In this blog post, we’re reviewing a Filling option in the form of the Express Scale ESP GB-32 Bagging Scale.
Express Scale ESP GB-32 Bagging Gross Weigher
The Express Scale ESP GB-32 Bagging Gross Weigher is a reliable and straightforward mechanical bagging scale designed for efficiently filling open-mouth bags with free-flowing granular products like corn, soybeans, pellets, and seeds. It’s a manual operator workhorse, perfect for medium-volume production.
The GB-32 can simultaneously weigh and fill up to 7 open-mouth bags/minute. The GB-32 is designed to fill 50-115 lb. open-mouth bags with circumferences larger than 32″. Fully mechanical, requiring no external power, the GB-32 is ideal for most free-flowing, non-dusty products.

Quick Comparison of GB-32 and JM-FF-ED from Express Scale models
Both the GB-32 and JM-FF-ED from Express Scale are gross weigh baggers, meaning they weigh the bag and contents together. However, they differ in their level of automation and operation. Here’s a comparison to help you choose the best one for your needs:
Operation:
- GB-32: Manual. The operator pulls a lever to open the gate and fill the bag. Weight is controlled by adjusting the filling time
- JM-FF-ED: Electronic. The scale automatically weighs the product and stops filling when the desired weight is reached
Speed:
- GB-32: 4-5 bags per minute
- JM-FF-ED: Up to 8 bags per minute, depending on bag weight and product flow
Accuracy:
- GB-32: +/- 4 ounces
- JM-FF-ED: +/- 4 ounces, based on product flow and consistency
Other features:
- GB-32: Simple and durable, requires minimal maintenance. Can be customized with different spout sizes and shapes
- JM-FF-ED: More features like dual position gravity gate for bulk or dribble feed, adjustable flow control, dust control connection, and programmable timers
Cost:
- GB-32: Less expensive
- JM-FF-ED: More expensive due to its electronic components and features
Summary:
- Choose the GB-32 if:
- You need a simple and affordable bagger
- You have low production volume
- You don’t mind manual operation
- Choose the JM-FF-ED if:
- You need higher speed and accuracy
- You want automation and more control over the filling process
