Heavy Duty End Suction Centrifugal Pumps Ideal for Irrigation Applications

Backed by Griswold’s 70 years of experience and commitment to manufacturing quality centrifugal pumps, E,F&G Series pumps have been specifically designed with versatility in mind. With capacities up to 682 m3/h (3,000 gpm), heads to 95 meters (310 feet), a broad range of sizes and configuration options, and extensive performance features, the E,F&G Series pumps are ideal for a wide variety of water pumping applications. These pumps are equipped with a choice of either a close-coupled NEMA electric motor or frame mounted with couplings to electric motors, engines steam turbines or belt-driven motors. The EF&G Series pump’s 360-degree mounting capabilities extend installation options, while its close-coupled configurations can also be mounted vertically when space is at a minimum. The back pull-out design permits removal of the entire pump assembly for easy maintenance without having to disturb the piping connections. All E,F&G Series models are flanged in accordance with ANSI B 16.1 for 125-psi applications.

Other key components of E,F&G Series pumps include:

• Shaft Sleeve– The renewable bronze shaft sleeve insulates the shaft from abrasion and contact with pumped liquids
• Mechanical Shaft Seals - The carbon, ceramic, Buna and stainless steel components drastically reduce maintenance and adjustment issues
• Single-Piece Enclosed Impeller – Made of cast bronze and keyed to the shaft, the enclosed impeller is precision balanced with the diameter cut for the specific condition point
• Wear Rings – Renewable, the precision-made bronze wearing rings are pressed into the casing and/or adaptors as required and are easily replaced in the field
