Unibloc Food Grade Pump | Innovative Food Pump Technologies

Unibloc Pump has been a leader in food grade pump manufacturing for over 30 years. We pioneered the application of an all-stainless steel housing and base plate in our food pump. We were the first to cast one piece that includes flanges to minimize the number of parts that need FDA approval.

Innovation and engineering drive our product development and creatively solve challenges faced by the food processing, beverage, and pharmaceutical industries.

We offer a variety of precision engineered, high-quality food-grade gear pumps that fit a variety of applications in a multitude of industries. We are not the largest sanitary pump manufacturer out there, but we are the premier food product pump manufacturer with the most willing, ready and able staff to meet the toughest industry demands.

What is a Food Grade Pump?

A food product pump uses sanitary positive displacement (PD) technology to move product and fluid by repeatedly capturing a fixed volume and moving it mechanically through the system. This is a cyclic pumping action that can be driven by pistons, screws, gears, rollers, diaphragms, or vanes. 

Although there are quite a few food pump options, the majority can be placed into two categories: reciprocating and rotary. 

How a food pump works depends on the type of pump, application, and benefits required.

For example:  

  • Lobular pumps produce a lower flow rate and require a larger initial investment.
  • Progressing cavity pumps apply lower levels of shearing to the production medium. These pumps are better for processing fragile or viscous fluids. 
  • Double diaphragm pumps provide lower levels of fluid shearing but with greater clearance allowances. 
  • Centrifugal pumps are ideal for most beverage, oil, and batter processing operations.
  • Positive displacement pumps are the most versatile pump. They are used in a range of processing operations, like wine production, and the processing of thicker products and slurries such as pie fillings, baby food, cheese, cream, icing, mayonnaise, tomato sauces and pastes and similar substance types.

Food pumps must also comply with strict regulatory standards, including: 

  • FDA CFR 21.177 (safe elastomeric material use in pump construction)
  • 3A (material use, engineered with CIP and COP to minimize contamination) 
  • EHEDG (adds additional performance standards and CIP testing to 3A)

These standards help eliminate contamination in food and beverage processing. Compliance is essential in the manufacturing of food processing pumps.
