Marine Copper Sewage Pump

I. Product Overview

The marine copper sewage pump is a core key equipment of the ship's sewage treatment and discharge system, specially designed for the transportation and treatment of corrosive and impurity-containing media such as ship domestic sewage, bilge sewage and oily sewage. Its core working principle is that the motor drives the impeller to rotate at high speed (or gear meshing), and uses centrifugal force (or volume change) to generate negative pressure, realizing the smooth suction, pressure boosting and continuous transportation of sewage. Relying on the excellent corrosion resistance, sewage erosion resistance and good chemical stability of brass materials, the product has obtained certifications from mainstream classification societies such as CCS, ABS and BV, and is widely used in 500-100000 ton-class ocean-going cargo ships, ro-ro passenger ships, inland river cargo ships, fishing boats and offshore engineering platforms. It is a core equipment to ensure the compliant discharge of ship sewage and maintain the ship's environment and navigation safety.

III. Core Advantages

Super Strong Corrosion Resistance: Brass/bronze materials can effectively resist the erosion of high salt spray and high humidity marine environment, and at the same time tolerate the long-term corrosion of oil stains, acid and alkali trace impurities in sewage. It is not easy to rust and scale, and its service life is more than 100% longer than that of cast iron sewage pumps.

Excellent Sewage Adaptability: Adopts open/semi-open copper impeller design with wide flow channels, which can effectively avoid winding and clogging of impurities such as fibers and sediment; Copper material has strong chemical stability, does not pollute sewage, does not affect the subsequent sewage treatment effect, and ensures compliant discharge.

Stable and Reliable Operation: Precisely processed copper transmission components have uniform operation gaps, no pulsation during operation, constant flow and pressure, and can realize stable and continuous sewage transportation; Equipped with corrosion-resistant seals to achieve leak-free transportation, eliminating sewage leakage and pollution of the ship's environment.

IV. Typical Application Scenarios

Ship Domestic Sewage Transportation: Transports crew domestic sewage from the sewage collection tank to the ship's sewage treatment device, provides stable feeding to ensure sewage purification treatment, and avoids direct discharge of domestic sewage polluting the marine environment.

Bilge Sewage Discharge: Discharges oily sewage, rainwater and equipment leakage sewage accumulated in the ship's bilge, keeps the bilge dry, prevents sewage from corroding the cabin structure, and ensures ship stability and navigation safety.

Sewage Treatment System Matching: As the feed pump/discharge pump of the ship's sewage treatment equipment, it transports the sewage to be treated to the treatment unit, or transports the treated up-to-standard sewage to the discharge port, ensuring the continuous operation of the sewage treatment system.
