How to Adjust Portion Size on Your 1-oz Stainless Steel Pump


Precise portion control can help foodservice operations control food costs and ensure flavor consistency throughout the day and even across multiple restaurants. Server Products stainless steel pumps include gauging collars, which allow you to choose your portion size in 1/8-oz increments. Our stainless steel pumps work with a variety of food products from syrups and dessert toppings to condiments and sauces, and come in three max-portion styles to fit your dispensing needs: 1-oz, 1 1/4-oz, and 2-oz.

Follow these simple steps to adjust your portion size using a 1-oz stainless steel pump:

Remove the plunger
