Fuller-Kinyon dry screw pumps

Heavy-duty Fuller-Kinyon™ dry screw pumps convey dry, free-flowing, pulverized materials anywhere a pipeline can be run.

Dry bulk materials are conveyed literally anywhere a pipeline can be run and to any number of delivery points. Distances of 4,500 feet (1,371 meters) are not uncommon.

The materials to be conveyed enter the hopper by gravity and are advanced through the barrel by the screw, discharging to the right or left, perpendicular to the screw centerline - unlike the H pump, which discharges straight ahead, in line with the screw centerline. The material is compacted as it is advanced. Its density is further increased in the space between the terminal flight of the screw and the face of the non-return valve to form a seal against the transport line pressure, thus preventing blowback.

The material then enters the discharge body, is fluidized by compressed air, and is conveyed into the transport line.

 

Fuller-Kinyon™ (FK) Pumps are constructed of cast iron and steel, and mounted on a cast iron base.

FK 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 and areas of this screw, along with other parts of the pump in direct contact with the material to be conveyed, are made of hardened, wear-resistant material and special hard surfacing where required.

The screw is directly coupled to the driving motor but can be v-belt driven.

Standard equipment on Type M 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.

Features

  • Dust-free pneumatic conveying
  • Increased capacity and performance
  • Low-cost, moderate duty operation
  • Ideal for hopper bottom car unloading

 

Fuller-Kinyon™ Kompact™ pumps are used to pneumatically convey dry pulverized materials such as Portland Cement, lime stone, bentonite, various ceramic clays and other materials at rates up to 3300 ft /hour (93 m /hour).

These pumps are ideally suited for intermittent operating applications with a limit of 20 psig conveying line pressure for the Kompact II Pump and 12 psig conveying line pressure for the 61V Kompact Pump. Various mechanical or manual loading and distribution methods can easily be replaced with this totally enclosed, dust-free pneumatic conveying system.

Thanks to a low silhouette and short profile, the pump is ideally suited for hopper-bottom car unloading. Fuller-Kinyon Kompact pumps require only a low-pressure, low-velocity air supply to efficiently meet its large throughput capacity.

Operation

Material to be discharged from a hopper bottom rail car enters the pump hopper through a boot lift rail car connection by gravity and is advanced through the barrel by a dynamically balanced impeller screw which is driven through a V-belt drive arrangement with an over-head mounted drive motor - discharging straight ahead, in line with the screw centerline - unlike the M pump, which discharges to the right or left, perpendicular to the screw centerline.

As the material advances through the barrel, it is compacted by the decreasing pitch of the screw flights. It is further compacted by by the space between the terminal flight of the screw and the discharge check valve disc to create the material seal. (This seal serves as the air lock to prevent the conveying air from blowing back through the barrel.)

The material then enters the mixing chamber, where it is fluidized by compressed air introduced through air nozzles. From there, the material and air mixture enter the transport pipe.
