Introducing the 261831 Rotor and Shaft by Blackmer, a replacement component designed for precise operation in positive displacement and sliding vane pumps.

The 261831 Rotor and Shaft consists of a durable assembly constructed from high-quality materials including hardened steel and precision-machined components. Its construction is engineered to withstand continuous operation, resisting wear and corrosion to ensure longevity and consistent performance over time.

Specifications include a length of approximately 10 inches (254 mm) and a diameter of around 2 inches (50 mm), with the rotor and shaft assembled to fit models that utilize this specific part number. It is compatible with Blackmer's lines of positive displacement pumps, particularly those employing sliding vane mechanisms.

  • Material composition: hardened steel and precision-machined components for durability
  • Dimensions: approximately 10 inches (254 mm) in length, 2 inches (50 mm) in diameter 
  • Application: suitable for use in positive displacement and sliding vane pumps
  • Design features: accurately balanced rotor with a precision shaft for smooth rotation and minimal vibration
  • Operational benefits: ensures efficient power transfer, reduces downtime, and extends pump service life

This 261831 Rotor and Shaft is ideal for maintenance, repair, and replacement to sustain the reliable operation of your pump system. It is especially suitable for industrial facilities, water treatment plants, and processing industries where positive displacement pump performance is critical.

Included in the package is the assembled rotor and shaft unit; additional mounting hardware or seals are not included and should be purchased separately based on specific pump model requirements. The component requires no special tools for installation.

To maintain optimal performance, the rotor and shaft should be inspected periodically for signs of wear or corrosion. Regular lubrication of the shaft is recommended, and a professional service is advised for replacement or repairs.
