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:
Griswold's 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:
Griswold's 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.
