Stainless Steel Marine Pump Housing Impeller CNC Precision Machining Service. High Efficiency: The CNC-machined impeller is precisely matched to the pump casing's flow path profile, resulting in hydraulic efficiency 8%-15% higher than that of cast pumps. Long Service Life: Precision fits minimise wear; the aluminium bronze impeller offers more than three times the cavitation resistance of standard stainless steel. Low Vibration and Low Noise: The impeller is dynamically balanced, and the pump housing and motor are precisely aligned, ensuring smooth operation. Easy Maintenance: Standardised interface design ensures high spare part interchangeability and facilitates disassembly, assembly, and maintenance. Suitable Media: Seawater, freshwater, bilge water, light oil, coolant, etc.
