ZWII Series 2nd Generation Self-Priming Non-Clogging Sewage Pump

TheZWII Series is an upgraded 2nd generation self-priming pump featuring an advanced axial backflow external mixing structure. As a heavy-duty non clogging sewage pump, it is designed for horizontal surface installation without requiring a foot valve. This high-efficiency trash pump only needs initial water priming before startup for lifelong automatic self-priming operation. Optimized via CFD fluid dynamics for hydraulic efficiency, this self-priming pump delivers over 10% higher efficiency, reduced power consumption, stronger solids-passing capacity, and superior operational stability compared to standard models.

Key Features

• High Self-Priming Performance: As a reliable self-priming pump, its standard suction lift reaches 4–5 meters, eliminating the need for a foot valve and simplifying piping construction.

• Non-Clogging Operation: Equipped with a dual-vane / dual-channel impeller, this non clogging sewage pump easily passes large suspended solids, long fibers, heavy sludge, feces, and paper pulp slurry.

• Energy-Efficient Hydraulic Design: The upgraded 2nd generation hydraulic model of this trash pump lowers electricity consumption, making it ideal for continuous long-term duty.

• Simplified Maintenance: The horizontal mounting of this self-priming pump features an independent oil chamber protecting the mechanical seal, allowing easy disassembly and servicing.

• Multiple Material Options:Thisnon clogging sewage pump is available in Cast Iron (standard municipal sewage), 304 Stainless Steel, and 316 Stainless Steel (corrosive industrial media). Explosion-proof motors are optional.

Applications

• Municipal Engineering: Urban sewage discharge and stormwater drainage using this robust trash pump.

• Industrial Wastewater: Waste fluid handling in paper mills, textile plants, and food processing facilities via this non clogging sewage pump.

• Agriculture & Dredging: Livestock farm manure removal, river dredging, and pond desilting supported by this self-priming pump.

• Construction & Environmental: Dewatering at construction sites, sedimentation tank slurry transfer, and compact sewage pumping stations using this heavy-duty trash pump.
