Suitable for offshore, water and wastewater technology, power plants, desalination, trunk mains, pipelines, and pumping stations.

Key Features:

Triple shaft bearings and single flange mounting.
Adjustable bearings up to DN600 for pressures ≥ 16 bar.
Temperature range: -40°C to +200°C, depending on pressure, medium, and material.
Operating pressure: max. 25 bar; Differential pressure: max. ∆p 25 bar.
Vacuum capability up to 1 mbar absolute.

Performance Parameters:

Kv-values indicate the flow of water at temperatures between 5°C to 30°C at a ∆p of 1 bar.
Maximum permissible flow velocity: 4.5 m/s for liquids and 70 m/s for gases.
Throttle function is linear between 30° to 70° angles.
Avoid cavitation for optimal performance.

Torque and Material Specifications:

Initial breakaway torques are provided for liquids and lubricant media, with adjustments for powdery and dry gases/high viscous media.
Material specifications include nodular cast iron, stainless steel, and various rubber compounds for different components.
