Description

The 790149 HUB - 1 7/8 Blackmer pump hub is manufactured by Blackmer and distributed by KI Pumps of Waukesha, WI. It is designed specifically for use with positive displacement pumps, including rotary and reciprocating types, ensuring precise fitment and reliable operation. This pump hub is constructed from durable materials, facilitating long-term performance and resistance to corrosion under typical operating conditions.

Dimensional specifications include an outer diameter of 1 7/8 inches, with a bore diameter compatible with shaft sizes designed for this hub model. The hub features a robust design capable of handling high torque loads without deformation, making it suitable for demanding pump applications. It weighs approximately 0.45 kg, which aids in maintaining the balance and stability of the pump assembly during operation.

Key features of the 790149 HUB include:

  • Manufactured from high-strength alloy steel for durability and wear resistance
  • Precisely machined for a slip fit with Blackmer pumps and compatible shafts
  • Designed to accommodate specific coupling configurations for reliable drive transmission
  • Corrosion-resistant finish suitable for industrial environments
  • Standard dimensions ensure compatibility with 1 7/8 inch drive shafts

This 790149 HUB is ideal for maintenance and replacement in industrial settings, such as chemical processing, water treatment, and oil and gas applications. It is suitable for use in new pump assembly setups or as a replacement part for worn or damaged hubs, supporting continuous, high-performance pump operation. It is especially beneficial for facilities prioritizing durability and precise fitment for high-torque positive displacement pumps.

Each 790149 HUB ships in a secure packaging box, including the hub itself and installation hardware. Not included are the coupling components or shaft modifications required for installation. Proper installation should be performed according to Blackmer specifications.
