Complete CDR Guide for Choosing the Best Pump for Corrosive Acids

When talking about corrosive acid pump, the priority is to ensure safety, reliability, and resistance to the most aggressive fluids. Acids used in industrial processes, such as citric acid, hydrofluoric acid, or hydrochloric acid, can compromise the structure of an inadequate pump in a few moments, and therefore require pumping solutions that avoid any risk of environmental loss or contamination.

The Magnetic drive centrifugal pumps represent today the most effective solution to these needs, combining high performance with completely sealed operation, without mechanical seals that could be subject to wear.

In CDR Pompe, these solutions are accompanied by extensive technical consulting services and After-sales support, with a catalog of magnetic drive models designed to fit a wide variety of applications and work environments.

Why choose a magnetic drive centrifugal pump

The Magnetic drive centrifugal pumps are the most technologically advanced solutions currently available for handling toxic and corrosive fluids. Compared to their mechanical seal counterparts, they are distinguished by their sealed structure: instead of a drive shaft passing through the pump housing, motion is transferred via a permanent magnet coupling, one fixed to the motor and one connected to the impeller. The Acid-resistant pumps Magnetic dragging prevents spills even under strenuous working conditions, ensuring maximum possible safety for both operators and equipment.

The absence of mechanical seals further reduces the need for maintenance ed avoid contact between metal components and acids, ensuring consistent performance even at high temperatures and pressures.

CDR Pompe’s commitment to preventing the release of corrosive or toxic substances into the environment is in line with our company's commitment to sustainability. The same commitment that we try to demonstrate every day with projects like the installation of a 100 kW photovoltaic system and the EcoVadis certification, concrete testimonials of responsible production focused on safeguarding the planet and promoting the circular economy.

Materials available for CDR corrosive acid pumps

The choice of material is fundamental in the design and installation of a corrosive acid pump. Every industrial application and every production sector has its own unique specifications and characteristics, such as Temperature, concentration, pressure, and cycle duration, which directly affect the durability of the pump body and the parts in contact with the fluid. CDR Pompe offers a comprehensive range of high-performance materials, selected based on decades of experience in handling aggressive substances in environments Industrial, chemists e pharmaceuticals.

One Magnetic drive pump for corrosive acids CDR can be made with three types of materials:

• Polypropylene Lightweight and durable material, ideal for weak acids or low temperatures. Excellent balance between cost and longevity.

• PVDF (Polyvinylidene Fluoride): Excellent chemical and thermal resistance; perfect for medium-aggressive acids and higher temperature processes.

• PFA (Perfluoroalkoxy): Reference material for extreme conditions. It guarantees maximum chemical resistance and dimensional stability even with highly concentrated acids or at elevated temperatures.

Thanks to this variety of choice, CDR is able to provide the corrosive acid pump better suited to any production context, always ensuring efficiency, safety, and longevity.

CDR centrifugal pumps for acids: efficiency and compatibility

As we have seen, the CDR magnetic drive centrifugal pumps They are designed to efficiently and seamlessly handle complex, hazardous, and corrosive fluids. However, each construction material is selected based on the type of acid, concentration, and operating temperature.

• Citric acid Used in the food, pharmaceutical, and cosmetics industries for its chelating and acidifying properties; compatible with materials such as PP e PVDF.

• Hydrofluoric acid: used in glass processing, semiconductor manufacturing, and metal surface cleaning; requires highly resistant materials such as Please find attached e PVDF.

• Hydrochloric acid Widespread across many industrial sectors, from basic chemicals to water treatment and electroplating; it can be safely managed with PP, PVDF o Please find attached, based on concentration and temperature.

The Perfect compatibility between fluid and material is what ensures them Acid-resistant pumps CDR for long operational life and consistently constant performance even under extreme working conditions.

Advantages of CDR pumps for corrosive acids

Rely on a Magnetic drive pump for corrosive acids CDR means choosing a solution designed to minimize dispersal and downtime risks and maximize the performance of the production department, while ensuring operational safety. CDR pumps combine advanced technology and high-quality materials, ensuring continuity of service even in the most complex applications.

• Zero fluid leakage: The absence of mechanical seals eliminates the risk of leaks, protecting operators and the environment.

• Superior chemical and thermal resistance: The selected materials are long-lasting, even in the presence of concentrated acids and high temperatures.

• Reduced maintenance: The simple and modular structure allows for quick and less frequent interventions, reducing management costs.

• Efficiency and long-term durability: Careful design ensures constant and reliable operation, even during prolonged cycles.

For companies that handle hazardous substances, operational and environmental safety always comes first with the Acid-resistant pumps CDRs become a guarantee.

CDR models suitable for corrosive acids

Within the CDR catalog, three models represent excellence in acid treatment, namely the pumps from the ranges DTN, ETN e UTN.

Pumps DTN, available in versions DTN ISO e DTN ASME, they offer top-tier hydraulic performance thanks to the special configuration of the shaft and impeller, improving flow rate, head, and energy efficiency. The introduction of the version with dynamic tree Increases reliability and ensures optimal axial thrust along the entire operating curve. Designed to meet the needs of sectors chemical and pharmaceutical, The DTN range finds application in basic and fine chemistry and petrochemical processes, in the production of active ingredients, and in air treatment in industrial plants.

The ETN They are distinguished by their robustness and ability to handle particularly aggressive fluids. Designed to ensure high performance in difficult operating conditions, they are used in sectors such as electroplating, fine chemicals, and pharmaceuticals, ensuring efficiency and safety even for intermittent pumping operations. The ETN range, coated in plastic material and fluoroplastic, reaches temperatures up to +120°, with a maximum head of 35m and a maximum flow rate of 60 m³/h.

The UTN, finally, they are the most advanced solution for extremely corrosive acids. With execution on a base (UTN-L) monoblock (UTN-BL), ensure chemical resistance and maximum safety even in the most demanding processes, such as semiconductor production or metal surface treatment. They are ideal for environments such as chemical and pharmaceutical, where ‘zero-emission’ safety is a priority.
