Casting steel Low Speed Impellers
Low-speed impellers used in construction machinery typically refer to impellers with lower specific speeds. Their core characteristics are high head and low flow rates, making them commonly used in applications requiring high pressure or high head. These impellers feature a narrow, long flow path design and a reduced blade outlet width, resulting in improved cavitation resistance.
Specific Characteristics
Low-speed impellers operate at lower speeds under similar operating conditions, generating higher head at a relatively low flow rate. For example, impellers used in high-pressure or high-head centrifugal pumps in construction machinery typically feature long, narrow flow paths to achieve higher head performance.
Applications
This type of impeller is commonly found in:
Mine dewatering equipment
High-pressure cleaning equipment
Industrial cleaning systems
Special fluid transport applications (such as fluids containing large particles)
