Oberdorfer N11HDM-06 Bronze Gear Pump End €“ 1-1/4" NPT
The Oberdorfer N11HDM-06 is a heavy-duty bronze pedestal gear pump designed for reliable, continuous fluid transfer across industrial, commercial, and utility applications. Built with precision-machined bronze gears and a stainless steel shaft, this pump delivers consistent flow performance while maintaining excellent corrosion resistance in demanding environments. As a pump end (less clutch), it is ideal for integration into custom drive systems requiring flexibility and durability.
Engineered as a positive displacement pump, the N11HDM-06 provides steady, predictable flow directly proportional to shaft speed, making it highly efficient for controlled fluid movement. Its self-priming capability and high suction lift (up to approximately 20 feet) allow dependable operation even in challenging setups. The Buna mechanical seal ensures long service life when handling compatible fluids such as water, oils, diesel, and mild chemicals.
Designed for longevity and low maintenance, this pump features carbon-graphite bearings and tight internal tolerances that maximize efficiency while minimizing wear. The Oberdorfer N11HDM-06 is a proven solution for professionals who demand consistent performance in fluid handling systems where reliability is critical.

FAQ
What does €œpump end less clutch€? mean for the N11HDM-06?
It means the unit includes only the pump assembly without a clutch or motor, allowing custom integration into existing drive systems.
Can the N11HDM-06 handle viscous fluids?
Yes, it can handle high-viscosity fluids up to approximately 50,000 SSU, though lower speeds are recommended for thicker liquids.
Is the Oberdorfer N11HDM-06 suitable for abrasive fluids?
No, gear pumps like the N11HDM-06 require clean, non-abrasive fluids to prevent premature wear.
What makes this pump self-priming?
Its gear design creates suction that allows it to draw fluid without pre-filling the system.
Can this pump be used outside marine environments?
Yes, it is widely used in industrial, agricultural, HVAC, and municipal applications€”not just marine systems.
