The CTS – H Self-Priming Centrifugal Pump range is suitable for a wide variety of applications where suction lift is required or for pumping highly aerated fluids within the industrial, food, beverage and pharmaceutical industries.CTS – H Self-Priming Centrifugal Pump is used in a variety of hygienic applications, ideal for transferring or offloading various ingredients and products. As they can be ATEX rated they can also be used for hazardous zones.
In their Hygienic form (CTS H), they 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 however be used for pressure boosting, dispensing, loading and offloading, tank cleaning, batching & metering, when used in conjunction with some of our wide range of control accessories.

The CTS units are available with either 2 pole (high head applications) or 4 pole (low head applications) motors to provide a wide envelope of capacity, detailed as follows:
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 lowering 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 crystalize. An Oil Pot is connected to the seal chamber and continually lubricates 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 CTHs 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 of the lubricating fluid. The max pressure of the quench circuit is 0.5 bar and it is recommended to install a thermo-syphon circulation into the quench circuit.
