Pumping Optional Features

Many options are available to customize your machine to better suit production needs.  Various products require specific design features and Doering has the knowledge and experience to assist you in formulating the appropriate machine to fit your pumping needs. 

  • Augers: 304 or 316 SS, Dairy Metal, or HRS.  Solid or Hollow flite for circulation of heating / cooling fluids.
  • Transition and Extruding Heads:  304 or 316 SS, Plain or jacketed for circulation of heating/cooling fluids.
  • Main Frame:  Low, regular or special profile designed to fit application.  304 or 316 SS construction.  Floor or caster mounted with brakes, leveling bolts or other special mounting.  With or without “Swing Away” pump or “Swing Up” pump frame.
  • Pump Frame:  pump frames are available with a  variety of features.  Up Swinging pump frames move the pump and motor together upwards to a horizontal position to allow for easy access to Transition Head and Augers.  These are available with or without pneumatic assistance. 
  • Swing Away Pump Frame: swing aside from extruder for easy access to Augers and Transition Head.
  • Heating/Cooling Systems:  for controlling temperatures of augers, power feed roll, extruding heads, transition heads, pumps and piping.  Either self contained heating and circulating systems or systems using customer’s existing hot or cold fluid systems.
  • Bridge Breakers:  for a few products bridge breakers may be employed in the hopper to prevent product bridging over the augers.  These variable speed breakers can prevent bridging of the product without overworking.
  • Grinder Plates: to reduce particulate size in product.
  • Power Feed Devices: single or double roll, with or without fins.
  • Hopper Trays/Feed Chutes/Hoppers: custom designed to meet the needs of your application.
  • Bucket Elevators: mechanical bucket elevators allow filling of hopper without strain to machine operator.  Available with or without heating/cooling jacketed system. 
  • Extrusion Heads: custom designed to meet product needs Extrusion Heads can be made from a variety of materials including Delrin, Stainless Steel, Teflon and others.  Heads are engineered to customer specifications for product shape and size and are available with or without cutters to control product length or allow for continuous extrusion.
  • Motors: Doering machinery utilizes a variety of motors for different applications.  Typically all motors are Hollow Shaft, Washdown Duty, Inverter Duty, and Painted with Stainless Steel Paint.  Avoiding chains and couplings allows for a much sleeker, lower maintenance machine.
  • Controls and Control Panels: A wide variety of electrical components are available to the customer.  NEMA 4 Stainless or Fiberglass enclosures and pushbutton stations. Variable Frequency Drive selection from a variety of manufacturers.  As well as any number of product sensors, pressure sensors, timers and other process control components are available for your application.
  • Pumps:  Wide variety of manufacturers and types of pumps are utilized in our pumping systems.  316 SS, Dairy Metal, or other sanitary metals.  All standard sizes and inlets/outlets including Acme threads, Tri-Clamps, IPS, and rectangular inlets.
  • Seals:  “O” Ring Seals available on Augers, heads and Power Feed Rolls to prevent product leakage.  A variety of materials are available including Buna-N, Teflon, and ……
  • Finishes:  Framework and components are available in a variety of finishes including Glass Beaded, Hand Polished, Teflon Coated, Electropolished, or Passivated.
