GFHF SERIES
CENTRIFUGAL ELECTRIC PUMPS
MOTOR-PUMP COUPLING
Three different types of motor/pump coupling are
available:
• GFHE: close-coupled by means of an adaptor bracket
with an impeller keyed directly to the motor shaft
extension.
• GFHS: with a bracket, adaptor and rigid coupling
keyed to the standard motor shaft extension.
• GFHF: with bracket, support, flexible coupling and
aligning and anchoring base.
• Bare shaft pump and version with spacer coupling
are also available upon request.
