ZW Self-Priming Sewage Pump Performance Examples – Model ZW25, ZW50, ZW100 & ZW150

The ZW self-priming sewage pump series includes multiple models to meet different flow and head requirements. Below are representative performance examples:

The ZW25-8-15 model has a rated flow of 8 m³/h, rated head of 15 meters, motor power of 1.5 kW, speed of 2900 r/min, efficiency of 45-55%, and self-priming height of 5.5 meters. This compact model is ideal for small-scale applications.

The ZW50-15-30 model delivers 15 m³/h flow at 30 meters head with 3 kW motor power at 2900 r/min. The ZW100-80-45 model provides 80 m³/h flow at 45 meters head with 30 kW motor power. The ZW150-180-14 model achieves 180 m³/h flow at 14 meters head with 15 kW motor power at 1450 r/min.
These examples demonstrate the wide range of performance available in the ZW series, from small portable units to large industrial pumps.
