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.

Sanitary Pump Range

 

Within the Sanitary Pump market, you have a variety of options for the different types of process pumps available. Below is a list of the most common variations of Sanitary Pump, along with the typical applications. TS Pumps supply all of the Sanitary Pumps below, so read through the options and get in contact with us today for a quote.

The pumps and the main advantage of each:

 

Sanitary Centrifugal Pump: Suitable for high flow applications with a flooded suction on media with a consistency similar to water, less than 400 cps.

View the TS Pumps range of Hygienic Centrifugal Pumps, included within the range is the Hygienic Centrifugal Pump and the Hygienic Self Priming Centrifugal Pump.

Sanitary Diaphragm Pump: Suitable for plug and play with flexibility of flows and head without having a negative effect on the pump. Our Sanitary Diaphragm Pumps are self-priming up to 9 metres wetted and can run dry.

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.
