Bronze Pedestal Gear Pump - N13500

The Bronze Gear Pump N13500, a pinnacle of engineering in the positive displacement gear pump category, designed to handle a myriad of industrial applications with unmatched efficiency. This high-quality bronze gear pump is built with resilience in mind, featuring bronze corrosion-resistant castings and sturdy 303 stainless steel shafts, making it an ideal stainless steel shaft gear pump for any challenging environment. 

  • Bronze Corrosion Resistant Castings:
    The N13500's housing and gears, crafted from superior bronze, offer exceptional resistance to corrosion, embodying the pump's durability. 
  • Stainless Steel Shafts & Fasteners:
    This pump is equipped with stainless steel shafts and fasteners, reinforcing its overall robustness and ensuring a long service life. 
  • Self-Lubricating Carbon Bearings:
    High-performance carbon-graphite bearings, known for their wear resistance, are self-lubricating, which contributes to the pump's low maintenance and consistent operation. 

  • Packing (Braided Acrylic yarn with special lubricant and Graphite):
    The acrylic graphite packing pump system provides reliable sealing and is compatible with a range of liquids. 

  • Optional Fluoroelastomer Lip Seal:
    For applications requiring enhanced sealing capabilities, an optional fluoroelastomer lip seal gear pump is available, complete with PTFE backup and a stainless case for added chemical resistance. 

For those requiring a mechanical seal gear pump, the N13500 can be outfitted with various seal options to meet specific operational needs.

Drive

The N13500 offers flexibility with its drive options, accommodating both direct drive gear pump setups with flexible coupling and pulley drive gear pump configurations. When using a pulley system, a pillow block bearing gear pump design is recommended to manage belt tension effectively and maintain proper gear pump alignment. 

Liquids & Temperatures

The longevity of the N13500 is significantly enhanced when pumping clean liquids with lubricity. Its design allows for a wide temperature range gear pump operation, withstanding conditions from -40°F to 400°F. The acrylic graphite packing is rated to 500°F, and the fluoroelastomer lip seal to 300°F. To maximize gear pump service life, it is advisable to avoid temperature extremes and ensure the pumped liquid remains clean, free from fine abrasives that could compromise the pump's close tolerances. 

Suction Lift: 

High Suction Lift Gear Pump:
As a rotary gear pump, the N13500 is capable of impressive suction lift, reaching heights of up to 20 feet. While inherently a self-priming gear pump, the addition of a gear pump foot valve is recommended to enhance this feature and ensure peak performance. 


For those seeking a gear pump for viscous liquids, the N13500 is well-suited for applications involving molasses, oils, or other heavy liquids, although it may require operation at a lower pumping speed. Large suction lines are essential for preventing cavitation, which can lead to pump destruction. If you're handling liquids with specific gravities greater than water, such as dry cleaning fluids, an increase in motor horsepower proportional to the specific gravity is necessary. 

The Bronze Gear Pump - N13500 is a versatile, durable, and efficient solution for those in need of a reliable industrial gear pump. Whether you're looking to buy gear pumps online, request a gear pump quote, or require gear pump maintenance, our team is here to support your needs. With the N13500, you'll benefit from a pump that offers chemical compatibility, abrasion resistance, and the ability to handle a wide range of temperatures and liquid properties.
