1. Basic Information
This series of submersible sewage pumps covers a power range from 5.5kW to 200kW. The whole pump body is made of premium 304 and 316 stainless steel for strong anti-corrosion performance. Adopting integrated submersible structure, the pump is equipped with a built-in high-hardness alloy cutting device, full-copper durable motor and double-end mechanical seal. It is specially designed for river dredging, grey water discharge and various domestic and industrial sewage treatment projects.
2. Product Overview
Different from ordinary sewage pumps, this cutting-type submersible pump adds a sharp cutting impeller at the water inlet. It can automatically cut and crush weeds, cloth strips, fiber sundries and silt blocks mixed in sewage, effectively avoiding winding and blockage failures. The stainless steel housing adapts to corrosive water quality such as river brackish water, domestic grey water and mild industrial wastewater. With no need to build an independent pump house, the pump can be directly put into water for operation, featuring easy installation, low operating noise and stable long-term underwater working performance.
3. Core Competitive Advantages
First, powerful cutting and perfect anti-clogging performance. The high-strength alloy cutter head grinds all kinds of soft and hard sundries into fine particles, ensuring smooth sewage drainage without pipeline blockage. Second, excellent corrosion resistance. 304 and 316 stainless steel materials resist rust and chemical erosion, greatly extending service life compared with cast iron pumps. Third, reliable motor protection. Full copper motor provides stable power output; built-in thermal protection function prevents motor burnout caused by overload and dry running. Fourth, wide power coverage. Complete power specifications from 5.5kW to 200kW meet small domestic drainage, building sewage lifting and large municipal river dredging demands.
4. Application Scope
It is widely used for river channel silt cleaning, municipal sewage treatment, residential community grey water discharge, hotel and shopping mall sewage lifting, factory wastewater drainage, farmland sewage treatment and other harsh water environment occasions with many impurities and corrosive components.
5. Operation Notes
1. The pump must be completely immersed in water during formal operation; dry running without water is strictly prohibited to prevent motor damage. 2. Do not pump high-concentration strong acid and strong alkaline liquid beyond the corrosion resistance range of stainless steel material. 3. Regularly check the cable integrity and mechanical seal tightness to avoid water leakage into the motor cavity. 4. Long-term continuous operation under overload working conditions is not allowed. 5. Cut off the power supply completely before daily inspection and maintenance for operation safety.
