Q. How should fill heads be set up for optimum filling?


 Q. Why do you use double acting positive displacement pumps in your volumetric machines?

Our volumetric pumps are flooded with product on both sides of the piston; this means that there is no "dry side" to our pumps which increases seal and cylinder life and the speed of fill. When filling a gallon can, for example, 1/2 gallon is filled on the forward stroke and 1/2 gallon on the return stroke. Not having a prime cycle means that the pumps are ready to fill the next container the moment they have finished the previous one.

Check out competitors single acting pumps in the field! Chances are high that you will see product dripping out of the dry side of the piston, this is product which should be going into your customers cans!

We are still servicing 35 year old volumetric double acting pumps ( which originated from the UK ) these machines are built to last!


Solution: Filling Machine Would Not Start

Net Weight filling machine would not start filling, but upon checking, it was discovered that the fill head was open. Under settings in "Fill heads manual", the head was set to open. Once the head was changed to close, the machine operated perfectly.

Solution: Weights drifting down after using check weight options

Especially relevant when filling plastic five gallon pails, ensure that the lifter plates are raised sufficiently to raise not only the sides of the pails, but also the underside at the center point. Look down the conveyor to see if there is clearance at both the sides, but also at the center of the pail. If it is not, it is possible for the pail base to expand after being filled, then touching the conveyor and giving a false weight reading as it does.

Solution: Load Cell Weight Reading Issues

Solution: Lid Dropper Lids Knocked Off Press Issues

Lids placed trailing on the cans (instead of leading) are more difficult for the star-wheels to center. If the star-wheels are slightly loose against the cans, they will typically push a leading lid back into the chime but will not fully center a trailing lid. This results in the lid being slightly raised and typically being knocked off by the first roller of the lid press.

To remedy, center a can underneath the star-wheels then check the gap by pushing the can against one of the star-wheels and measuring the gap on the other side – it should be no more than 1/16” from one side to the other. 

Star-wheels with slots can be difficult to accurately adjust – we offer star-wheels for individual cans (with holes instead of slots) for more accurate centering; please send 2 sample cans and lids to our customer service department for accurate sizing and quoting.

Solution: Fill Head Setup

If fill heads will not close despite no changes being made to the program or recipe, check the PSI. Fill heads need a minimum of 60 PSI in order to function correctly.
