FAQ – FILLERS
What’s the difference between a volumetric filler and an overflow filler?
A volumetric (piston) filler dispenses a fixed, pre-set volume into each container. An overflow filler fills to a consistent level regardless of small differences in bottle volume, which keeps the visible fill line uniform across a batch — important for retail-facing liquid products.
How do I choose between a piston filler and a fill-by-weight system?
Choose piston filling when the product’s density is consistent and a set volume per container is what matters. Choose fill-by-weight when density varies (common with foamy, viscous, or particulate heavy products) and the actual net weight per container is the number that must be controlled and verified.
Can these fillers handle foamy or viscous products?
Yes. The Metering Pump Liquid Filler (MP90NG-CA) is built specifically for foamy products using profiled sub-surface fills, and the Precision Piston Filler (PF20-CA) handles highly viscous liquids with the same sub surface, splash-reducing approach.
Can a semi-automatic filler be upgraded to fully automatic later?
Yes. The Semi Automatic Overflow Filler (LF90ST-C/PD) is specifically designed to be upgraded to the fully automatic LF90CA-C/PD configuration as production volume grows, so you don’t need to replace the machine outright.
Are SPM fillers built in Canada?
Yes. All SPM filling equipment is designed and built in Canada, supporting shorter lead times and local parts and service.
