Hygienic Self Priming Centrifugal Pump

Our Hygienic Self Priming Centrifugal Pump (CTS H) is suitable for a wide variety of applications where a suction lift is required, or for pumping highly aerated fluids within the Industrial, Food, Beverage and Pharmaceutical industries. The CTS H Self Priming Centrifugal Pump is used in various hygienic applications, ideal for transferring or offloading multiple ingredients and products. As they can be ATEX rated, they can also be used for hazardous zones.

In their Hygienic form (CTS H), our Self Priming Centrifugal Pumps are ideally suited for the transfer or offloading of various ingredients and products like edible oil, flavourings, alcohol, dairy products and juice. There are also many auxiliary applications such as the transfer of CIP liquids, detergents and water. Rather than typically being used for tank-to-tank transfer applications, they can also be used for pressure boosting, dispensing, loading and offloading, tank cleaning, batching and metering, when used in conjunction with some of our control accessories.

Sealing Options for our Hygienic Self Priming Centrifugal Pump

Standard Single Mechanical Seals are provided with a range of face materials, Ceramic / Graphite / SiC and O-Rings are available in EPDM / FKM / FFKM or FEP or alternatively, the seal can be provided with an OP-Ring (Square O-Ring). This increases the friction between the O-Ring and the back casing and therefore lowers the chances of the static parts of the seal from sticking together.

Lubricated & Externally Quenched Mechanical Seals can also be provided upon request and are ideally used when there is the potential for dry running or where there is a chance for the product to solidify or crystalise.

An oil pot is connected to the seal chamber and continually lubricates the seal during operation. SAE Grade 20 oil is recommended however you must use a fluid compatible with the pumped medium and materials within the pump. As an alternative, the CTH S can be supplied with ports to facilitate an external quench system.

This provides the added benefit of removing heat build-up from the seal face and doesn’t require changing the lubricating fluid. The max pressure of the quench circuit is 0.5 Bar and it’s recommended to install a thermo-syphon circulation into the quench circuit.
