Bronze Rotary Gear Pump - N990

• Bronze Construction with Stainless Steel Shafts
  The N990 boasts a high-quality bronze body, making it a sturdy choice for any setting. The stainless steel shafts enhance this durability, providing a solid foundation for the pump's longevity. 

• Helical Gears For Quiet Operation
  Equipped with helical gears, the N990 operates with a whisper, setting the standard for quiet operation gear pumps. This feature is especially beneficial in environments where noise reduction is essential. 

• Easy Field Assembly to Motors
  The N990 is engineered to facilitate easy motor assembly, allowing for swift and hassle-free integration with a range of motor types. 

• Self-Lubricating Carbon Bearings
  Inside the pump, you'll find carbon-graphite bearings, which are self-lubricating, wear-resistant, and contribute to an extended service life, minimizing the need for ongoing maintenance. 

• O-Ring Seal For Max. Leak Protection
  An O-ring seal provides maximum leak protection, a testament to the N990's design, which prioritizes both efficiency and safety.

Drive
The N990, a close-coupled pump, directly mounts to electric motors via a suitable adapter bracket and employs a flexible coupling drive. This secure connection guarantees consistent and reliable power transfer from the motor to the pump. 

Liquids & Temperatures
Showowcasing remarkable pump liquid compatibility, the N990 can handle a variety of liquids, including water and oil, as well as mild chemicals. The pump is designed to perform within a temperature range of 32°F to 140°F (0°C to 60°C), accommodating various liquid properties and environmental conditions. 

Suction Lift & Pipe Size

• Pump Suction Lift: The N990's suction lift capability is impressive, enabling it to elevate liquids efficiently, a critical function for many applications. 

• Suction Pipe Size for Pumps: To achieve the best performance, especially when pumping viscous liquids, the suction pipe size should be appropriately matched to the pump's inlet port. 

Rotation and Relief Valve: 

• Gear Pump with Relief Valve: The N990 is outfitted with a relief valve to safeguard against excessive pressure buildup, an essential safety feature that ensures the pump operates within its designated parameters. 

• Clockwise Rotation Pump: This pump is set to operate with a clockwise rotation from the shaft end, but it can be reconfigured to accommodate different system requirements. 

For niche applications, the N990 series offers the clutch version gear pump N990-38 and the air motor driven gear pump N990S15H-T34, providing additional versatility.
