Features:

  • All Bronze Castings and Stainless Steel Shafts:
    The N13HD is constructed with top-quality bronze and 303 stainless steel shafts, making it a highly durable gear pump that resists corrosion and wear.
  • Self-Lubricating Carbon Bearings:
    Equipped with carbon-graphite bearings, this pump boasts self-lubricating properties, reducing the need for frequent maintenance and enhancing operational longevity.
  • Electric Clutch Options:
    For applications requiring precise control, the N13HD offers optional gear pump electric clutch configurations, providing versatility and ease of use.

Performance:

Drive & Alignment:
The N13HD functions optimally as a direct drive gear pump, though it can also be configured for belt drive systems. Proper gear pump alignment is vital for achieving satisfactory pump life and should be checked after installation.

Noise:
Recognizing the importance of a low-noise gear pump, the N13HD has been designed to minimize operational sound, making it suitable for installation in quieter workspaces.

Suction Lift:

High Suction Lift Gear Pump:
This pump is capable of impressive suction lift, reaching up to 20 feet (6 m), categorizing it as a high suction lift gear pump that can handle challenging fluid transfer tasks with ease.

Self-Priming Gear Pump:
The N13HD is also self-priming, adding to its reliability and ease of operation, although the use of a gear pump foot valve is recommended to ensure peak performance.

For those who require a pump that can handle high-temperature liquids, the N13HD is an excellent choice. Its construction allows it to function effectively as a gear pump for high-temperature liquids, while also being abrasion resistant and suitable for clean liquid applications.

 

Seal Conversion Kits

Seal conversion kits illustrated (on back) are designed for quick removal and replacement. In each case, seal housings are fastened to pump bodies by means of 2 bolts, item 13. IMPORTANT - before attempting to remove a seal housing containing seal components by sliding them off the pump shaft, be sure to unlock the 2 set screws locking the ball bearing inner race to the pump shaft. The ball bearing is identified as item 20. Also, before attempting to slide the seal housing from the pump shaft, remove all burrs, scale, and projections that could be formed by fretting corrosion. 

Service Wear Factors

  • Speed:
    As a low-speed gear pump, the N13HD is designed to operate at lower speeds to reduce wear and extend its service life. Pump speeds above 900 RPM. not recommended except for intermittent duty and pressures below 100 psi (6,9 bar)

  • Pressure:
    This high-pressure gear pump is capable of handling demanding conditions, but maintaining the lowest pressure necessary for your application will help to preserve the pump's integrity. 

  • Liquid Lubricity:
    The pump's service life can be significantly enhanced by using liquids with lubricating properties or adding lubricant additives when possible.
