Guide to Pumping Jam

TS Pumps know how tricky it can be to find the perfect pump solution to fit your application. That’s why we’re here to offer a great range of pumps from a variety of high-quality suppliers, to suit your needs.

If you’re on the lookout for a pump that can handle thick substances like jam, even if they include small solids, our pumps are designed to handle these while still running smoothly and efficiently. In this article we will go through the best pumps for jam and similar applications.

 Why Is Pumping Jam Difficult?How to pump jam

Jam can be a tricky fluid to pump due to a few factors, firstly, it is quite viscous so needs a particular type of pump to transfer it. Secondly, jams often contain solids in suspension, such as fruit chunks or seeds, which can cause certain types of pumps to clog and also cause mechanical seals, which are fitted to the pump, to leak. Thirdly, due to the high sugar content and sticky nature of jam, seal faces in mechanically sealed pumps, can stick together when the pump is in standstill and rip apart and leak when the pump is put back into operation. Luckily, we have numerous options available to you to overcome these issues.

I Want to Pump Jam with Seeds, What type of Pump do I need?

If your food substance contains small solids within it such as fruit chunks or seeds, you will need to be aware of pumps that are robust enough to deal with them effectively. We have at our disposal numerous pump types which can be used for this type of application.

Sanitary lobe pumps are one of the most commonly used due to their ability to:                                  Pumping high viscosity applications

However, your perfect pump will be dependent on your specific application, therefore, a Peristaltic, AODD or Twin-Screw pump may be a better option for you. Speak to us today to discuss your specific application requirements and we will be more than happy to propose you the perfect pump for your application.

How do I Clean my Pump?

In order to make sure your pump, products & process are kept clean and sterilised correctly, we provide high quality stainless steel sanitary pumping equipment specifically design and built for use in the food industry (FDA Approved) which can be cleaned by a procedure called CIP (Clean In Place).

CIP is a process by which the pump & system are cleaned periodically by a caustic water solution at high temperature, typically 85ºC. The CIP process flushes the pump and system through to ensure that there is no fluid or substance left in the pump or system which can cause bacterial build up or blockages in the pump and system.

Pumps which are built for use in the food industry are also designed to have smooth internal surfaces, with no crevices, so there is no potential for bacterial build up which can then cause your produce to become unsuitable for consumption. Each pump type has their own cleaning requirements so once we have settled on the correct pump for your application, get in touch with us to discuss the recommended cleaning procedure.


How to Avoid Pump Clogging?

With substances like jam being thick and containing solids, pumps can easily become clogged if the product is left to settle and solidify within the pump or, if the pump is not sized correctly, solids can become lodged in the rotating assembly. However, at TS pumps we offer various options to battle this problem. One solution is the inclusion of a heated jacket, which can maintain the temperature of the product and stop it from solidifying within the pump. These jackets are welded on, covering the wetted parts and slowly push heated water through the external jacket of the pump. The heating fluid doesn’t come into contact with the process fluid so will not affect its consistency or rheology. We offer heating jackets on all of our sanitary pumps, be it Lobe, Centrifugal, Air Operated Diaphragm, Twin Screw and even Peristaltic.
