Operation principle

The two main parts of a centrifugal pump are the impeller with vanes and the pump casing. Liquid enters the pump through the suction port 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 port 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.

Construction

Modular design The modular design of the CTX series centrifugal pumps provides greater flexibility in adapting to different operating conditions. This also means greater pump versatility and quick and easy upgradeability. The interchangeability of parts between different pump types and sizes makes pump operation and maintenance cheaper and easier. Compared to their counterparts in the CTI and CTH range – Tapflo CTX-I and CTX-H centrifugal pumps can achieve higher pressures and are available in larger sizes, providing a more versatile flow range.
	Open impeller CTX series pumps have an open impeller with a robust design, high efficiency and low Net Positive Suction Head required (NPSHr). CTX series pumps with an open impeller are both easy to clean and suitable for pumping liquids containing solids. Adapting the performance of CTX pumps to specific operating points or ranges can be done by machining impellers at constant speeds or by adjusting the pump speed at constant impeller diameters.
Hygienic mechanical seal arrangement
Single mechanical seal The mechanical seal spring is not in contact with the pumped liquid, making the internal pump chamber fully washable.
Double mechanical seal Used when the liquid and its vapors pose a hazard to the operator or the environment and must be contained, when aggressive media are used at high pressures or temperatures, and for many polymerizing and crystallizing media.
	Variety of connections Flange connections according to EN 1092-1 type 11, ANSI 150 Lbs or BSPT thread.
Casings available in Ra<0.5 μm Wetted and external parts glass blasted to Ra<3.2 μm

Special versions

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, with a simple modification it is possible to enable 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.

Tapflo CTX S industrial self-priming centrifugal pumps

Due to changes in the way we think about our impact on the environment, we are proud to present EODD – Electric Diaphragm Pumps. The product follows a modern approach but is still based on the original diaphragm pump technology, which has proven to be very effective. We consulted with our customers, who expressed a need for the features and benefits of a traditional diaphragm pump, but with the added advantage of lower operating costs. The pump is powered by a high-efficiency electric motor (IE3 class) and there is no chance of hydraulic fluid leakage, as the pump simply does not need it.

A Filter Press Pump is a specialized type of pump designed to fill a filter press with a slurry or suspension from an external storage or disposal facility, typically used in solid-liquid separation processes, typically at high pressures reaching 24 bar.

Tapflo Filter Press Pumps are known for their robust construction, reliable performance, and ability to handle high-pressure applications with ease. They are equipped with a non-return valve to prevent backflow and are available in various materials to suit different process requirements. Air operated filter press pumps have the unique feature that when the filter press is full, they stop and no additional safety systems are required to shut down the pump (like in case of electrically operated filter press pumps).

Tapflo offers a wide range of centrifugal pumps made of stainless steel and PP and PVDF plastics, including horizontal or vertical pumps, as well as magnetically driven pumps. Available in hygienic and industrial designs, Tapflo centrifugal pumps are among the most versatile pumps currently available on the market. Selected pumps can be designed for safe contact with food and are also available in ATEX explosion-proof versions.

Hose pump is a type of positive displacement pump that can be used to pump a wide variety of liquids. Tapflo industrial hose pumps use the principle of peristalsis, whereby the deformation and compression of a soft elastomer hose allows the liquid to pass through the device.

Pumps of this type are the best solution for delicate, corrosive, abrasive or dry media, including those containing solid particles. The special design, in which only the hose comes into contact with the pumped product, reduces operating costs by reducing wear on internal components and allows operation in very demanding conditions.

The SOMA SINUSOIDAL Positive Displacement Pump works according the Sinusoidal PUMP principle, which was developed by Manfred Sommer in 1982. The Sinusoidal curve shaped rotor is fitted on a pump shaft. Due to the design, four chambers are created in which the product will be transferred very gently – without any shear or damage to the product.
A scraper divides the suction and the pressure side. The rotor does not run against the housing or the cover. That means, that the housing and the cover will never wear out. SOMA offers an unlimited guarantee for the cover and the housing.

IBC containers and drums are widely used in industry – they are the simplest way to store and transport various liquids. Since many of these liquids must be mixed before use in the process, we offer a range of dedicated industrial mixers. These are simple, yet robust and safe to operate, high-quality devices. Designed and configured for common industrial applications, they enable mixing directly in the IBC container or drum. Thanks to the use of mixers, intermediate tanks can be omitted and the process becomes faster and more economical.

Our offer is complemented by pump units, industrial trucks, acoustic and thermal shields, and SKID technological systems.

SLES* is an organic chemical compound with excellent cleaning and foaming properties. For this reason, it is commonly used in the production of cleaning agents, soaps, shampoos, and household chemicals. SLES is typically supplied to manufacturers of these liquids at a 70% concentration, and due to its physical properties, such a concentrated solution is difficult to process and must be diluted below 27% before being used in the production line. Our system enables continuous dilution with maximum efficiency and safety, reducing costs for the company in the long term.

Achieving precise mixing of ingredients to obtain the desired final product—while maintaining strict proportions, accuracy, and sequence—poses a major challenge for industrial manufacturers. The mixer was created specifically for this purpose. It is based on a system for diluting concentrated ingredients such as SLES. However, it has been designed in a modular way, allowing us to easily configure the system to meet actual production needs. The ingredients of the final product can be drawn from various types of tanks.

Precise and repeatable filling operations with our versatile container filler. Designed for applications requiring high accuracy and compatibility with various containers and products, from small-volume containers to large industrial drums.
