APPLICATIONS
• Residential, commercial or agricultural pressure wash
• Reverse osmosis
• Evaporative cooling systems/misters
• Booster service
• Spray systems
• Water circulation
• Filtration
• HVAC
• General purpose pumping
SPECIFICATIONS
Pump
• Maximum suction (inlet) pressure: 75 PSI.
• Maximum Liquid Temperature: 160º F (71º C).
• Rotation: Clockwise when viewed from motor end.
• Maximum lift with foot valve: 10 ft., check NPSH curve.
Motor:
• NEMA standard 56J frame.
• Open drip proof or totally enclosed fan cooled enclo-
sures available as standard. Consult factory for other
options.
• 60 Hz, 3500 RPM. Single phase (115/230 V), three
phase 208-230 (3 HP, 230 V) or three phase (208-
230/460 V).
• Single phase motors have built-in capacitor and over-
load with automatic reset.
Note: For three phase motors, Class 20 overload protec-
tion must be provided in starter unit. Starter with over-
loads must be ordered separately.
MATERIALS OF CONSTRUCTION
WARNINGS
• Pumps used on open spray applications must be
plugged into electrical service which is protected by a
Ground Fault Service Interruptor. Failure to do so may
result in serious personal injury or death and property
damage.
• Do not run pump dry.
• Do not run pump below minimum ow.
• If positive suction pressure is not available, be sure
pump and suction line (with foot valve) are primed
before starting pump.

GB NUMBERING SYSTEM
The various versions of the Series GB are identied by a product code number on the pump label. This number is also
the catalog number for the pump. The meaning of each digit in the product code number is shown below. The follow-
ing are the standard 60 Hz product numbers and are built with Single Phase ODP motors and standard staging. The cast
iron version uses Seal Code 0 and the stainless version uses Seal Code 4.
