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.

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 no 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 the 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.
