ZW Self-Priming Sewage Pump Technical Parameters – Flow, Head, Power & Dimensions

The ZW self-priming sewage pump covers a wide range of technical parameters to suit various applications. The flow rate ranges from 5 to 800 m³/h, and the head ranges from 12 to 60 meters. Motor power varies from 1.5 to 55 kW, with rotational speeds of 1450 to 2900 r/min.

The pump inlet and outlet diameters range from 25 mm to 300 mm. Self-priming height reaches 4.5 to 6.0 meters, and the maximum suction pipe length is 10 meters. The pump can handle media temperatures up to 80°C under normal conditions, with special versions reaching 100°C or higher.

For solid handling, the pump passes particles up to 60% of the pump diameter and fibers up to 5 times the pump diameter. Media specific gravity should not exceed 1240 kg/m³. Efficiency ranges from 45% to 68%, and NPSHr ranges from 2.0 to 6.0 meters. Pump weight varies from 100 to 1400 kg depending on model and material.
