CTX centrifugal pumps are reliable and efficient pumps designed to minimize downtime and ensure excellent performance. They provide long-lasting and trouble-free operation, are easy to clean, and suitable for pumping liquids with solid inclusions. They are equipped with a high-efficiency, robustly constructed open impeller. Designed and optimized to ensure the highest pump energy efficiency and the ability to pump in a wide range of operating conditions.
Thanks to their modular design, these centrifugal pumps can be adapted to various applications and installation conditions – they are available in 3 versions: industrial (CTX I), hygienic (CTX H) and self-priming (CTX S).
CTX I centrifugal pumps can be used, among others, in the food, dairy, chemical and pharmaceutical industries.

| 2. Variety of connections DIN 11851, DIN 32676. Other connection types on request. |
|
| 3. Hygienic mechanical seal system Single or double mechanical seal. |
|
| 4. Optimized casing and impeller design The shape of the pump chamber and impeller are the result of advanced multidimensional analysis and numerous performance tests. Both of these elements have been designed and optimized to ensure the highest energy efficiency of the pump. |
The two main parts of a centrifugal pump are the impeller with vanes and the pump casing. Liquid enters the pump through the suction connection near the center of the rapidly rotating impeller. The liquid on the suction side moves along the impeller axis and, due to the centrifugal force generated by the vanes, is thrown radially outwards into a chamber in the casing. The casing gradually expands in a spiral towards the discharge nozzle, which reduces the liquid velocity and thus increases the pressure (diffuser effect). At the same time, as the liquid is thrown radially outwards by the impeller towards the discharge connection due to centrifugal force, the pressure at the center of the impeller drops, enhancing the suction effect of the liquid into the pump, which enables a continuous liquid transfer process.

Hygienic mechanical seal system |
|
| Single mechanical seal
The mechanical seal spring is not in contact with the pumped liquid, which makes the internal pump chamber fully washable. |
![]() |
| Double mechanical seal
Used when the liquid and its vapors pose a threat to the operator or the environment and must be contained, when aggressive media are used at high pressures or temperatures, and also for many polymerizing and crystallizing media. |

| Self-Priming Centrifugal Pumps | CTX S series
Thanks to the self-priming capability, the CTX-S series pump can be used in situations where it is necessary to lift liquid from a level below the pump. Since the standard CTX pump is not able to create a vacuum, a simple modification allows the pump to lift liquid from a height of up to 5 m. After the initial priming, the return pipe will recirculate liquid from the discharge side of the pump to ensure the liquid ring is maintained inside the pump. The self-priming option is easy to adapt to existing pumps by replacing the front cover and adding a vent screw. |

| Built-in frequency converter
The simplest and most flexible way to change the pump’s operating parameters. The inverter also provides overload protection and acts as a soft starter. |
![]() |
| Inducer
The inducer increases the inlet pressure, thus lowering the pump’s NPSHr. This option is very easy to install even on existing pumps – to install it, simply screw the inducer to the impeller. |
