Fuller-Kinyon™ Pumps offer you over 75 years of history to the materials handling industry. The following brief history of the F-K Pump will give you an idea of the dependability of this product, and of the designs that are available.

• First developed 1919 - 1926
• Type 'h' pump, developed in 1935 with over 12,000 sold
• Kompact pump, developed in 1961with over 1,000 sold
• Type 'm' pump, developed in 1976 with over 1,600 sold
• Z-flap conversion kit  (1984), which modifies existing 'h' pumps by adding discharge end bearing
• Kompact II pump, developed in 2001 with 7 sold and in operation

So what is an F-K Pump?

• It is a screw type volumetric line charger
• It uses a material seal
• It provides continuous/semi-continuous operation
• The F-K pump is used in a "dual" or "two-phase" conveying system
• It is a device used to introduce material into a vacuum or pressure conveying system.

How does it work?

The F-K Pump uses the conveyed material to create the seal between the inlet and the outlet pressure differential. The decreasing pitch flight compresses the conveyed product to create this seal. The graphic below shows how this occurs inside the pump.

What types of products can it handle?

• dry, free flowing ,fluidizable materials
• typical analysis
  100% < 50 mesh
  70% < 100 mesh
  60% < 200 mesh
  45% < 325 mesh
• long distance conveying, over 5000 ft  (1500 m)
• high capacity conveying, up to 17,700 cfh (500 cmh), e.g.. 400 tph @ 45 lb./cu.ft.
• low headroom installations, i.e. railcar unloading (bottom discharge)
• many different types of materials (click to see a list of materials handled)

The "M" Type F-K Pump design comes standard with our 3-piece screw design. Some of the advantages of this design are:

• Split Screw Design
• Reduced Maintenance
• Increased Bearing Life
