Sanitary Pump Guide
What is a Sanitary Pump?
The most important factor to consider when looking to purchase or install a Sanitary Pump is to check it is FDA certified, which will be present on the pump’s seals. Additionally, the pump should be made from 316 polished Stainless Steel with smooth internals to ensure there is no surface for the fluid to sit inside. The smooth surface of a higher grade material ensures the pump’s internals have no ‘dead’ space that will prevent media from draining away. If there is dead space present, these spaces will allow bacteria to build up if it’s left in the housing.
How do I check if I have a Sanitary Pump?
You can check if your pump is sanitary by asking to see a copy of the certification and ensuring it is made from polished stainless steel. The pump company you deal with at the time of order should be able to advise you on these specifications, but be warned, it’s common to be sold a basic water pump that is not food grade.
It is important to note that any pump can incorporate an FDA approved seal, but this doesn’t mean that the pump itself is sanitary. The whole pump needs to meet sanitary standards, including the steel grade, as previously mentioned.

We’ll need some information from you, including the product being pumped, head pressure, flow and temperature. After a few more details, we’ll be able to help advise you on what kind of pump you’ll need for your specific operation.
Is there a best practice when using Sanitary Pumps to ensure we keep the process clean?
Yes! When installing and designing your process for the pump, it is important to consider how you’re going to clean the pump and pipework out after use. The most common way of doing this is by pumping Caustic through the system this is called CIP. This relates back to the beginning of the article when we spoke about how it is important to ensure your pump has smooth internals, which ensures that the Caustic can get into every area of the pump head and then come back out of the outlet.
Sanitary Pump Case Study
Here’s an example of how a Sanitary Pump could be used.
We recently worked with a large Brewery in the north of Scotland. TS Pumps were approached regarding this job due to a strong working relationship, built previously when working with the on-site engineering team to find multiple pumping solutions for a past problem.
Fluid: Beer and Caustic fluid for CIP
Viscosity: 50 CPS
Flow Rate: 25 m3/HR
Temperature: Room Temp
Head Pressure: 2 Bar Roughly
The Sanitary Pump solution offered by TS Pumps:
Pump Type: CTH DF-40
