Rotary Gear Pumps GA Series Cast Iron, Double Helical
The Flowserve GA cast iron series, double helical, herringbone type gear pumps are designed to handle viscous fluids at low to medium flows and pressures. These rugged pumps provide highly efficient, pulse-free pumping even under the most challenging conditions.
Applications:
OEM, Process, Petrochemical Processing, Marine, Food Processing, Greases and Fats, High Viscosity Polymers, Syrups
Industries:
Food Processing, Miscellaneous Services, Auxiliary, Pharmaceuticals, OEM
Double Helical Herringbone Gears provide quiet, pulse-free flow with better load carrying ability, greater strength and minimum hydraulic shock.
High-Speed Pump Capability eliminates the need for expensive speed reduction accessories and allows the use of off-the-shelf motors.
Between Bearings Design virtually eliminates shaft deflection, even while accommodating heavy, highly viscous loads.
Standard Babbitted Carbon Sleeve Bearings are self-lubricated for handling low viscosity fluids. Bronze bearings are available for dirty fluid applications.
Inherently Hydraulically Balanced Design eliminates end thrust and the need for thrust bearings.
Convertible Stuffing Box allows for ample packing or mechanical seals to be used for greater flexibility.
