The GL201.123.1320 spiral centrifugal pump represents a significant advancement over traditional vertical pump designs, specifically engineered for high-volume, heavy-duty fluid management. Operating with a formidable 132KW motor, this flow-oriented equipment achieves a maximum flow rate of 1500 cubic meters per hour and a maximum head of up to 26 meters. The impeller operates at a precise 1485 revolutions per minute, ensuring continuous kinetic energy transfer even when processing dense, sludge-heavy fluid mediums. By integrating an innovative hanging plate design, this unit provides engineers and facility managers with multiple fixing methods, drastically reducing installation complexity and structural modification costs in existing pumping stations.
Industrial wastewater and municipal sewage networks frequently contain unpredictable debris that can halt operations. By significantly increasing the export dimensions and installing a larger impeller spacing, the spiral centrifugal design effectively eliminates the risk of internal blockages. It gently and continuously transports large solid particles and long fibrous materials without causing internal tangling or structural fatigue. This non-destructive conveying mechanism ensures maximum transportation efficiency, keeping your processing lines running smoothly without unexpected maintenance interventions or costly downtime.
Constructed to endure the most abrasive chemical environments, the core flow-passage components are cast from high-strength, wear-resistant alloys. A thick, industrial-grade anti-corrosive coating is applied to the heavy-duty metallic casing, providing a resilient, smooth barrier against acidic or alkaline wastewater. To maintain optimal operating temperatures during continuous heavy loads, the pump is equipped with a highly efficient dual-mode cooling system. The integrated water-cooled or oil-cooled jacket allows the motor to dissipate heat rapidly, ensuring safe operation whether deployed in a dry installation or fully submerged. Furthermore, a precision-engineered double mechanical seal creates an impenetrable barrier, protecting the internal motor components from fluid ingress and extending the overall lifespan of the equipment.
Due to its unique operational advantages and highly adaptable back fixed plate design, this submersible vertical spiral centrifugal pump serves as a critical infrastructure component across multiple demanding sectors. The ability to handle heavy, debris-laden fluids with a low-vibration, quiet operational profile makes it widely used in the following industries:
Municipal Engineering: Serves as the primary intake mechanism for urban sewage treatment plants, lifting pump stations, and rainwater management facilities. The pump easily processes mixed municipal waste, preventing gridlock during sudden storm surges and heavy rainfall events.
Industrial Sector: Essential for wastewater discharge in heavy processing industries such as papermaking, textiles, food production, and chemicals. The robust anti-corrosive coating and wide internal passage smoothly handle chemical runoff, fabric scraps, and organic byproducts without degradation.
Construction Field: Provides reliable domestic sewage management and basement drainage for high-rise buildings. Its compact vertical footprint and flexible hanging board installation make it ideal for confined subterranean utility rooms where space is at a premium.
Specialized Heavy-Duty Occasions: Frequently deployed for river dredging, flood control and drainage, and mine dewatering. The unit moves thick, abrasive sludge and grit-heavy water efficiently, protecting downstream filtration equipment.
In conclusion, the submersible vertical screw centrifugal pump with a back fixing plate is an efficient equipment solution engineered for the most punishing drainage environments. Before leaving the facility, every single unit undergoes rigorous dynamic and static balance testing, guaranteeing a remarkably low failure rate and reliable performance under extreme conditions. Its two core designs—the "spiral centrifugal impeller" and the "back fixing plate"—perfectly balance the three key requirements of no blockage, high head, and easy maintenance. This synergy makes it the preferred, long-term solution for modern sewage lifting systems requiring absolute operational certainty.
