GNWQ Series Three-Phase Dual Voltage Cutter Type Submersible Sewage Pump

3×220V/380V Universal | Industrial-Grade Anti-Clogging Cutting, High-Head Sewage Discharge Pump

HIDRO AQUA PUMP INDUSTRY CO.,LTD. has developed the GNWQ Series Three-Phase Dual Voltage Cutter Type Submersible Sewage Pump, specially customized for heavy-duty sewage discharge scenarios in Brazil. The entire series is compatible with 3×220V/380V three-phase dual voltage and 60Hz frequency, with power ranging from 0.37KW to 2.2KW and water outlet sizes covering 1.25 inches to 2.5 inches. Adopting a thickened all-cast iron body and an alloy cutting impeller design, it features four core capabilities: powerful cutting, anti-clogging discharge, high head and large flow rate, as well as corrosion resistance and durability. It can easily shred fibers, debris, sludge and other media, completely solving the problem of complex sewage discharge, and is an optimal heavy-duty solution for commercial, municipal, breeding and industrial sewage discharge.

Overcome Complex Sewage Discharge Pain Points for Stable Operation under Heavy-Duty Conditions

1. Solve the pain points of difficult three-phase voltage adaptation and high engineering construction costs

There are various specifications of three-phase power grids in Brazilian industrial and infrastructure sites, with mixed 220V and 380V voltages. Conventional water pumps have poor compatibility and complicated wiring modification. This series adopts a three-phase wide-voltage adaptive design, which can operate stably by directly connecting to the 3×220V/380V power grid without voltage regulating devices or circuit modification. It is fully adaptable to various engineering sites, significantly reducing the comprehensive costs of procurement, installation and operation & maintenance.

2. Solve the pain points of easy clogging by impurity sewage and frequent sewage discharge interruption

Septic tanks, farms and municipal sewage contain a large number of cloth strips, fibers, sludge and solid impurities, which can easily cause jamming, stalling and shutdown of ordinary submersible pumps. The GNWQ series is equipped with an alloy cutting impeller, which rotates at high speed to powerfully cut and shred all kinds of impurities. The wide flow channel design further prevents clogging, realizing continuous and uninterrupted sewage discharge and completely eliminating jamming failures.

3. Solve the pain points of insufficient sewage discharge head and weak long-distance transmission

In scenarios such as deep basement wells, long-distance pipe networks and high-drop sewage discharge, conventional water pumps suffer from rapid flow attenuation and insufficient head, failing to achieve efficient transmission. The hydraulic structure of this series is deeply optimized, with a maximum head of 28 meters and a maximum flow rate of 35m³/h. It delivers strong and stable power output, easily meeting the heavy-duty sewage discharge demands of high head, long distance and large flow rate.

4. Solve the pain points of easy body wear and short service life in harsh environments

Sewage working conditions are highly corrosive and abrasive, causing ordinary pump bodies to crack, leak and suffer motor damage easily. The whole machine adopts a thickened all-cast iron integrated body, high-strength wear-resistant materials and a fully sealed waterproof motor, which is impact-resistant, rust-resistant and wear-resistant. It can operate continuously when immersed in harsh sewage environments for a long time, with durability far exceeding that of ordinary submersible pumps and greatly reducing maintenance and replacement costs.

5. Solve the pain points of large vibration during heavy-duty operation and inconvenient installation & maintenance

Industrial sewage pumps are bulky with strong vibration during operation, leading to difficult installation in narrow well pits and high failure rates. This pump is equipped with a reinforced base and a portable lifting ring for convenient and stable installation and handling. Its compact body is suitable for narrow installation spaces such as various deep wells, sumps and septic tanks, and the modular structure design makes later inspection and maintenance simple and efficient.

Core Product Advantages

1. Full-range compatibility of three-phase dual voltage, universal for cross-border projects

Developed specifically for Brazilian three-phase power standards, it is compatible with 3×220V/380V dual voltage and 60Hz power frequency. It is suitable for all scenarios including industrial plants, municipal projects, breeding bases and commercial buildings, ready to use without voltage restrictions and with excellent universality.

2. Alloy cutting anti-clogging technology for unobstructed discharge of impurity sewage

The upgraded cutting impeller structure powerfully shreds solid impurities such as fibers, cloth strips and sludge. Combined with a large-diameter wide flow channel, it truly achieves no clogging and no jamming, adapts to various complex sewage media and doubles the sewage discharge efficiency.

3. High head and large flow rate with strong heavy-duty sewage discharge performance

The full series is equipped with multi-specification gradient configuration, covering a comprehensive range of head and flow rate to meet diverse demands from small-flow household sewage discharge to large-flow industrial transmission. It provides sufficient power and stable water pressure, enabling effortless high-drop and long-distance transmission.

4. All-cast iron heavy-duty body for corrosion resistance and long service life

The thickened cast iron pump body with precision sealing technology is waterproof, moisture-proof, impact-resistant, corrosion-resistant and wear-resistant. It can withstand harsh working conditions such as acid-base sewage and sludge abrasion, with a sturdy overall structure, long service life and lower operation & maintenance costs.

5. Fully sealed safety protection for more reliable and stable operation

Built-in motor overheating protection and waterproof sealing structure prevent water ingress, motor burnout and overload damage. It operates stably with low vibration, suitable for all-weather continuous operation, with comprehensive safety protection and reliable performance even under heavy-duty working conditions.

6. Full coverage of multi-specification and multi-caliber for accurate on-demand selection

With a full power range of 0.37KW-2.2KW and multi-caliber water outlets of 1.25-2.5 inches, it accurately matches different scenarios such as household basements, villa sewage discharge, farms, municipal pipe networks and small industries, balancing energy saving and high efficiency.

Wide Application Scenarios

It is suitable for septic tank sewage discharge, farm manure transportation, deep basement well drainage, construction site ponding treatment, municipal sewage pipe network discharge, garden landscape sewage circulation, factory impurity-containing wastewater transportation and rural reconstruction sewage discharge. It is an industrial-grade preferred equipment for complex impurity sewage discharge under three-phase power environments in Brazil and South America.
