Description
Flowserve GR Series Double Helical Between Bearings Gear Pump
Previously known as Worthington GR Series, the Flowserve between bearing gear pump is capable of flow rate as high as 275m3 per hour (1200gpm). This series of positive displacement pump are designed to handle viscous fluids across different various applications under the most challenging conditions. With it's between bearing design, it minimizes shaft deflection and reduces bearing loads, improving high-pressure and high-speed capabilities while increasing efficiency and lowering costs.
Applications:
Marine, High Viscosity Polymers, Greases and Fats, Food Processing, Syrups, OEM, Petrochemical Processing, Process, Power Generation, Pulp and Paper, Utility
Industries:
OEM, Pharmaceuticals, Auxiliary, Food Processing, Miscellaneous Services
Benefits of Flowserve GR Series Gear Pump
- Double Helical Herringbone Gears provide quiet, pulsation-free flow with better load carrying ability, greater strength and minimum hydraulic shock.
- High Speed Pump Capability eliminates need for expensive speed reduction accessories and allows the use of off-the-shelf motors.
- Between Bearing Design virtually eliminates shaft deflection, even while accommodating heavy, highly viscous loads.
- 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.
