Piston FillersPiston Filler Animation

There are two types of piston fillers that are available namely check valve and rotary valve.

 

Check Valve Piston Filling Machines

 

A check valve piston filler works on a check valve principle that opens the infeed valve on the draw stroke then forces the draw side check valve closed while opening the discharge valve on the dispense stroke as can be seen clearly by the animation to the right.

The big advantage of a check valve filling system is it can self prime and draw product directly from a drum or other container without need for pumping or otherwise transferring product to another vessle. Simply drop the hose into the drum, adjust the fill volume and start filling product with excellent accuracy of +/- one half percent.

Check valve piston fillers work well with most any free flowing liquid (meaning it pours easily), but does not work well on thicker products or products with particulates in them as they can foul the valves.

 

Check valve piston filling machines are available as tabletop models, inline systems or rotary high speed models. Please give us a call so we can review your application.

 

 

Rotary Valve Piston FillerRotary Valve Piston Filler Animation

Rotary valve piston filling machines can do all of the "hard" jobs like filling pastes and products with particulates such as cottage cheese, potato salads, peanut butter, salsas and many other chunky products.

 

The concept is actually rather simple in that the hopper flood feeds the rotary valve which connects between the hopper and cylinder on the draw stroke and then flips ninty degrees between the cylinder and discharge tube on the dispense stroke, as can be seen in the animation on the right. Because the rotary valve can be hollowed out, large particles of up to one half inch (sometimes larger) can pass through without damage.

 

Rotary valve piston filling systems are available as benchtop, automatic inline, and rotary high speed systems and can be sized for your range of filling needs up to a 10:1 ratio and maintain its amazing +/- one half percent accuracy.

Automatic Rotary Valve Piston Filler 

Fill Master Automatic Inline Rotary Valve Piston Fillers

Automatic rotary valve piston fillers are available in models of 2, 4, 6, 8, and 10 head inline machines.  Standard hopper sizes range from 10 to 50 gallon, but all are upgradeable for up to 100 gallon.

Many options are available including: hopper lid, level control, diving nozzle mechanism, product agitator, heated hopper, heated valve block, Teflon product contact parts, wash down motor and controls, positive cut-off valves (of several types).

A typical automatic machine includes a 10 foot stainless steel constructed conveyor, bottle indexing system, and all pneumatic logic, making it very attractive for total washdown or hazardous environments (with replacement of conveyor motor for washdown motor, or air drive motor for hazardous locations).

Call today and our sales engineers will help advise you on the correct machine and options to meet your production requirements.

High Speed Rotary Piston FillersHigh Speed Rotary Piston Filler with Rotary Valves

For higher speed requirements it is necessary to move away from the inline piston filling systems and instead to rotary filling machines. In this format, filling systems can be designed for an almost unlimited number of production requirements.

To learn more about our high speed piston fillers please go to our rotary filling page.

Combination-High-Speed-Filler-CapperOftentimes high speed systems are combined into a sort of monoblock often called dual-modal, or tri-modal where filling and capping (dual) and rinsing (tri) are built on a single platform. To the left is an example of a dual-modal system with a rotary piston filler and capper.
