What are CNC-Machined Slurry Pump Impellers?
CNC-machined slurry pump impellers are rotating parts that form part of a greater machine. They change mechanical energy to kinetic energy using centrifugal force. These impellers can have dimensional tolerances of ±0.1 mm, but the exact dimensions depend on the specific applications. The machining process gets rid of casting defects and porosity issues, as these can really lower part lifespan in abrasive environments.
Key Design Features
- Closed impeller, semi-open, and open impeller configurations
- Vane quantities from 2 to 6 depending on application requirements
- Diameter range from 25 mm to 560 mm (1″ to 22″)
- Maximum particle handling up to 130 mm diameter
- Slurry concentration capacity up to 70% by weight
Performance Advantages
CNC manufacturing creates smooth surface finishes of Ra 1.6 μm that reduce turbulence and improve flow characteristics. Modern centrifugal slurry pumps keep high efficiency ratings up through precision blade geometry. The controlled manufacturing process ensures consistent hydraulic profiles that maintain performance throughout extended service life in mining industry applications.
