head units, the impeller back is drilled for hydraulic balance, limiting thrust load and reducing pressure in the sealing area.
 
Wearing Rings:
Precision-made bronze wear rings are pressed into the casing and/or adapter as required and are renewable as well as easily replaced in the field.
 
Mechanical Shaft Seals:
Our mechanical seals feature Carbon/Ceramic/Buna and stainless steel components, eliminating maintenance and adjustment problems. A bypass line on some models helps purge abrasives from the seal chamber.
