Bronze Pedestal Gear Pump - N9000

The Bronze Gear Pump - N9000 is a marvel of modern pump design, crafted to excel in a wide array of industrial applications. At the heart of its construction lies top-quality bronze for the pump housings and gears, ensuring the pump's resilience against corrosion. The use of 303 stainless steel shafts enhances the mechanical properties of the N9000, providing it with the strength and durability needed for industrial-grade work. 

Innovative Bearing Design
One of the N9000's standout features is its high-performance carbon-graphite bearings. These bearings are engineered for wear resistance and are expected to have a long service life, making them ideal for the rigorous demands of continuous pump work. The carbon-graphite material ensures that the bearings maintain their integrity and performance, even under the stress of heavy use. 


Positive Displacement Flow

As a positive displacement pump, the N9000 excels at liquid displacement, delivering a fixed volume of liquid with each rotation of the shaft. This precision is crucial for maintaining flow proportionality, especially in processes where consistent volume transfer is necessary. The pump's design ensures that flow is directly proportional to the shaft speed, providing a reliable and predictable output. 

Drive Configuration Flexibility
The N9000 can be configured with a direct drive and flexible coupling or a pulley drive. Avoid over-tightening the belt to ensure longevity. For higher pressures or larger pumps, external ball bearing support is recommended—consult the factory for details.


Compatible Liquids and Temperature Range
Designed for clean liquids with some lubricity, the N9000 avoids abrasives like sand or silt to prevent wear. It operates between -40°F to 400°F (-40°C to 204°C), with certain seals rated up to 212°F (100°C). Avoid extreme temperatures to maximize pump life.


Suction Lift and Self-Priming
The pump can lift water up to 20 feet (6.1 meters) on the suction side. Though self-priming, using a foot valve and pre-wetting gears improves startup performance.


Safety and Maintenance
The built-in by-pass valve acts as a pressure relief, factory-set at 50 PSI (3.4 bar), protecting against overheating. It’s not for flow control. Regular flushing and avoiding freezing liquids inside the pump are advised.


Industrial Use and Advantages
Ideal for precise flow control and pressure management, the N9000 is a reliable alternative to centrifugal pumps, especially with viscous fluids or variable pressures.


User-Friendly Operation
Flow is directly proportional to shaft speed, allowing easy adjustment to suit different tasks.


Maintenance for Longevity
Easy access to components facilitates routine cleaning and inspection, helping prevent wear from abrasives and seal degradation.
