Bronze Rotary Gear Pump - N1100

Exemplifies the excellence of positive displacement pumps, a category renowned for its precision and efficiency. This pump is a testament to robust design, integrating carbon-graphite bearings and a fluor elastomer lip seal, which are essential components for its high performance. The N1100 is a symbol of quality and resilience, crafted from premium bronze and featuring stainless steel 303 shafts. 

Solid Construction and High-Performance
The N1100's solid bronze construction ensures a long service life. Its mechanical seal outshines the variable back pressure challenges that often plague centrifugal pumps, types of pumps known for their sensitivity to such changes. Stainless steel shafts confer an additional layer of durability, making the N1100 a dependable workhorse. 


Efficient Bearings and Seals

At its core, the N1100 houses advanced carbon-graphite bearings renowned for their wear resistance and self-lubricating properties, enhancing the pump's longevity. These bearings ensure smooth operation with reduced maintenance intervals. Sealed with a fluoroelastomer lip seal, the N1100 offers exceptional chemical compatibility, vital for leak-free performance in chemical compatibility pumps. 


Easy Integration and Flexibility

Thanks to its motor adapter gear pump configuration, the N1100 can be easily assembled and connected to a variety of motors. This flexibility is ideal for those seeking a special motors gear pump setup or a standard one, enabling easy integration into diverse systems. 

Performance Across Conditions
A flexible coupling drive pump feature in the N1100 ensures efficient power transmission, making it adept at handling liquids with fine particulates—a notable characteristic of an abrasion-resistant pump. The close tolerance design of this gear pump is particularly effective for viscous fluids, maintaining performance even in less-than-ideal conditions.


Handling Extreme Temperatures
The N1100 is designed to operate efficiently across a vast range of temperatures, accommodating liquid temperatures from a frigid -40°F (-40°C) to a scorching 300°F (~149°C). This extreme temperature gear pump comes with freeze protection to prevent damage from the freezing of the pump's contents.


Powerful Suction and Self-Priming
With its rotary gear pump design, the N1100 delivers impressive suction lift, capable of elevating water up to 20 feet (~6.1 meters) on the suction side. This self-priming gear pump simplifies the startup process, particularly when the gears are pre-wetted, ensuring efficient operation from the start.


Oberdorfer Quality
As part of the reputable Oberdorfer pumps family, the N1100 benefits from a legacy of pump engineering excellence. It's an industrial gear pump that meets the demands of transferring various liquids, always performing reliably when coupled with bronze and fluoroelastomer seals. For those in need of enhanced chemical resistance, a nitrile lip seal variant is also available.


High Viscosity and Liquid Transfer
Excelling in the movement of viscous fluids, the N1100 serves as a high viscosity gear pump that maintains efficacy at lower flow rates, ideal for applications where precision liquid transfer is crucial.


Durable and Long-Lasting
The N1100's durable gear pump design and its construction from high-quality materials ensure a long-lasting solution for your fluid transfer needs, guaranteeing a greater return on investment over time.
