The WQX Series represents a paradigm shift in submersible pump technology, integrating aerospace-grade materials with hydrodynamic innovation to deliver uncompromising reliability in sewage, industrial effluent, and high-solids fluid transfer.
Core Technological Superiority
1. Ultra-Durable Stainless Steel Construction
Material Integrity: 304/316L stainless steel body (model-specific) provides exceptional corrosion resistance against H₂S, chlorides, and acidic effluents.
Investment Casting Process: Precision-machined surfaces (Ra ≤ 3.2μm) ensure perfect sealing geometry and hydraulic efficiency.
2. Powerplant Excellence: 100% Pure Copper Motor System
Oxygen-Free Copper Windings: Enamel-coated pure copper conductors minimize I²R losses, achieving 92% motor efficiency (IE3 standard).
Thermal Defense System: Embedded Klixon thermal protectors trigger instant shutdown at 130°C ±5°C, preventing burnout during dry-run or jam events.
Magnetic Core Optimization: Cold-rolled silicon steel laminations (0.35mm thickness) reduce eddy currents by 40% versus conventional designs.
3. Tribological Mastery: Bearing & Sealing Ecosystem
SKF-Grade Bearings: Angular contact bearings pre-lubricated with Mobil SHC 634 synthetic grease sustain 20,000+ hours at 3600 RPM.
Triple-Seal Containment:
Primary seal: Silicon carbide/tungsten carbide mechanical face seal
Secondary: HNBR lip seal with anti-clogging springs
Tertiary: Labyrinth particle exclusion system
Aging Resistance: Fluorocarbon elastomers maintain elasticity across -30°C to 180°C operating range.
Performance Engineering: Beyond Specifications
Hydrodynamic Profile
Impeller Dynamics: Vortex-type open impeller (S.G. iron/duplex SS) handles 65mm spherical solids without clogging.
Hydraulic Balance: Back-vane pressure compensation eliminates axial thrust, reducing bearing load by 70%.
Operational Intelligence
Auto-Clean Function: Reverse rotation capability clears fibrous entanglements (patent pending).
VFD Readiness: All models compatible with variable frequency drives for flow modulation ±20% of BEP.
Technical Specifications: Engineered Precision
