FEATURES
Multi-stage Design: Provides steady, quiet, vibration free, operation.
Optional Stainless Steel Construction: Standard cast iron for general service or stainless for filtration applications.
O-Ring Casing Seal: Reliable high pressure sealing with easy disassembly for maintenance or repair.
Impellers and Diffusers: Glass filled engineered composite material with a fixed impeller design. High resistance to
corrosion and abrasion.
Bowls: 300 stainless steel rabbit lock for positive alignment with no gaskets required.
Variable Capacity: Centrifugal pump design permits selection of flow within a range for each size.
Mechanical Seal: A variety of face materials and elastomers to match application needs.
Motors: Close coupled NEMA 56J motors in open drip proof or totally enclosed design. Single phase and three
phase available. Ball bearings carry all radial and axial thrust loads. Designed for continuous operation.
5GB-25GB are tested to CSA-C22.2 No. 108-01.
®
5GBS-33GBS are CSA No. 32236914.

APPLICATIONS
• Residential, commercial or agricultural pressure wash
• Reverse osmosis
• Evaporative cooling systems/misters
• Booster service
• Spray systems
• Water circulation
• Filtration
• HVAC
• General purpose pumping
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 flow.
• If positive suction pressure is not available, be sure
pump and suction line (with foot valve) are primed
before starting pump.
