Graco bin systems are designed for high-viscosity materials that cannot be efficiently pumped using traditional methods. This includes peanut butter, frosting, creams, gels, lotions, tomato paste, syrups, heavy sauces, pharmaceutical ointments, and other products with extremely thick consistencies. The inflatable wiper plate allows these materials to be recovered cleanly with minimal waste.
Graco Bin Evacuation Systems
Graco Bin Evacuation System (BES)
Graco’s SaniForce Bin Evacuation Systems can evacuate medium to high viscosity products from 300 gallon (1136 liter) containers without diluting or heating the contents. Each system includes a pump ram with an inflatable seal that securely fits the container for evacuation rates up to 99%.
Common applications include the transfer of tomato paste, peanut butter, jams and jellies, icing and frosting, caramels, corn syrups, toothpaste, and more.
Product Overview
Key Features
-
- Up to 99% evacuation rate of medium to high viscosity materials without diluting or heating the contents.
- Superior alternative to manual scooping for improved food and employee safety.
- Automated controls remove unnecessary operator interaction and automate the unload process.
- FDA-compliant inflatable ram plate seal securely fits straight-sided and tapered drums with high evacuation rates and faster change-out of containers.
- Sanitary flange clamps allow quick disassembly for easy cleaning and sanitizing and minimal downtime.
- Save time and money in your facility by unloading materials up to 2,000,000 cps efficiently from 300-gallon (1,135 l) “bag-in-bin” containers – eliminating manual scooping or bin dumping.
- Complete bin unloading saves money and provides better process control while removing the need for costly booster pumps.

Theory of Operation
The Graco Bin Evacuation System is engineered to remove viscous and hard-to-pump materials directly from 300-gallon disposable or stainless bins. The system uses a pneumatic ram to lower a plate with wyper or inflatable seal, creating an airtight seal that wipes product from the container walls as it descends. This pressure forces material toward the pump inlet, where a Graco diaphragm, piston, or ram-mounted pump transfers product smoothly to downstream processes. Because the follower plate maintains constant contact and uniform pressure, the system eliminates trapped air pockets, reduces waste, and ensures continuous, controlled product flow. The result is up to 99% evacuation efficiency, cleaner changeovers, and precise handling of thick products such as peanut butter, creams, frostings, lotions, syrups, and other high-viscosity formulations.

Frequently Asked Questions
Graco Bin Evacuation Systems can recover up to 99% of the material, dramatically outperforming both manual scraping and standard pumping equipment. The inflatable plate forms a tight seal against the bin walls, pushing all product toward the pump inlet. This results in higher yield, faster changeovers, and reduced labor compared to typical industrial evacuation methods.
These systems offer major operational advantages:
- Reduced waste thanks to near-complete product evacuation
- Improved sanitation with FDA-compliant contact surfaces
- Faster changeovers for increased production uptime
- Lower operating costs by reducing manual labor and minimizing leftover product
- Consistent, air-free flow to downstream pumps and fillers
Together, these features make the system ideal for plants focused on efficiency, cleanliness, and yield.
