Discover what a sanitary pump is, how it works, and why it's crucial in industries like food, pharmaceutical, and chemical processing.
A sanitary pump is essential equipment for moving fluids in environments demanding hygiene and precision. From food processing to pharmaceutical applications, these pumps ensure clean and efficient operations. In this article, we'll explain what they are, how they function, and why they're indispensable in your industry.
What is a Sanitary Pump? Technical Definition
A sanitary pump is a device designed to transport fluids under strict hygienic conditions, preventing cross-contamination. It is constructed with materials like 316L stainless steel and PTFE, which resist corrosion and comply with standards such as FDA and EHEDG.
How Does a Sanitary Pump Work?
1. Intake Phase
Fluid enters the pump chamber as moving components (e.g., gears or lobes) separate, creating a partial vacuum.
2. Transport Phase
The moving elements trap the fluid in an enclosed space, eliminating backflow or contamination risks.
3. Discharge Phase
The fluid is expelled uniformly and precisely, ideal for applications requiring accuracy (e.g., pharmaceutical dosing).
Did you know? Sanitary pumps can handle fluids with varying viscosities, from water to thick syrups.
