CTX High Performance Centrifugal Pump

The CTX range includes an industrial execution, CTX I, and a hygienic execution, CTX H, to allow this range to be used across various applications.

The CTX I and CTX H can reach higher pressures and are available in larger sizes for a wider flow range than their standard CTI and CTH counterparts.

Customers of the CTX Range may expect long-term, trouble-free operation and minimal downtime during maintenance periods thanks to the high specific strength, compact design, and reliable design.

The CTX’s architecture is defined by its “modular Product Concept,” which allows for Flow Rates up to 125 m3/hr and Max Discharge Heads of 88 m. The CTX is easily adaptable and upgradeable to a variety of applications, making pump maintenance and parts stocking simple, low-cost, and manageable.

Though originally designed for tank-to-tank transfer applications, it can also be used for the following:

Pressure boosting
Dispensing
Loading and offloading
Tank cleaning
Batching and metering

For diverse application conditions

The CTX-H Pump range is suitable for a variety of hygienic applications within the food, beverage, chemical and pharmaceutical industries, whilst the CTX-I is suitable for the chemical and pharmaceutical industries where there is the requirement to transfer products from storage tanks or containers. Find a few examples of applications below.

Edible oil
Alcohol
Juice
Dairy – transferring butter, cheese, ice cream, milk, yoghurt
Transfer of cleaning liquids and water
SLES
Solvents
Waste Products
Soap

Designed for quality performance

The CTX Range follows a modular concept which allows more flexibility in how the pump can adapt to different application conditions and is easily upgraded to meet changing requirements due to the interchangeability of parts.

Interchangeable parts available:

13 motor sizes
9 lantern sizes
8 shaft sizes
2 seal sizes
3 back cover sizes
10 impeller sizes
10 casing sizes

Impeller

The CTX is designed with a multi-facet open impeller which benefits the pump by stabilising operation and reducing noise and vibrations emitted by the pump.

Open impellers are also ideal for handling applications that are highly viscous and/or have suspended solids.

Tapflo can trim and adapt the impeller to meet the needs of the process media.

Additional design features

Hygienic mechanical seal arrangement which is located on the dry side of the pump which ensures that the mechanical seal doesn’t come into contact with the process medium and means the pump is fully cleanable.

Double Mechanical Seal Option available

Supplier motors feature a built-in inverter which provides full control to the user during operation by influencing the speed of the motor.

Adjustable feet ensure simple adaptation of the pump to the location it is fitted into, including if the location changes.

Brackets to allow the pump to be permanently fixed to avoid movement during operation.

The casing and impeller designs have been optimised for outstanding performance. The shape of the chamber and the impeller are a result of an advanced multivariate analysis and numerous performance tests to ensure that the complete pump design delivers an efficient flow of liquid for end users.

Variety of connections for CTX I and CTX H executions

CTX I: flanged connections according to EN 1092-1 type 11, ANSI 150 or BSPT

CTH H: DIN 1185, DIN 32676 and others on request

Casing Design

CTX I: wetted parts and external surfaces are sandblasted Ra <3.2

CTX H: wetted parts mirror polished to Ra<0.8 as standard (Ra <0.5 on request), external surfaces sandblasted to Ra <3.2

CTX H, High Performance Centrifugal Pump with shroud

Hygienic Design features a shroud

Hygienic shrouds are available for the motor of the CTX H, manufactured from AISI 304L. The shroud acts as protection against flooding and water spray during the pump cleaning process.

Mobile Solutions

The CTX range can also be fitted to a Tapflo trolley unit to provide a mobile pump solution. Ask a member of the team about our bespoke trolley solutions when you enquire!
