Understanding ZW Self-Priming Sewage Pump Model Numbers – Complete Guide

The ZW self-priming sewage pump model number provides important information about the pump’s specifications. A typical model is expressed as “50ZW15-30PB”. Breaking down this model number:
•
“50” represents the pump inlet diameter in millimeters (mm)
•
“ZW” stands for self-priming non-clog sewage pump
•
“15” represents the rated flow rate in cubic meters per hour (m³/h)
•
“30” represents the rated head in meters (m)
•
“P” indicates the pump body material is stainless steel (304, 316, etc.)
•
“B” indicates explosion-proof motor (absent for standard motor)
Understanding the model number helps customers select the correct pump for their specific application requirements. Different combinations of flow rate, head, material, and motor type are available to match diverse working conditions.
