Marine CF Centrifugal Grinder Pump

Category

About product

The CF-type pump is a marine horizontal centrifugal pump specifically designed for shipboard domestic sewage systems. It integrates both maceration and transfer functions. Its primary role is to crush soft debris found in domestic wastewater during vessel operation and discharge it efficiently using centrifugal force. Our CF macerator pump meets all relevant technical standards and is also suitable for crushing low-temperature solidified heavy fuel oil, making it easier for injection and subsequent handling.

  • Type: Horizontal, Single-Stage, Centrifugal
  • Main Function: Maceration and transfer of soft debris in domestic sewage with temperatures ≤85°C
  • Maceration Performance: Recirculating maceration ensures particle size ≤5mm; anti-clogging and easy discharge
  • Applications: Shipboard domestic sewage treatment systems, low-temperature solidified heavy fuel oil crushing and injection
  • Material Options: Primarily cast iron, with optional corrosion-resistant materials such as stainless steel
  • Operation Mode: Motor-driven, horizontal installation, compact structure with excellent vibration resistance

Functions of CF Marine Horizontal Centrifugal Pump

  1. Maceration and Transfer of Soft Materials in Domestic Sewage: Designed for processing shipboard domestic sewage with temperatures not exceeding 85°C, this pump effectively macerates soft debris such as tissue paper, fabric scraps, and kitchen waste. After recirculating maceration, the maximum particle size is reduced to ≤5mm, facilitating smooth discharge or centralized treatment.
  2. Crushing of Solidified Heavy Fuel Oil: For ship operations involving low-temperature solidified heavy fuel oil, the CF pump is capable of cutting and breaking the medium into a pumpable state. This function is especially useful for heavy oil recovery systems and marine fuel pre-treatment units.

Marine CF Centrifugal Grinder Pump – Key Features

  • Horizontal Single-Stage Centrifugal Design: Designed with a horizontal layout and single-stage centrifugal mechanism, this pump features a compact structure and low center of gravity. It is ideal for confined shipboard spaces and provides stable operation with excellent resistance to vibration and tilt, ensuring long-term reliability under complex marine conditions.
  • Integrated High-Efficiency Grinding Mechanism: Equipped with a built-in high-strength alloy cutter disk and shredding ring, the pump offers superior cutting performance. It effectively grinds soft contaminants such as toilet paper, food scraps, and fabric residues found in domestic sewage, reducing clogging risk and ensuring smooth discharge—particularly suitable for high-frequency or heavy-duty shipboard sewage systems.
  • Optional Sealing Systems: To suit various marine conditions and media types, the pump offers a choice between mechanical seals and packing seals. Both sealing options deliver outstanding leakage prevention, pressure resistance, and corrosion protection, enabling long-term, leak-free operation in humid, corrosive environments and meeting stringent marine environmental and safety standards.
  • Customizable Corrosion-Resistant Pump Materials: The standard pump body is made of grey cast iron, suitable for general wastewater treatment. For highly corrosive or sanitary-critical applications, optional materials such as 304/316 stainless steel, ductile iron, or bronze are available, enhancing durability and adaptability to diverse fluid conditions including seawater or oily waste.
