ZW Self-Priming Sewage Pumps
The ZW Self-Priming Sewage Pump is a robust, energy-efficient solution engineered for demanding wastewater and industrial applications. Combining advanced self-priming technology with a non-clogging design, this pump excels in handling liquids containing large solids, fibrous materials, and abrasive sediments. Ideal for municipal sewage systems, mining, aquaculture, and chemical industries, it offers unmatched reliability and ease of maintenance.
Key Features
Self-Priming Excellence: Achieves a self-priming height of 5.5 meters without requiring a bottom valve or manual priming.
Non-Clogging Design: Open impeller and axial reflux flow path enable smooth passage of solids up to 60% of the outlet diameter and fibers 5x the outlet diameter.
Durable Construction:
◦ 304 Stainless Steel Shaft: Enhanced rust resistance for longevity in corrosive environments.
◦ Material Versatility: Available in cast iron, 201, 304, or 316 stainless steel for diverse fluid compatibility.
Energy Efficiency: Equipped with an internationally certified motor featuring pure copper coils, reducing energy consumption and operational heat.
Easy Installation: Standardized 6 kg flange design simplifies setup and integration.
Explosion-Proof Option: ATEX-compliant motors available for hazardous environments.
Technical Specifications
Flow Rate: 5–800 m³/h
Head: Up to 80 m
Suction Lift: ≤5 m
Temperature Range: -20°C to +100°C (extended to +280°C with special materials).
Power: 1.5–55 kW (motor options include Y-series asynchronous or explosion-proof variants).
Speed: 1450/2900 rpm (adjustable for optimized performance).
NPSH: 2.0–6.0 m.
Applications
Municipal & Industrial Wastewater: Treatment plants, sewage discharge, and sludge handling.
Mining & Construction: Dewatering, sediment removal, and slurry transport.
Aquaculture & Agriculture: Waste removal, river/pond management, and manure processing.
Chemical & Light Industries: Corrosive fluid transfer, paper mill effluents, and food processing wastewater.
Design & Construction
Hydraulic Innovation: Axial eddy current technology creates a vacuum for rapid priming and efficient discharge.
Open Impeller: Reduces clogging risk while maintaining high discharge capacity.
Seal System: Hard alloy mechanical seals ensure leak-free operation and extended service life.
Modular Structure: Separable motor and pump units simplify maintenance and part replacement.
Model Range Highlights
Compact Models: E.g., 25ZW8-15 (8 m³/h, 15 m head) for small-scale applications.
High-Capacity Models: E.g., 300ZW800-14 (800 m³/h, 14 m head) for large-volume industrial needs.
Customization: Explosion-proof, corrosion-resistant, and high-temperature configurations available.
Certifications & Advantages
Energy Efficiency: Exceeds standard self-priming pumps by 3–5% in efficiency.
ISO Compliance: Manufactured under stringent quality control standards.
Competitive Edge: Replaces submersible pumps (WQ/QW series) with superior dry-installation safety and lower maintenance costs.
Why Choose ZW Pumps?
Minimal Downtime: Easy-access design and replaceable components reduce servicing time.
Cost Savings: Energy-efficient motor and durable materials lower lifecycle expenses.
Versatility: Adapts to harsh fluids, including viscous, abrasive, and solid-laden media.
The ZW Self-Priming Sewage Pump redefines wastewater management with its blend of cutting-edge engineering, reliability, and adaptability, making it the preferred choice for industries worldwide.
