Rotor 2L8
Description
Rotor 2L8 – Cobra 2
Heavy-Duty Rotor for the 2L8 Screw Pump
Made in Germany
The 2L8 Rotor is the matching replacement rotor for the 2L8 screw pump, also known as Cobra 2. The 2L8 is a high-output progressive cavity pump designed for demanding applications involving concrete, mortar, screed, and other pumpable construction materials.
Manufactured in Germany from high-alloy tool steel, the 2L8 rotor is available with either a square or hexagonal rotor head, depending on the required machine configuration.
The rotor is designed for use with the matching 2L8 Stator. For a complete pump replacement, we recommend the 2L8 Rotor Stator Set.
