Key Features & Advantages
- Stainless Steel Shaft: The pump shaft is constructed from corrosion-resistant stainless steel, enhancing durability and reliability, especially when handling mildly corrosive liquids or in humid environments.
- Y2 National Standard Motor: Powered by high-efficiency, reliable Y2 series three-phase motors that comply with national standards, ensuring stable performance and energy savings.
- High-Temperature Resistant Bearings: Equipped with bearings specifically rated for high-temperature operation. This design allows the pump to handle hot liquids (up to specified limits) and withstand the thermal stresses of continuous duty, extending component life.
- High-Temperature Mechanical Seals: Incorporates mechanical seals designed with high-temperature-resistant materials. This is critical for maintaining a reliable seal when pumping hot water or other heated fluids, preventing leakage and premature seal failure.
Model Number Instruction
Understanding the model code provides key specifications:
- BZ: Self-Priming Centrifugal Pump
- First two digits (e.g., 40, 50, 65): Inlet/Outlet Nominal Diameter (mm)
- First Number after “BZ” (e.g., 10, 15, 20): Rated Flow (m³/h)
- Second Number after “BZ” (e.g., 20, 25, 15): Rated Head (m)
- The final number in some model codes indicates power (kW), but in the BZ series table, power is listed as a separate column.
Example: 40BZ10-20= Self-priming centrifugal pump with 40mm ports, 10 m³/h flow, 20m head.
