Performance Characteristics
- Wide Range of Flow and Pressure: The flow rate generally ranges from 5 to 45 L/S, and the pressure ranges from 0.18 to 2.61 Mpa. The number of pump stages can be increased or decreased as required, and the outer diameter of the impeller can be trimmed to meet different flow and pressure demands.
- High Efficiency: It adopts an energy-saving design. For instance, some horizontal multi-stage fire pumps use a high-speed structure. Compared with medium-speed fire pump units, they have fewer stages, reduced unit length and weight, and thus improved efficiency.
- Stable Operation: Low-noise sealed bearings are used. The components have high concentricity, and the impeller features good dynamic balance, ensuring vibration-free operation with low noise. Additionally, the seal is reliable without leakage.
