The Carlsen Screw Pump System is the world’s most commonly used pneumatic conveying system on board of Self-Discharging Cement Carriers (SDCC). An FK pump (Fuller-Kinyon Pump) or also named Material Handling Pump or Screw Pump, is installed in a tunnel underneath the fluidized floor in the cargo holds. Cement or other powdered material is then conveyed through the discharge pipelines to the onshore storage facility. More than 15.000 pumps are supplied already, the Screw Pump System is a proven solution for unloading SDCC’s. The screw pumps can reach capacities up to 700 tph and conveying distances up to 1500 meters.
Introduced in 1926, the Fuller-Kinyon (FK) pump technology provides lower power consumption, lower maintenance needs, and increased efficiency, flexibility, and reliability over other pneumatic systems. The FK pump is ideal for conveying fine powders without risk of blowback. A material seal is formed when product is compacted in the barrel and forced against the counterweighted flapper valve preventing convey-air leakage back through the screw. Only one moving part means less maintenance and high reliability in the most demanding environments. Parts can be replaced without removing the pump from service. Recent technological improvements on the FK pump include the use of high-wear pump screws, and the pneumatic flap controller for optimization of throughput of the system.
The Screw Pump System is best suitable for new ships, as the pumps have to be positioned below the fluidized floor of the holds. The system is simple and reliable although is energy consumption may be higher than other systems of board SDCC. In that regard the Carlsen E3-Cargo System is the most energy efficient bulk material handling system on board of SDCC, for more information check or blog post “Energy efficiency for bulk materials handling on board of self-discharging cement carriers” here.
The Fuller-Kinyon Pumps are also used, besides on board of SDCC, to convey dry, free-flowing, pulverized materials from grinding mills, transfer materials from silo to silo, transfer dust from collectors, and load and unload railcars, ships and barges. The materials are conveyed literally anywhere a pipeline can be run and to any number of delivery points.
Fuller-Kinyon Pumps are constructed of cast iron and steel, and mounted on a cast iron base. The pumps are equipped with ball bearings that support a pump screw at both ends to help provide a smooth, balanced operation. The screw is dynamically balanced. Areas of the screw, and other parts of the pump that are in direct contact with the material to be conveyed, are made of hardened, wear-resistant material and special hard surfacing. The screw is directly coupled to the driving motor but can be v-belt driven.
Standard equipment on the pumps includes a pressurized seal and bearing assembly that extends the service life of the discharge seals by preventing the material being handled from entering the bearing area. Each pump system includes the pump, drive motor and compressed air source.
